The tumultuous political events of the past week and subsequent investment rating downgrade continue to dominate our national discourse and preoccupation with the trajectory of our political economy; and correctly so as we seek a cogent articulation of radical socio-economic transformation and inclusive economic growth for the de-racialisation of our economy aka white monopoly capital.

It is therefore unfortunate and not unexpected that our attendance as well as media coverage of the Construction Summit held last week in Midrand has been drowned out and overtaken by other bigger national events beyond our control as alluded to above.

Our previous theme of “Courage and resilience in the face of adversity” could not be more relevant under these circumstances. It is therefore important that we do not lose sight of the positive intent and beneficial impact of the Voluntary Rebuilding Programme (VRP); and associated Declaration of Integrity (DoI) that was the predominant subject of the Construction Summit as a potentially strategic tool for the advancement of transformation in our industry/sector.

Master Builders South Africa affirmed its commitment to this new covenant as a blueprint and strategic road map for real, meaningful and sustainable transformation in our sector. While we acknowledge that it is not a perfect document, its foundational and ground-breaking aspects cannot be ignored. It is therefore up to all roleplayers as well as all interested and affected parties to play their part in the realisation of its vision, objectives and “desired end-state” for the benefit of the industry as a whole.

We remain steadfast in our belief that the VRP together with the new Preferential Procurement Regulations and the imminent Construction Sector Charter Codes will deepen and accelerate transformation in the construction industry bearing in mind that transformation is a long-term project.

It was also heartening to read that the FNB/BER Building Confidence Index

improved for the third consecutive quarter, rising by three points to 43 in 1Q2017, marking the highest confidence in more than a year. However, even though confidence improved, the current level of the index indicates that the majority (close to 60%) of respondents are dissatisfied with prevailing business conditions. The investment downgrade will most certainly exacerbate this sentiment unfortunately.

This will no doubt undermine confidence in the public infrastructure build programme operating under the slogan “Turn South Africa into a Construction Site” considering that public expenditure accounts for about 55% of total construction expenditure. This is also against a 14% decline in total capital expenditure in 2016 by state-owned entities.

It was therefore somewhat reassuring to also read the findings of the inaugural Afrimat Construction Index which suggests that construction activity in South Africa is not as depressed as suggested by the media, large construction firms or industry analysts.

This study supports Afrimat’s argument over the last five years that construction is healthier than many people believed. This bodes well for the future despite recent political and economic setbacks by which we must not be overly panicked but remain resolute and focused; difficult as that may be under the currently over-charged political, social and economic environment of volatility, uncertainty, unpredictability, complexity and instability compounded by low growth.

I am reminded at this time of one of my favourite poems, “If” by Rudyard Kipling. “… if you can fill the unforgiving minute with 60 seconds’ worth of distance run…” Have a blessed and safe Easter. Let’s unite around Freedom Day to reclaim the promise heralded by the dawning of our new nation in 1994.

Neil Enslin, Health and Safety Manager, KwaZulu-Natal Master Builders Association

The Department of Labour recently hosted a Construction Sector Seminar to bring together industry experts and role players to discuss health and safety matters impacting the sector.

The seminar, in partnership with the South African Council for the Project and Construction Management Professions (SACPCMP), a statutory organisation established to regulate construction management and construction project management professionals to protect the public, was held under the theme: “Collective responsibility for construction health and safety”.

The seminar took place at the Square Boutique Hotel and Spa in Umhlanga, KwaZulu-Natal province and was attended by around 250 delegates from the department and industry.

Department of Labour Deputy Director-General of the Inspection and Enforcement Services, Aggy Moiloa delivered the keynote address. She shared the platform with Department of Labour Chief Inspector, Tibor Szana.

There were expert speakers from the department and its entities, the construction sector, independent consultants, industry bodies and labour representatives.

The seminar focused on Vision 2020 which centred on the following:• Constructionhealthandsafetyinthesector;• Globalkeyaspectsofconstructionhealthandsafety;• Inspector’sperspectiveofconstructionhealthand safety in South Africa;• Businessperspectiveofconstructionhealthandsafety in South Africa;• Organisedlabourperspectiveofconstructionhealth and safety in South Africa;• Anindependent perspective of construction health and safety in South Africa.

Presentations on the Construction Regulations 2014 with regards to permits, exemptions and guideline were delivered. The seminar was concluded with a panel discussion.

The theme of the conference was “Answers to burning questions” and was based on the most relevant and frequently asked questions received from the industry. This is according to reports by

Marc Jacobson of RNews and Diona Vermaak, EC MBA's Occupational Health and Safety Manager. The conference covered important topics that needed addressing in the industry, with presentations by renowned specialists in the field:

The topics dealt with were: • “Health and Safety from Client stage to Site

implementation” – by Prof John Smallwood• “Safety, A Habit” – by Donevin Lesch• “Occupational Medical Surveillance”

– by Dr Claire Deacon

“The event was very well attended and well received,” said Vermaak. “And these topics were eagerly anticipated and provided the audience and members in attendance with a deeper understanding of the regulations and their application in the building and construction industry.”

Professor John Smallwood touched on the importance of addressing health and safety at the design stages of the project and including the correct information in the tender documents and H&S specifications to ensure contractors price correctly for the project.

Donevin Lesch raised the issue of having so much paperwork on site and having great legislation in South Africa – yet we are still having so many accidents. He mentioned how we need to change habits, correct attitudes and ensure employees are correctly trained on site. The safety file kept in the site office must correspond with the actual events on the site.

“The health risks relative to construction activities are not well understood and therefore not applied to the benefit of the workers, or for those who get exposed,” said Dr Claire Deacon of Occumed – Occupational Health & Safety Consultants, regarding the underlying issue.

She reiterated that health surveillance and regulations on work sites are largely inadequate, due to the fact that a ‘one size fits all’ approach is taken, meaning overall health issues do not always get applied.

“Concerning employers don’t really apply the overall health issues that workers are exposed to at work during their employment, and as a result, critical exposure may be missed,” Dr Deacon said.

The main challenge of these implementations being that symptoms of such concerning exposures in the building environment are missed and not taken note of, and thus hindering the opportunity to foreground the protection of those affected.

“Medical surveillance needs to be enforced over all projects, irrespective of size, but the challenge is the ‘loss’ of data as many are sent through surveillance for every project, which

in some instances could be deemed as invasive in terms of the Employment Equity Act,” said Dr Deacon regarding health check measurements.

With regards to permanent employment, Dr Deacon emphasised that contractors should be placed on a regular health check program.

“Contractors should be on a regular programme, at least annually, but would be determined by a risk exposure

profile. Community or temporary workers would be done on pre-employment, periodic and at exit,” she said.

For some solutions regarding the aforementioned issues, Dr. Deacon stated: “A centralised data base for medicals is needed, and the adoption of the appropriate actions need to exercised.

“I have an instrument that was tested in my Masters, and an adapted version is currently used by the Green Building Council of South Africa (GBCSA). The use of a standard such as that would be advisable,” she concluded.

In the global age, organisations are increasingly focused on the big picture. But, with the means to connect with anyone anywhere, the value of the individual is diluted. This can affect how people perceive their organisational

worth, affecting their productivity and your ROI.

Several studies indicate that the world of work will change radically in the next two to five years. Health and safety concepts that focus on the individual, like lean manufacturing, organisational excellence and the learning organisation, will become fundamental to the sustainability of organisations of the future. But what does this mean for businesses on the ground?

The importance of health and safetyOrganisational health and safety is a multidisciplinary field concerned with the safety, health and welfare of people at work. Important national and international laws, standards and guidelines exist to govern this arena, with the potential to reduce costs to your organisation, the employees themselves, and the communities in which they’re a part.

The basic regulations, however, are not enough to instil tangible well-being; most companies offer that. Real engagement requires an authentic, pervasive investment in the individual. Lean manufacturing and learning endeavours that strive for corporate excellence, for instance, are about minimising waste, maximising efficiency and embracing an integrated community culture.

In the future, all organisations, irrespective of industry, will have to focus on creating an engaged and positive workforce if they are to remain competitive. After all, studies indicate that personally invested employees are 15% to 18% more productive than those who aren’t.

In your company’s best interests You might assume that the kind of people investments referred to here would knock your bottom line, but evidence suggests the opposite; they’re surprisingly profitable. In fact, workforce health and wellness programmes are positively associated with companies’ financial performance – due, among other things, to:

• Reduced risks• Fewer accidents• Lower absenteeism and turnover• Improved supplier and partner relationships• Strengthened reputation• Increased productivity

Corporate wellness programmesA common approach to organisational health and safety is

implementing a corporate wellness programme. Evidence suggests that organisations using these initiatives reduce absenteeism by as much as 2,6 days per employee per year, with a return of R4 on every rand invested.

The focus of these wellness programmes on physical wellness, however, isn’t necessarily enough. Dr Deonie Botha, Strategic Manager at Sebata, says, “The scope and organisational reach of occupational health and safety should be broadened to include aspects relating to the psychosocial wellness of employees. The divide between physical health and safety and psychosocial wellness are superfluous, since more organisations are starting to realise that the two aspects cannot be separated.”

Studies show that mental illness contributes to high levels of absenteeism, poor work quality and impaired productivity. The social cost of mental illness is also severe, as these issues fuel a cycle of consequences that include substance abuse, crime, violence and marital and family breakdowns . . . all factors that chip away at employee engagement and performance.

Analysing successful initiativesIt’s understandable, and it has been proven by countless studies, that employees feel physically and psychologically secure when they are engaged and fulfilled. To achieve this, it makes sense for companies to adopt an operational excellence framework that addresses business strategy, leadership development, and cultural transformation.

Specifically, the most engaged employees work in environments that are comfortable, uncrowded, quiet when necessary, and positively stimulating, with plenty of fresh air. Further, ‘good’ environments also offer psychological support, a fair and honest company culture, respect, growth, recognition, influence and a manageable workload.

Such workplaces, however, cannot be achieved through the efforts of a single department; they require a tangible investment on a corporate level. In other words: real, sustainable employee wellness is a leadership-driven initiative, not an HR-driven one.

The future of health and safetyAccording to Dr Botha, some of the international trends in workplace health and safety include:• Pervasive technologies and increased levels of automation• The rise of big data and the Internet of Things• Predictive and prescriptive analytics• A focus on health, safety and environment and its effect on productivity

• Experiential workplaces, and training that is increasingly virtual and visual • Wearable technologies serving as personal protective equipment• Auditing beyond commonalities to extremities• Effectively managing an ageing workforce• Nano-materials and their effect on workers

Dr Botha also notes that there’s been a recent shift to applying neuro-psychological principles to safety management. She says, “By using neuro-imaging techniques, neuroscientists can now make precise inferences on what is going on inside the brain, and how it relates to observable behaviour. By understanding this,

businesses could find smart ways to influence behaviour, and create lower-risk work environments.”

What’s the final analysis?The evidence is mounting in favour of investing in the people in your organisation. Employees want to feel noticed; special; like they make a difference. With happy, engaged staff, positive financial returns, and a competitive edge, there’s no surprise that some of the world’s most successful organisations are adopting these strategies. As for the South African market, the comparatively slow uptake has created a notable gap that could yield some exceptional returns.

Nunnovation Africa Foundation (NAF) has established a unique programme to develop and support entrepreneurs in the construction input manufacturing sector. The ‘Construction Input

Incubation Programme’ is targeted at the Merafong and Rand West communities in Gauteng’s West Rand. Now in the final stages of the recruitment process, this exciting initiative is set to change the lives of entrepreneurs and their communities in the region.

Ngwako Ramohlale, CEO at NAF says, “Changing the face of economic development in the country is very important to us. All our programmes are designed to inform, educate and inspire people from our communities while increasing their earning potential to improve their lives. The construction industry will benefit greatly from this transformation initiative and we pride ourselves in being the change agents to influence this much-needed change.”

The recruitment process started in November 2016 and is now in the final stage of selecting the 30 beneficiaries who will be incubated for the next 18 months. The Incubation Programme will officially be launched at the Incubation facility based in Westonaria in April 2017.

Nunnovation has several empowerment programmes aimed at equipping historically disadvantaged individuals from various communities with industry specific skills across industries. The Construction Input Incubation Programme is geared to develop small businesses in manufacturing steel, rainwater, paint, cement and carpentry products.

Funded by various organisations including Sibanye Gold (Pty) Ltd, and the Department of Small Business Development, the vision for the programme is to elevate entrepreneurs beyond mere survivalist modes of operation to sustainable black-owned manufacturing enterprises. This project is aimed at boosting the local economy of Westonaria and surrounding areas. The main objective is to develop specialised manufacturing technology driven products that will give them a competitive advantage in the market.

Due to the envisaged high impact results of this programme and the emerging businesses, there is the unique advantage of collaborating with each business to explore further potential and opportunities as a programme partner. As a potential partner of the programme, corporate organisations can gain substantial benefits from their association with

this programme and contribute to the drive for inclusive economic growth in the country.

“Programmes of this nature and magnitude need major financial resources to back them for the goal to be successfully realised. Creating black industrialist is our goal. The industry is teeming with opportunity and we’re excited about partnering with both public and private sector companies on key aspects for this programme,” says Zandile Mabena, Partnership and Sponsorship Manager at NAF.

Should your business have an interest in joining this ground-breaking programme, contact Zandile at: zandile@nunnovation.com

The Vision 2030 Summit – under the endorsement of the National Planning Commission – aims to publicise the activities around the implementation of the National Development Plan (NDP) and to

encourage collaboration among all stakeholders, including business, government and civil society by providing an inclusive platform for members of the Presidency, key government dignitaries and private sector leaders to share insights, engage and discuss the vision for the National Development Plan for South Africa.

The purpose of the summit is to showcase and recognise all the good work that has been done with the implementation of the National Development Plan and the opportunities that arise as a result of the coordinated effort for organisations, society and the country. Vision 2030 aims to bring the best minds and roleplayers together to identify opportunities and see how they can collaborate to

deliver the services and products quicker, so that South Africa can ecome more productive and grow faster.

The challenge of realising the NDP is a collaborative one – and public private partnerships (PPPs) are a prerequisite in order to achieve its successful execution.

“All South Africans have a responsibility to make sure that we implement the recommendations and findings of the NDP. We owe it, not only to ourselves, but also to our children and their children.” – Ryland Fisher, Editorial Director, Vision 2030.

Participate in driving the NDP at the Vision 2030 SummitThe third annual Vision 2030 Summit will be held from 21 to 22 June 2017 at the Birchwood Hotel, Gauteng. This will be an opportunity to join South Africa’s leaders in both government and the private sector to take action and drive economic acceleration and transformation to where it should be.

“CESA is dismayed by the current cabinet reshuffle. As an industry we pride ourselves on excellence in the delivery of infrastructure projects.

The current cabinet reshuffle, which we accept as being the prerogative of the President, regrettably not only runs the risk of exacerbating the already troubled economic situation we find ourselves in, but also sends out a disturbing message on rewarding mediocrity and punishing excellence. The latter is counter-intuitive to the culture we seek to establish among young engineering professionals who will be responsible for ensuring the well-being of our infrastructure for generations to come.

CESA further would like to reiterate that the country cannot afford this questionable reshuffle based on the need for more “effectiveness and efficiency” according to the President, when this flies in the face of dispensing of the very performance needed to achieve this objective. As engineers we believe that a better approach would have been to dispense of the non-performers and bring on board more performers.

The industry is already experiencing difficulty amidst corruption, appointment of consulting engineering firms that have little or no track record of delivery and even mafia style criminal activity halting construction activity. The latter

not only puts lives at risk but also affects job security in a sector where limited employment opportunities currently exist due to the already low levels of capital investment in infrastructure.

The junk status downgrade investment rating by Standard & Poor’s, a leading global credit rating agency, which emanated mostly from the political uncertainty confirmed by this ill-timed reshuffle, limits investor confidence further and will not only hamper economic growth, but will further limit our ability to create more jobs. Skilled engineering practitioners from various technical disciplines are currently being retrenched at a time when this has been identified as at least six out of the ten most scarce skills in the country.

The jury of course is always out on whether new appointees will be future star performers and whether some Ministers would have learnt from their past shortcomings. As an industry committed to the success and well-being of our country, in support of initiatives towards constructive and sustainable economic transformation, we offer our support to partner with those ministries entrusted with infrastructure delivery.

We, like all other citizens, are committed to a South Africa that benefits all, in the present and for generations to come.“

Engineers speak out on recent cabinet reshuffleConsulting Engineers South Africa (CESA) – the industry association for consulting engineers, representing a member base of over 500 companies which employ over 23 000 people in various capacities – delivered the following statement in April:

The bus rapid transit (BRT) Rea Vaya bridge linking Alexandra and Sandton was completed on schedule in April.

Engineering consultancy firms Hatch, Royal HaskoningDHV and Malani Padayachee and Associates undertook the design and planning of the project, which was funded by the Johannesburg Development Agency.

Hatch was also responsible for all procurement functions as well as construction of the project.

ws BCCEI secretary general Nick Faasen, says that

one of the council's key objectives is to create a level playing field so that the sector can thrive in a competitive environment – hence the range of

collective agreements between employers and employees.

“There are still many companies who feel that they may not be able to comply with the requirements of these agreements, but that is not a reason for them to stay away,” says Faasen.

Firstly, he says, since the publication of the BCCEI collective agreements in June 2014 it is mandatory for companies in the civil industry to register with the BCCEI.

Parties concluded five collective agreements between unions on the one hand – represented by the Building, Construction and Allied Workers Union (BCAWU) and the National Union of Mineworkers (NUM) – and employers on the other – represented by the South African Forum of Civil Engineering Contractors (SAFCEC).

The Consolidated Employers Organisation (CEO) also recently registered as an employer organisation representing employers in the civil engineering industry.

Secondly, provision has been made in all the agreements for an application for exemptions for members who are genuinely unable to comply with the minimum requirements required by the agreements, and the BCCEI has already assisted companies through the necessary procedures.

Since the signing of the BCCEI replacement constitution on 17 November 2016, companies rated 1 to 3 by the Construction Industry Development Board (CIDB), are now included into the scope of all the BCCEI collective agreements and this includes all sub-contractors that sub-contract to larger companies.

He says the board that deals with applications for exemptions and appeals is made up of independent experienced specialists who are aware of the difficult

conditions in the civil engineering sector, and consider these factors while protecting the rights of both the employers and the employees. While the BCCEI cannot ignore non-compliance within the sector, it needs to be sensitive to prevailing conditions when seeking equitable solutions to exemption applications.

“As the BCCEI, we have spent a great deal of time sharing information with businesses around the country, and emphasising that collective bargaining is not the only function of the council. One of the primary functions is to facilitate the negotiation and conclusion of collective agreements by parties to the council. Section 28 of the Labour Relations Act 66/95 accords these powers to bargaining councils expressly.

A collective agreement concluded in the BCCEI binds the parties to the council. However, the BCCEI plays a key role in the governance of conditions of employment in the civil industry and all the council’s agreements have been extended to non-parties. “We take an inclusive approach and encourage all companies to comply.”

Some of the important benefits for members are that the BCCEI concluded an industry provident fund, funeral benefit for limited duration contract (LDC) employees and voluntary medical aid.

The BCCEI is a statutory body registered with the Department of Labour and is independent, while being funded by employers and employees for the benefit of the whole industry.

Civil engineering companies urged to work closely with BCCEIThrough close cooperation with civil engineering companies across the construction sector, the Bargaining Council for the Civil Engineering Industry (BCCEI) aims to createa solid foundation for growth when the economy improves.

On 23 and 24 May 2017, an anticipated 9 000 members of the construction, cement and concrete industries are expected to attend the fifth annual African Construction and Totally

Concrete Expo at the Gallagher Convention Centre in Midrand.

This 2017 edition of Africa’s mega construction and infrastructure show will feature a range of new elements in response to the evolving African construction marketplace.

Among these will be six dedicated zones throughout the interactive indoor and outdoor exhibition, covering concrete, construction, digital construction, mechanical electrical and plumbing (MEP) services, surfaces and finishes as well as tools and equipment. In addition to the 250 exhibitors, each zone will feature a working group advisory panel. The Expo’s Programme Director, Soren du Preez, says: “The six zones ensure that the show truly represents the entire built environment value chain with something for everyone who visits.”

A highlight of the 2017 show will undoubtedly be the complementary Thought Leadership Keynote Session where the Honourable Minister of Human Settlements, Lindiwe Sisulu will be addressing delegates on creating a favourable regulatory climate for infrastructure investment in southern Africa.

Other augmentations to the expo include: the Contractor's Corner – offering Africa’s first live-streaming masterclass for boosting the soft and hard skills of building contractors; and interactive workshops on the expo floor.

Four co-located events will take place during the expo: the Smart Buildings & Infrastructure Africa Summit; Women in Construction Awards; Captains of Construction and Infrastructure Leadership Forum; and Digital Construction Speakers at the Leadership Forum include Mbulelo Tshangana, Director General of the Department of Human Settlements; Abram Masango, Group Executive of Group Capital at Eskom and John Tanui, CEO of the Konza Technopolis Development Authority from Kenya.

The Women in Construction Awards enables the industry to celebrate its women pioneers and rising stars who have made a vital contribution to development. Hosted as a gala dinner in 2017, this prestigious awards ceremony promotes gender empowerment and industry transformation.

“That was 39 years ago, and the roads and houses are still in perfect condition, even though traffic throughput has been at a far greater speed than the original roadways were designed for,” said Tony van der Berg,

technical executive at the IS Group. “We visited Aggeneys 15 years ago with engineers from the Black Mountain Group who confirmed that they had conducted no maintenance whatsoever since we supplied the new Zig Zag product in 1978. We had also originally supplied a number of black hollow products for the housing project, and when visiting earlier in 2017, the product still has a good surface and appearance – testimony to our manufacturing and design capabilities and a real commendation for the use of concrete in order to obtain a longer lifespan for such applications. Since 1978 Technicrete has introduced the Double Zig Zag (DZZs) interlocking pavers which offer the same longevity and cost effectiveness through their continuous, hard wearing surface overlay. They are particularly suited for areas of heavy traffic such as municipal parking areas, petrol station forecourts, industrial and factory roads, suburban streets as well as domestic driveways. Technicrete has also announced that it's paving and kerbs products were recently applied on the Moletjie road upgrade in Polokwane:

In mid-2015 Limpopo’s Public Works and Infrastructure Department announced that R1,2 billion had been

earmarked for road refurbishment and maintenance to be rolled out over the next three years. Included in this roll-out was maintenance to a section of the Moletjie Road Project in Polokwane that was to be upgraded from gravel to paving. Technicrete’s Bond Brick and kerbs were selected for this project. Makapani Modipa, CEO of MacP Construction said: “There was no established pavement on this section of Moletjie Road, it was a gravel walkway that needed to be upgraded to a paved surface. Included along this stretch of walkway a 1,3 km bus stop had to be accommodated in the construction. “We chose the Technicrete Bond Brick and kerb products due to their durability, this was a key factor for the bus stop development in particular, due to the weight and regularity of the bus traffic,” said Modipa. “The project consisted of a combination of 50 mm Bond Bricks together with Fig 8B Kerbs, 60 mm and 80 mm Double Zig Zag Grey pavers and Fig 3's Kerbs”. “The Bond Brick is a traditional paver that offers economy and durability and is very well suited for commercial and domestic surfaces. It has been a preferred choice not only with local municipalities, but by private commercial developments as well,” said Hendrik Steenkamp, sales consultant for Technicrete ISG in Polokwane. “Our pre-cast concrete kerbs are an ideal edge restraint in the construction of roads, kerbs and gutter systems. We also can now offer our Figure C900 mountable kerb which can be utilised in traffic calming measures.” “Where heavy traffic is experienced, our Bond Brick paving blocks are perfect because of their well established reputation for longevity and quality while still offering a really good finish aesthetically,” concluded Steenkamp.

Technicrete Zig Zag block pavers last 39 yearsIn 1978, the Aggeneys mining township was developed in the Northern Cape by the then Black Mountain Group. Housing and roadways were built for the group’s employees and local residents. Technicrete, then known as Concor Precast, operated two block manufacturing plants adjacent to Aggeneys enabling them to produce the newly designed Zig Zag block pavers for the project.

Roxburgh says air and water will carry chemicals into the concrete where, in the presence of water, chemical degradation will start both in the concrete and the reinforcing steel. Concrete

should be made less permeable right at the mix design stage. Here Roxburgh provides three guidelines:

• Thefirstistoreducetheamountofvoidsintheformof capillaries and pores in the paste part of the concrete. This can be done by either reducing the water content or increasing the cement content. By doing the above the water to cement ratio (w/c) is lowered which leads to a stronger concrete – and stronger concretes are typically less permeable than weaker concretes. “This is an older, well tested and popular approach to making concrete less permeable. However, it can be an expensive approach if the cement content is increased. So, with an optimal amount of cement, mix designers should concentrate on reducing the amount of water. It is the excess water in concrete that is responsible for the capillary and pore sizes and overall volumes. Here admixtures and especially the plasticising admixture will play an important role in the reduction of the water content in concrete,” he advises.

• Amoremodernapproachistouseextendersasa portion of the binder. Using fly ash will result in a finer pore structure being produced within the paste with a resulting reduction in permeability. Similar outcomes can be produced with slag-based cements, especially with longer curing times and post 28-day ages. Silica fume and to a lesser extent finer fly ash will also densify the usually less dense transition zone between the paste and aggregate so helping the concrete to become less permeable. “The reduction in permeability

can be quite dramatic with the use of silica fume,” Roxburgh observes.• Finally,theuseofwellgradedsmoothroundedsands that pack well will reduce water resulting in a less permeable concrete. Fundamental to producing a cheap but durable concrete is to use a good sand.

“Concrete mix design to reduce the permeability of the concrete should also always be considered along with the plastic properties of the concrete. On site, the formation of cracks, voids and bleed water lenses and channels within the concrete will cause permeable concrete so the plastic properties of the concrete should be designed to minimise these. Also the transport, placing, compaction and curing of the concrete plays just as an important role in the reduction of permeability as the original mix design,” Roxburgh adds.

Reduce permeability to make concrete more durableMany concrete durability problems can be prevented if the concrete is made less permeable, says John Roxburgh, lecturer at The Concrete Institute’s School of Concrete Technology.

A completed section of the concrete road leading from the new Thokoza fire station to Khumalo Street

Anew fire station is being built in the heart of Thokoza on Khumalo Street. The building and civil work contractor, Buildagain Projects 203, is on schedule to complete the project on time for the

Ekurhuleni Metro Municipality Disaster and Emergency Management Services (DEMS).

When completed, the fire station will comprise a concrete structure building, a heavy-duty parking facility for the fire trucks, a wash bay, a generator room and first aid facilities.

“The contract also includes a large area of external works,” Ravine Perumal, managing member of Buildagain Projects 203, tells South African Builder.

In total the external works make up 4 500 m2 and include a concrete hardstand area, a concrete road leading from the fire station site to Khumalo Street and a parking area for 38 vehicles.

“We’ve partnered with AfriSam on previous building and civil projects and when we saw the volumes and technical aspects of the concrete works on this contract we knew we’d be able to rely on the timeous delivery of readymix from the company as well as its reliable pumping services,” Perumal says.

Significantly, Buildagain Projects 203 secured the project on open tender, and Perumal says the contractor is proud to be associated with this vital structure that will bring much needed protection to the community of Thokoza.

AfriSam has supplied customised suspended slab, surface bed and foundation mixes to the project as well as G5 and

G6 aggregates for the base layers of the external works. During construction of the building structure 2 500 m3 of readymix concrete was used while 1 700 m3 of readymix has been used to date to construct the external elements.

“AfriSam will supply a total of 3 700 m3 of readymix to the Thokoza fire station project,” Amit Dawneerangen, AfriSam national sales manager Gauteng, says. “For the external works we will be supplying a total of 3 390 tons of G5 and G6 materials for 6 000 m3 of layer works,” he adds.

The site sits atop dolomitic ground resulting in the need for substantial raft foundations with a depth of 1 metre. A total of 1 500 m3 of readymix concrete and 380 tons of reinforcing was used during the laying of these foundations. In terms of decking, the building structure was intricate as decks required multiple beams in various dimensions. “For this

reason we used timber formwork that we could cut and adjust accordingly,” Perumal explains.

“We used a formwork team from the local community and brought them in-house under guidance from our existing foremen,” he continues.

“Our service from AfriSam has been terrific in terms of delivering on time and product quality,” Perumal states. “For a project like this, where every element is being constructed with concrete, the service received was crucial to ensure we could meet the construction programme and client deadline,” he continues.

The building architecture is modern and features glass and concrete work as aesthetic elements. The floors of the three-storey building will be finished with an epoxy layer and lots of the finishing components are aluminium.

The ground floor of the fire station consists of offices and parking bays for fire trucks, and first-aid facilities while the first floor has ablution facilities, a lift shaft and a large

volume open area for exercising and recreation. On the second floor sits the control tower and a “green” area that will become another entertainment and recreation area for firemen that will afford them a 360 degree view of the surrounding areas.

Buildagain Projects 203 is a 100% BBEEE building and civils contractor founded in 2002 by Ravine and Sangeetha Perumal. It has 6CE PE & 6GB PE contractor grading from the CIDB and is a registered member of the National Home Builders Registration Council.

Elematic South Africa’s high-quality precast hollow core concrete slabs and top notch service on the Carlswald Luxury Apartments development in Midrand secured the company a good pipeline of

future work from the estate’s developer, Century Property Developments.

The 470 units, configured in 86 blocks, were developed and built in a single phase by Century Property Developments between May 2015 and October 2016. The development also includes a variety of amenities such as a multi-purpose hall, club house, swimming pool, braai facilities, tennis court with pavilion, children’s play areas, outdoor gyms, a skate park, a bird hide and a Spark School for the children of residents.

Elematic South Africa (ESA) supplied all the precast hollow core concrete slabs for the project, supplying about 55 000 m2 in total. Hendry Brand of Century Property Developments explains that precast hollow core slabs were selected primarily because of the speed they offer in comparison to cast-in-situ concrete slabs. Overall, the construction team was able to complete approximately 40 units per month – an achievement which would not have been possible without careful planning, coordination and team work.

In that respect, Brand is highly complimentary about the service Century Property Development received from ESA. “To begin with, there were a number of different designs that had to be catered for because of the various different apartment and block configurations.

We used all the different thicknesses of concrete slabs available – sometimes we even used them all on a single floor,” he notes. Prior to construction the Century Property Developments team, including its in-house architects, sat with the ESA team to look at ways of optimising the structures for economies of scale, and to value engineer for cost-effectiveness.

There was an ESA team on site almost constantly for the duration of the project, measuring up and installing the slabs, which were on the critical path for project completion. Brand reports that Century Property Developments has been very pleased with both the quality of the slabs and the service received from ESA. “In terms of price, quality, service and our working relationship, we really do get the whole package from ESA,” he says.

“We need a high-quality product because we want longevity in our buildings, especially since they are for the rental market. At the same time, we also need to find ways of optimising our costs, which can escalate quickly on a project of this size,” continues Brand. ESA’s willingness to explore options with the client, whilst maintaining high attention to detail and not compromising on product quality, helped ensure the successful delivery of Carlswald Luxury Apartments.

“We make every effort to explore options and to value engineer each project with our clients,” notes Craig Webber, director at ESA. “We also try to improve continually on what we have done before.” This meeting of minds has resulted in a good working relationship with Century Property Developments, which has awarded ESA a number of other contracts subsequent to this one. “There are benefits to working with the same contractors and suppliers if we can,” comments Brand. “The ESA team know what questions to ask, they know how we work and they are extremely thorough. Like us, they take pride in their work. We also find that working with people we know means we don’t have to go through a process of trial and error with a new contractor for every project, because that can result in costly mistakes,” he adds.

With a number of new projects in the pipeline, both parties look forward to an ongoing mutually beneficial relationship.

Perrie says pervious concrete or permeable block paving in roads and parking areas – which is still relatively under-utilised in South Africa – allows rain and other water to percolate through to

replenish natural underground water resources. “Boosting aquifers in this manner is important during prolonged spells of drought as South Africa is currently experiencing – particularly when concern has already been expressed about the alarming diminishing of our underground water volumes.

“Pervious concrete or permeable block paving naturally filters out pollutants that come into contact with it in contrast with the voluminous run-off from impervious surfaces that inevitably ends up in surrounding streams, rivers and dams, resulting in grease and chemical pollution hazardous to animal and human life. Pervious concrete can also be used for storm water attenuation in place of retention ponds. This will reduce the number and size of drainage infrastructure elements, saving both materials and energy, as well as reducing future maintenance,” Perrie adds.

American studies have found that oil that drips on, and into, pervious concrete pavement, is contained within the pervious system as a coating on the large surface area of the void system, and at the location of any geotextile fabric separating the pavement from the sub-base or sub-grade support. Hydrocarbons, such as oils, then become a food source for many naturally occurring bacteria and fungi that feed on the oil and biodegrade it into simpler chemical components that are released into the atmosphere.

“Research has determined that 97,6 to over 99% of oils introduced into pervious pavements are trapped and biodegraded instead of ending in rivers and dams,” Perrie states.

USA storm water regulations set limits on the levels of pollution in American streams and lakes. To meet these regulations, local officials have considered two

basic approaches: • To reduce the overall run-off from an area; and • To reduce the level of pollution contained in run-off.

In order to reduce the level of pollution from storm water, developers should provide systems that collect the first flush of rainfall, usually about 25 mm, and “treat” the pollution in this rain prior to release. Pervious concrete pavements can reduce or eliminate run-off and permit such treatment of pollution.

By capturing the first flush of rainfall and allowing it to percolate into the ground, soil chemistry and biology can then “treat” the polluted water naturally. Thus, storm water retention areas may be reduced or eliminated, allowing increased land use. Furthermore, by collecting rainfall and allowing it to infiltrate, groundwater replenishment is increased, peak water flow through drainage channels is reduced, and flooding is minimised.

In the US, factoring impervious concrete into new property developments has the potential of earning credits in the US Green Building Council’s Leadership in Energy & Environmental Design (LEED) Green Building Rating System.

Pervious concrete pavement is also ideal for protecting trees in a paved environment as many plants have difficulty growing in areas covered by impervious pavements, side-walks and landscaping, because air and water struggle to reach their roots. However, when pervious concrete pavements or side walks surround plants and trees, the vegetation receives more growth stimulating air and water while vehicular and pedestrian use of the pavement is not impaired.

‘’Property owners and developers should also strongly consider pervious concrete purely for economic reasons. Such pavements and side-walks can provide decades of service with little or no maintenance requirements,” Perrie adds.

Permeable concrete surfaces could boost underground water levelsPervious concrete ground surfaces could play a vital role in preserving water in drought-ravaged South Africa, says Bryan Perrie, managing director of The Concrete Institute.

Following the installation of a CDE EvoWash 72 on their sister company’s site Analiza, South African brick and block manufacturer Multi Crete Bricks “just can’t keep up with orders”, according to its CEO, Christo Niemand.

Multi Crete has been supplying the South African construction industry for 16 years, delivering premier quality brick and block products nationwide as well as supplying customers directly at their Brakpan factory. The company not only ensures that the best raw materials are selected but also guarantees the best end product by overseeing production from start to finish. In 2016, Multi Crete saw an opportunity to take the lead in the local materials washing market. To achieve this, an upgrade of its sand screw washing plant was necessary in order to remedy the substantial loss of valuable fines that ended up in its quarry’s dam. By installing a new CDE EvoWash sand washing plant on its Analiza quarry, Multi Crete can now continue to produce its own bricks, blocks, and manufactured washed sands with an additional plaster sand. Christo Niemand, CEO of Multi Crete, sought out the best value-for-money washing solution that would significantly reduce the amount of lost fines, increase production levels and sand quality, and crucially allow for multiple sands to be manufactured. The objective was to boost Multi Crete’s product offering and subsequent demand. The CDE EvoWash 72 dual sand washing plant met all of these needs. Niemand explains: “Our plaster sand is hands-down the best in the region and being able to produce two products at the same time, including plaster sand, is truly remarkable.” The Analiza quarry now produces 23 tons per hour of plaster sand and 19 tons per hour of river sand. The EvoWash allows for two products to be produced at the same time and can also be set to alter the amount of finer sand in the end product, allowing the client to produce two off plus zero products (- 2 mm + 0 and - 6 mm + 0). Niemand concludes: “Swapping the Analiza sand screw classifier for a CDE EvoWash dual sand plant has turned out to be an excellent investment. We are saving water and time whilst increasing and diversifying materials production. We are now able to position ourselves on the local market as the leading supplier of construction materials.

“This is a crucial point in the construction of the wind farm and even more pleasing that we are not just ahead of schedule, but also on budget," said Kevin Foster, Project Manager of Khobab Wind Farm.

The wind turbines, which are 100 metres tall to allow for optimum energy production, take up to three days to erect, if prevailing weather conditions allow. The three 53 metre blades, made from fibreglass reinforced epoxy, are connected to the rotor at ground level before being lifted to the top of the turbine tower. This is a complicated lifting exercise, in which one crane raises the assembled rotor whilst another smaller crane and taglines guide the rotor into the correct position. The heaviest component is the nacelle, which contains the generator and gearbox; and weighs 82,5 tons.

This is the same team that was responsible for the installation of the wind turbines at Noupoort Wind Farm and more recently at the adjacent Loeriesfontein Wind Farm. “Working with an experienced crew makes all the difference,” added Foster.

The site was chosen because of its excellent wind resource, its proximity to national roads for wind turbine transportation, the favourable construction conditions, municipality and local stakeholder support, the straightforward electrical connection into Eskom’s Helios substation approximately 7 km south of the site, and studies which showed that there would be minimal environmental impact.

When operating at full capacity, the Khobab Wind Farm will generate approximately 563 500 MWh of clean renewable energy per year; this is expected to supply electricity to power up to 120 000 South African homes.

The South African construction industry is well placed to play a key role in the reduction of CO2 emissions, in particular cement manufacturers and clay brick production plants – many of which are in

fact well advanced in these programmes.

To this end, South African Builder attended a highly informative session about the Carbon Tax and Carbon Offsets held in March 2017 in Johannesburg under the auspices of the Spanish Chamber of Commerce in collaboration with the Minara Chamber, the Nordic Business Association and the Southern African Netherlands Chamber of Commerce (SANEC). Here leading Carbon Advisor and Director at Promethium Carbon, Harmke Immink, delivered an enlightening address entitled “How to Navigate the New Carbon Tax Law and the Call for Reduced CO2 Emission.”

Closely coupled to this address, Chief Economist at Nedbank group, Dennis Dykes, followed with insightful aspects relating to economic practicalities of carbon offset trading.

“Under the draft legislation, carbon offsets enable firms to cost-effectively lower their carbon tax liability,” said Immink. Carbon offsets are down from R120 per ton in 2012 to around R20 per ton today, resulting in many companies putting their offset programmes on pause. But with South Africa's CO2 emissions being twice the world average our generation has the enormous responsibility to mitigate climate change trends and drastically reduce carbon emissions over the next decade.”

Immink went on to describe the Peak Plateau and Decline trajectory (PPD) which is designed to govern and coordinate South Africa's reduction of CO2 emissions at national level through to 2050.

“Although there is currently much uncertainty around the structure of carbon tax, its links to carbon offsets and the implementation of the new Carbon Tax Law arising from disjointed government departments such as Treasury, the Department of the Environment and the Department of Trade and Industry – the message remains clear: companies need to keep the door open and be well prepared regarding carbon offset credits,” concluded Immink.

On the economic front, Dennis Dykes pointed out that there is much energy incentive for carbon offset trading in the manufacturing sector, in particular plant such as smelters, cement manufacturing kilns and conversion of coal fired brick-making kilns to gas.

In this vein “The nuclear deal could go badly wrong,” said Dykes, stressing that the direction South Africa should take on energy is to build renewable energy production to satisfy around 80% of the demand – thus inherently reducing the country's carbon footprint.

The sales and marketing, engineering and accounting arms of Echo Floors have been relocated to the Echo Group’s headquarter premises in Chloorkop, near Midrand, Gauteng. The Echo Floors factory, which has manufactured reinforced hollow-core floor slabs since 1982, will continue to operate from Muldersdrift with a full administrative and management staff complement.

Echo Group sales and marketing director, Melinda Esterhuizen, explains that incorporating Echo Floors’ sales and technology arms into Echo’s headquarter structure means that Echo Floors’ clients will enjoy improved levels of technical input and quicker turn arounds.

“Echo Floors project enquiries are now being channelled through our HQ engineering department which means we are better able to advise which product or combination of products is best suited to each project.

“Echo Floors has always produced the traditional reinforced slab which is generally used for building houses, townhouses, clusters and high-density housing, where the floor spans tend to be shorter. When deployed correctly, it is more economical than the pre-stressed hollow-core slab.

“Offering longer spans, pre-stressed slabs are designed to support heavier loads and can be used without internal load-bearing walls. In addition to the residential market, pre-stressed slab applications also include commercial and industrial structures which vary between three to seven storeys, and are used on community structures such as schools, clinics, office buildings, car parks and shopping centres.

“Merging the engineering function of Echo Floors into the Echo Group structure has made it easier for us to provide input on the design, engineering and construction phases of our Echo Floor clients through what we call our Total Solutions approach.

“The success of any hollow-core slab project essentially rests on the pre-planning and if we get involved in the planning stages, we are better able to bring our specialised knowledge to bear, matching the quality of our product offering with an equally high level of engineering input. This

realises better buildings design, cost-efficient slab deployment and savings for our clients.

“Our Total Solution approach means we remain involved until all the hollow-core elements are brought to successful completion. This approach provides the professional team with added flexibility and confidence, knowing we are always on hand to assist with any changes or fine-tuning, either during the design or construction phases,” says Esterhuizen.

The Echo Group’s pre-stressed slabs have several other applications besides flooring. These include: basement parking walling; warehouse walling; culvert covers for attenuation tanks; reservoir construction; and security walling.

There is considerable demand for durable outdoor seating arrangements which can be installed in a cost-effective and

easy manner, while still meeting all statutory requirements with regard to comfort and safety.

Consequently, a locally developed product, the Terraforce 4 x 4 Step block system, a combination of an accessory stair/seating block and any standard Terraforce retaining block, has become popular in South Africa and other parts of the world, and is used successfully at recreational or educational facilities.

The system requires low hardware input for manufacture, low transport costs and low inventory requirements at sales outlets. As an added benefit, the completed seating arrangements also offer a high-quality aesthetic finish.

Recently two such installations were installed by Decorton Retaining Systems, Terraforce's recommended civils company, at two schools in the Western Cape, South Africa.

The first, at Fish Hoek High School, seats 1 100 students comfortably. Says Steve Mitchell, educator at the school: “With the steps placed strategically at intervals, it naturally allows for our four school houses to be split without issues of rope or barrier tape.

"This is convenient for our athletics, cross country and annual go-cart race. It also allows for our rugby and cricket

supporters to have comfortable seating as spectators.”

"The Terraforce 4 x 4 multi seating system, a combination of an accessory stair/seating block and any standard Terraforce retaining block, has become popular in South Africa and other parts of the world.

Mitchell emphasises that the school is particularly happy with the way the seating pavilion looks: “We love that it does not look like a bare concrete structure. The blocks have been slightly coloured, so it blends in with the environment, and the edges are rounded, so you don’t get this sharp edge eating into the back of your legs when you sit on it, and visually it just looks so much better than edged concrete. Thank you Decorton for making it happen!”

The second installation, at Reddam House, Clara Anna Fontein lifestyle estate, Durbanville, is possibly the largest pavilion type seating, in South Africa, built with the 4×4 seating system. Bordering the 400 metre athletics and events track, the pavilion was built, also by Decorton Retaining, with a staircase in the centre and both ends for easier access. Says SP van Blerk, co-founder of Decorton: “The seating platform accommodates 1 600 spectators comfortably, and up to 2 000 at a push, and we have just been given the go-ahead to four metres of seating space on either side.”

the application of pre-cast concrete systems – helping client bodies and their professional teams accelerate construction times and build more durable structures.

Corestruc is working alongside A & P Civils & Trading on this project, which is being driven by the Collins Chabane Local Municipality.

The new sports complex will feature a grand stand with a seating capacity of up to 2 500 spectators. The bulk of the 18-bench podium is being built using a pre-cast concrete system from Corestruc.

The columns and rafters form the basis of the structure and were designed specifically for this grand stand, with the balance comprising the company’s standard stadia pre-cast concrete items that are adapted to specific project requirements.

Corestruc’s Russell Hobbs says that the popularity of the company’s systems can be attributed to the speed at which they can be installed, mitigating risk by allowing the most complex aspect of the complex to be completed early.

“Our teams have completed similar projects in as little as eight working days, including the pavilions for the earlier Sekgopa and Lebaka sport complexes,” says Hobbs.

The company’s teams arrived on site once A & P Civils & Trading had completed the earthworks and site terracing for the stadium.

After casting the concrete bases and installing the connection bolts, the columns were fixed in position and aligned.

With regard to challenges, each project is unique, and Hobbs says this one certainly presented its share of challenges: “We had to deploy a 160 ton mobile crane to lift and place the 20 odd back columns, each weighing in at 12 tons. Apart from the complexities of accessing the sites, we also had to strategically place it to lift each pre-cast concrete segment while work was forging ahead at the other construction faces,” says Hobbs.

The main contractor started with the brick works at the front of the grand stand to accelerate the works while Corestruc started placing the raking columns.

Gradually working its way to the back and below the structure, A & P Civils & Trading had completed more than 90% of the brick work by March, with Corestruc only having to place the roof slabs over the VIP and changing rooms to complete its aspect of the project.

By doing away with any erection and dismantling of scaffolding and formwork, as well as the large number of people working at height, the company’s technology also contributes towards a safe site.

Pre-cast concrete specialist, Corestruc makes waves in LimpopoCorestruc, a well-known construction company in Polokwane, Limpopo, specialising in modular pre-cast concrete, continues to impress with its capabilities and portfolio across projects for the public sector including reservoirs, water-treatment works, bridges and stadia, through to private sector retail, industrial and commercial property developments.

Corestruc’s pre-cast concrete systems have been widely deployed on a host of stadia construction programmes due to the many benefits they offer client bodies and their professional teams

According to Craig Sheppard, national product manager for ELB Equipment, the machines are ultra-efficient and “punch

well above their weight” when compared with traditional machines in their size and weight category. They are also extremely versatile and can provide users with a multitude of options when used on site.

“For example, our range of rammers have a number of additional attachments that can be fitted to increase options on site, whether it be for longer stem, broader or narrow plate or different setup options, it makes a difference to have a machine that provides versatility. Dependent on the application, being for paving, roads or trench-work, it is an advantage to be able to select from a wide range of attachments and pads.”

Plate compactorsOn the larger plate compactors and reversible plate compactors the range is even more versatile offering a variety of options per machine, across a wide range of models. These models range from standard forward compactors of between 70 and 100 kg in either diesel or petrol versions, to much larger reversible models of up to 440 kg and the flagship hydro-static models that weigh-in up to 778 kg.

Locally, machines of this size are more akin to walk-behind rollers, but in the case of the large Ammann hydro-static plate compactors they provide far better compaction than traditional rollers. They also have the advantage of having a smaller footprint (and are usually narrower) making them additionally suitable for use in trench applications.

The addition of up to three exciters in larger plate compactor models also

ensures that the vibration and resonance provides the quickest and best possible settling of fines for quicker and more effective compaction. Ammann also has compaction meters that can be fitted to the entire range of machines to ensure the right compaction is achieved on site.

World-leading ergonomics“Without exception, our machines are designed to be ergonomically efficient with reduced vibration transmitted to the handle, as well as having more comfortable and easier to use controls. This enables operators to work for longer hours with less risk of repetitive-type injuries which can lead to costly health and safety implications and time-lost injuries.

“What’s more, in southern Africa the machines will be fully supported by the extensive ELB Equipment branch and dealer network. Customers will also have access to ELB Equipment compaction experts to ensure that they make the right decisions for their operations,” concludes Sheppard.

Each of these products is specifically designed and formulated to fulfil the exact needs for applications such as

glazing, plumbing, fenestration, flooring, fire protection, DIY and hardware fields. In addition these products find application in the automotive, general manufacturing and mining industries, to name a few.

The following overview of a small selection of these products provides some insight as to the design detail for the application of each, the quality and tight specification – and what can therefore be expected from other products in the range.

Den Braven Hybriflex-540 - The professional versatile sealant

This is a versatile expansion joint sealer which can be used to seal all types of external or internal façade joints, expansion, construction joints and joints in precast elements. It can also be used for external walling and cladding joints, infill panel joints, curtain walling, window and door frame sealing and many other applications. It has excellent movement capability and requires minimum surface preparation.

Hybriflex-540, which conforms to the South African Green Building Council standards, is a one-component, moisture-curing, low-modulus sealant and adhesive, free from isocyanates and silicones and with a low VOC content, making it environmentally friendly. It is also chemical and tear resistant – an important criterion if one considers the chemicals and detergents used to keep floors sanitised. The product does not bubble or yellow and has high resistant to UV degradation and weathering. Ideal for use with polyethylene backing cord (available from Den Braven).The product is available in 290 ml cartridges as well as 600 ml foil packs in white, grey and beige.

The FireProtect® range

Den Braven FireProtect is a complete range of fully certified and approved passive fire products for application in expansion and connection joints, openings and surface penetrations, between fire compartments.

Passive fire protection products are the primary materials included in the construction of a building. By correctly applying these products, the fundamental and legal requirements of compartmentalisation can be met. Additionally, they contribute to the structural stability of a building and provide time to safely evacuate or clear it. Passive fire protection limits the spread of flames and smoke, which also limits the transfer and spreading of fire between fire compartments.

The Den Braven Fire Protect range consists of an FP Acrylic sealant, FP Silicone sealant, FP Hybrid sealant and FP PU foam filler. Each of these specialised products can have fire retardancy of up to four hours and international fire certifications.

Den Braven High TackHigh Tack has an extremely high initial adhesion power and can be used for adhesion of substrates of up to 25 kg with no mechanical fixing required
