I have the good fortune to work with geosynthetics for the most part of every day. I started thinking recently about how we would be able to solve problems, which are so simple with geosynthetics, without it. On a recent project, while on site, we encountered a problem. Aside from using geosynthetics, there was no other engineering solution which would have solved the problem. Some did not know about it, but once introduced to the concept and the principles, it was agreed to be the only viable solution. For the next two years GIGSA will embrace the growth of geosynthetics where most needed, in our universities. In 2016 and 2017 we have established two successful bursary programmes, and there is much more our future generations can, and will, do with geosynthetics. Yet still today, more than 30 years since geosynthetics were introduced in civil engineering, there is still ignorance of basic applications such as soil reinforcement and barrier systems, which are on the same level as ground improvement with piling and dam design. Our focus will be to plant as many seeds as we can and to keep watering them, with events, seminars, conferences and any excuse to remind to our community of the great tool we have in our hands, we just need to use it appropriately.
South Africa and geosynthetics goes back many, many years. We were pioneers in the use of geotextiles in dams and for separation. GIGSA is one of the biggest chapters of IGS as everyone
from consultants, suppliers, contractors to students wants to be part of it. GIGSA should be seen more as a legacy, a status, rather than an organization. If you are part of GIGSA it means you embrace geosynthetics and the scope and mission thereof.
Few seedlings are already breaking through the soil. There are civil engineering societies who have embraced geosynthetics, and they are looking at developing guidelines, standards and specifications to assist the engineering community in this obscure field, which from the outside may seem very complicated. SABS is one of such organizations which is slowly getting up to speed, with a boost at international level in terms of standardization of geosynthetics. Much has been done and more is in progress. I would like to invite you to join the geosynthetics technical committee where we can make geosynthetics more reliable, trustworthy and understood more clearly to be designed, manufactured, used and controlled.
Yours sincerely

Maccaferri Landfill Capping Solutions
Introduction
When a landfill reaches its full waste capacity, safety measures and environmental recovery of the area are undertaken using a capping system.
Depending on the landfill classification, different capping solutions may be used. Figure 1 illustrates an example of a capping system consisting of an intermediate cover layer (6) above the waste (7) followed by a grading layer (5). For an impermeable barrier layer, a textured HDPE geomembrane is often used (4). Figure 1.
Figure 1. Example of a capping solution.
The aim of the drainage layer (3) is to intercept, collect and dispose of the rainwater, and to avoid waterlogging of the cover. The correct operation of this system is also essential for the growth of vegetation (1), as it must guarantee the natural level of moisture in the soil. Traditionally, the drainage layer may consist of a selected gravel with a thickness of up to 0,5m (according to European standards). The outer layer (2) consists of top soil and the thickness must enable the growth and development of adequate vegetative cover.
The conventional method of a capping system can take up large quantities of material that are often not available on site, especially the drainage layer. The import and use these materials can significantly impact the installation costs. By implementing geosynthetics in a capping system, these costs can be significantly reduced.
Design Philosophy
One of the typical problems which the designer must deal with when using multi-layered materials (soil or geosynthetic) is the stability of the layer above the one below, ensuring an adequate factor of safety against sliding. This analysis is called as veneer design and it is
controlled by the interface friction angle between the materials which can be soil-soil, geosynthetics-geosynthetics or soil-geosynthetics. Their interface friction angle is characterized by a dry value and wet value which consider the presence of water in the latter one which can reach values even below 10° for soil-geomembrane, when it is wet (e.g. in a cover in the case of penetration of rainwater which has not be suitably and effectively drained or in a base barrier in the case of circulation or accumulation of leachate in a base barrier). Direct shear interface testing is required for detailed design. This way the drainage design is paramount in such design.
Soil Veneer Design
The fundamental problem for a soil layer, whether it is the granular layer inside the waterproofing system or the topsoil placed above the closing package, concerns its stability and therefore, basically, whether it reaches equilibrium with an adequate factor of safety between the forces destabilising the cover layer and the stabilising forces.
The Soil Veneer Cover Design is based on a limit equilibrium equation between the stabilising and destabilising forces applied to a generic slope of infinite length. This type of approach leads to the definition of quite complex equations, but enables the use of geosynthetic reinforcements to be taken into consideration which are placed inside the soil layer resulting in the reduction of the soil cover thickness. Maccaferri Africa uses its Design Software EpsaMac to assist in the Veneer Soil Cover Designs.
Turf mats reinforced with a polymeric geogrid or with a metallic reinforcement (MacMat® -R) or textured geogrids are mostly used given the 3D material, preferred to standard biplanar geogrids at the interface with GCD to better retain the soil (Figure 2).
Figure 2. MacMat R with geogrid (left) and steel mesh (right).
Maccaferri also supplies the range of biodegradable products BioMac and Biojute to assist in short term erosion control and promote the growth of vegetation (Figure 3).

Drainage Layer
Drainage geosynthetics can be used as an alternative to a typical granular drainage layer. These consist of a drainage core which is capable of transporting a fluid along its own plane with the aid of geotextiles and/or geomembranes coupled to the drainage core, that prevent the core itself from being clogged by the surrounding soil (Figure 4).
Figure 4. MacDrain W.
MacDrain® W consists of a UV stabilized Polypropolene geomat core with a ?W? configuration of longitudinal parallel channels. The core structure is flexible, with low to medium thickness (4 ? 10 mm), very high void ratio and medium-high compressive resistance. Due to the channel pattern, the flow capacity is higher in the longitudinal direction than in the transverse direction.
The drainage capacity can be assessed on the basis of appropriate laboratory tests conducted on the geocomposite (core and geotextile) and not only the drainage core as it would not take into account intrusion of the geotextile and soil: EN ISO 12958: Short term flow rate test ; EN ISO 13432: Compressive creep test with shear load applied; EN 13426-2: Junction peel and junction shear tests for geocomposites.; EN ISO 12957-1: Direct shear test; EN ISO 12957-2: Inclined plane test ; EN 13719: Long term protection efficiency test; ENV 13428: Impact protection test.
Although all the above-mentioned tests amongst others are importance, one of the most importance tests relative for landfill engineering is compressive creep. Maccaferri has conducted testing and research at TRI International (Austin, Texas, USA) under normal compressive creep loads of 50, 100, 200 and 500 kPa using both the Stepped Isothermal Method (SIM) and of time-temperature superposition (TTS) in accordance with ASTM D7361-07(2012) and the ISO 25619-1:2008 up to
120 years design life. In addition tests under normal and shear loads were performed to simulate drainage on slopes (cappings) with a load of 50kPa. The flow rate of the geocomposites is obtained by applying a set of Reduction Factors which take into account all the phenomena that may decrease the flow rate over the entire design life compared to the short term flow rate measured in EN ISO 12958:2010 or ASTM D4716-08 (2013) tests. Figure 6. Representative photo of a conventional Creep with Shear Testing Apparatus.
With the information obtained through performance tests, Design Data Sheets (DDS) were developed for each MacDrain product providing reduction factors for 5, 20, 50 and 120 years and up to 500kPa loading (Figure 5).
Figure 5. Example of Design Data Sheets.
Maccaferri has developed the MacFlow Studio software for facilitating designs using MacDrain geocomposites in various applications. MacFlow Studio has been engineered as an expert system, allowing one to automatically select the appropriate geocomposites for any given project, and is presently the most advanced software for geocomposite design available on the market. Maccaferri is known for being in the forefront of providing engineered better solutions, with our free softwares from slope stability and river analysis and the latest one, MacFlor and assisting engineers with 3 levels of service:

Breaking News: Feedback on IWMSA Seminar on The Risk Based Approach for Mining Residue Stockpiles and Deposits
The Institute for Waste Management of Southern Africa (IWMSA)?s Central Branch hosted a very successful seminar on the Risk Based Approach for Planning and Management of Residue Stockpiles and Residue Deposits in Rustenburg on Wednesday 24th May 2017. The following presentations were given, with each presenter tackling their topic in some detail:
In addition to sharing technical expertise, the seminar highlighted numerous changes and anticipated changes to the legal framework and regulations governing mining residue stockpile deposits and stockpiles. Several challenges to implementing a risk based approach throughout the life of a facility, such that risk is actually managed, were highlighted. The need for multi-disciplinary teams to assess risk was raised by several speakers, and it was clearly demonstrated how risk analyses could underestimate leakage from facilities by orders of magnitude. There was some debate about the definition of a ?competent person?, and concern raised about non-engineers recommending pollution control barriers. Several suggestions for improvements to the draft regulations for Planning and Management of Residue Stockpiles and Residue Deposits were made. It was heartening to see officials from the Department of Environment Affairs taking notes and engaging on this important topic. The presentations are in the process of being uploaded to the Members section on the IWMSA website for those who are interested. GIGSA would like to express their appreciation to the IWMSA for holding an event on Mining Waste. With more than 80% of waste in South Africa estimated to be generated by the mines, it is certainly not a segment that should be ignored.

MEDIA RELEASE
New approaches discussed in managing mine residue stockpiles (cont.)
The workshop provided a valuable opportunity for participants to better understand the proposed amendments to the National Environment Management Waste Act of 2008. Jonathan Shamrock, Vice President of the IWMSA explains: ?The changes, presented late last year by the Minister of Environmental Affairs, Edna Molewa, favour a risk-based approach that should be followed when managing residue stockpiles and deposits on mines. The main aim of this approach is to allow for a pollution control barrier system to be determined on a case by case basis, based on a risk analysis conducted by a competent person.?
Industry leaders gathered to discuss the proposed amendments and learn from experts in the field of mine residue deposits and stockpiles management. The morning proved to be insightful with stimulating discussion time for all those attending. Marius van Zyl, Technical Director at Jones & Wagener, explained the new Risk-Based Approach which makes use of the Source ? Pathway ? Receptor Concept: ?The model starts with the source; where the pollution comes from. This can be anything from vehicle exhaust emissions to drums that leak oil.? Van Zyl further explained that ?Pathway? is the term given to ?the medium by which the pollution will travel through the environment, such as air, land or water? and the Receptor is who or what could be affected by the pollution emanating from the source. James Lake, Principle Scientist at SRK Consulting presented on the planning and management of residue stockpiles and residue deposits. He noted that ?The proposed amendments require one to determine the leakage rates through barrier systems, but they do not specify acceptable leakages rates. Once the leakage rate is known, one needs to establish how the environment will be impacted as this will differ from site to site.? Also from Jones & Wagener was Riva Nortje, Associate in waste and tailings, who spoke about how to estimate leakage rates through pollution control
barrier systems. She highlighted how leakage rates can be increased by orders of magnitude through uninformed design and specification, poor construction quality control, and operational issues. The importance of competent, experienced specialists determining reasonable leakage rates, and ensuring that the assumptions made in determining such leakage rates are achieved in design, construction, operation and rehabilitation stages was stressed. Dr Heidi Snyman, Technical Director from Golder Associates spoke about source pathway receptor modelling and James Lake from SRK spoke about the regulations that govern planning and management of residue stockpiles and deposits. Also attending the workshop was Albert van Zyl, owner at Terrasim Earth Technologies who discussed unsaturated flow modelling and soil covers for stockpiles. ?The workshop proved to be a great opportunity to gather waste management experts to discuss the implications of the regulations on the mining industry, which makes up over 80% of the waste generated in South Africa per year. We will continue to facilitate learning opportunities like this workshop to grapple with amendments to waste management legislation,? concludes Shamrock.

2 March 2017 (Half day) - GEOSYNTHETIC CERTIFICATION INSTITUTE - INSPECTORS CERTIFICATION PROGRAM (GCI-ICP) EXAM
GIGSA, together with TRI Environmental, proudly hosted several training sessions on Construction Quality Assurance (CQA) from 27 February to 2 March 2017. Attendance varied between 50 and 55 people per day, with attendees from as far away as Botswana. The Irene Country Lodge provided a lovely venue and delectable catering for the week.
The week kicked off on Monday with a primer course on Leak Integrity Surveys/ Assessments (LISA) presented by Abigail Gilson-beck. Abigail heads up TRI?s Liner Integrity Services, is highly experienced in LISA, has worked across the globe, and is clearly passionate about what she does. Her presentations were highly informative and well illustrated from case studies. LISA?s history, leakage and regulatory drivers, statistics, various methods available for use, applicable ASTM codes, and practical considerations were well covered.
Tuesday saw presentations on construction quality
assurance (CQA)/ construction quality control (CQC), by Sam Allen, Vice-President of TRI, as well as Abigail Beck. Sam was his usual entertaining and knowledgable, and not afraid of being contraversial now and again. The day was a good refresher for those experienced in the field, and a speedy introduction to those new to it. The afternoon ended with wedge and extrusion welding as well as site testing demonstrations by Plastiweld. One entrepid engineer trying his hand at wedge welding, and did well. Debate carried on during a cocktail party held adjacent to the dam at the venue. Wednesday was split into two separate sessions: CQA and CQC for compacted clay liner installation before lunch, and CQA and CQC for geosynthetic clay liners (GCLs) after lunch.

years of experience in tailings and waste, presented the lectures on compacted clay liner CQC and CQA. It was apparent that compaction for compacted clay liners is specified differently in South Africa versus eslewhere. GCLs were covered in the afternoon by Sam and Abigail, including the intracacies of testing GCLs in the laboratories, and practical considerations during construction. Thursday was exam day, with 23 people writing the Geosynthetic Certification Institute ? Inspectors Certification Program exam for geosynthetic liners, and 14 for clay liners. Although multiple choice, the exams were certainly no walk in the park, and a 70% pass mark applies to these exams. The overall pass rates for the exams written in South Africa was reported to be
well within GCI?s norms. Well done to all those who made the grade.
Our considerable thanks go to Irene Inan, who was instrumental in course organisation and technical liaison, and to Yolandé van den Berg, who did an impeccable job as the event organiser.

GIGSA/TRI CQA Course Feedback Article
GIGSA hosted the TRI/Environmental, Inc. (TRI) course titled the ?Construction Quality Control and Assurance for Geosynthetics Installations and Compacted Clay Liners? in late February/early March 2017.
TRI has been active in geosynthetics testing, inspection and research and development for 30 years. TRI is an independent, third-party laboratory unaffiliated with any manufacturing, engineering/consulting, or construction management firm.
The course took place at the Irene Country Lodge, Centurion on the 27th February ? 1st March 2017. The material was presented over three (3) days; 2 full days and one half day. CQA course attendees with prior arrangement could sit for the Geosynthetic Certification Institute-Inspectors Certification Program (GCI-ICP) exams immediately following the CQA courses. The full course was attended by a total of 57 delegates, with 24 delegates out of the 57 sitting for the GCI-ICP exam on the 2nd of March 2017. The attendees were from different sectors of the industry, consisting of; consulting engineers, installers, contractors, regulators, third party inspectors, mine owners and project managers.
The few selected feedback received from the attendees on the course material, course presenters and venue can be summarized as follows;
· ?Awesome presentations and material. It broadened my knowledge of geosynthetics?
· ?Great venue and food?
· ?Great presenters, they knew what they were talking about?
GIGSA has further noted suggested areas of improvement on the course as expressed by the attendees in particular to more time allocation for presentations and discussion topics, more case studies and demonstrations on liner integrity surveys. We will work on these for the next CQA course.

HDPE pipe Quality and the Geosynthetics Industry in South Africa.
The Geosynthetics industry specifically, plays a pivotal role in protecting the natural environment from possible contamination and pollution. A huge amount of research, development and design has taken place in this regard to minimise failure and risk.
Invariably in most lining applications, the actual lining is designed to provide drainage points into a piping system. These piping systems incorporate accumulation pots, sumps and manifolds, often manufactured from HDPE. This type of installation is typical for solid waste disposal sites, leachate and gas recovery.
Access to these piping systems once installed and put into use is very difficult indeed. It is for this reason that piping utilised must comply to the highest quality standards available. Pipe failures would necessitate extensive and expansive repairs and could even lead to natural disasters.
In South Africa the reputable pipe manufacturers have adopted ?ISO/SANS 4427 ? Plastic piping systems ? Polyethylene pipes and fittings for water supply?. As an end user - make sure that your pipe has printed on it the mark for ISO/SANS 4427 part 2. This will give you some surety that a quality pipe has been provided. Pipes conforming to this standard are designed for a minimum life span of 50 years.
There are HDPE pipe manufacturers that do not comply with ISO 4427, yet still print the mark. Some pipe manufacturers will have no mark printed on the pipe and term these pipes ?mining pipe? for an example. These pipes comply with no national or international standard, if they did ? the mark would be on the pipe. Accordingly you cannot be sure what quality of product you receive, nor how it will behave under the conditions installed. This pipe could be made from HDPE pipe grade material mixed with blow moulding grade PE, or mixed with Low Density PE. Both ways the product
life span and characteristics are severely compromised. Scientific studies have been done, using the accelerated PENT test (ASTM 1473) to measure resistance to slow crack growth, where virgin HDPE 100 material pipe failed in excess of 2700 hrs, pipe material contaminated with as little as 10 % PE blow mould grade ? failed after 13 hrs. It is for this very reason that ISO/ SANS 4427part 1, S 4.3 refers specifically - Reprocessable material obtained from external sources and recyclable material shall not be used.
The end user should accordingly take all possible steps to prevent purchasing non-compliant pipe, this can be achieved by:
- Ensure that the tender document specifies the pipe quality required and the standard that it should meet.
- The tender document must specify specifically what documentation trail is to be provided with the pipe.
- The tender document must specify what product tests and inspections will be executed, prior to delivery, by a third party independent laboratory.

Geotextile Burst Strength Extreme Performance This video, courtesy of Karl Bester, is the demolition of a 14 story building in the inner city of Pretoria. The site has a higher education building on one side and a heritage church on the other. A NWNP geotextile was used extensively, both as shard capture at detonation points and to protect the university building but most impressively a short time before the blast a curtain of geotextile was raised by two mobile cranes to protect the adjacent church and its stained glass windows from damage. It took 3 seconds from first blast to total collapse into a mound of rubble ? and the adjacent buildings suffered no damage. The blast curtain of geotextile retained rubble and spill, as evident at the toe of the curtain in particular. Watch the demolition.

The SAICE Johannesburg branch Committee (SAICE JHB branch committee), as part of its annual strategy session, identified the need for a platform to celebrate the engineering excellence
that exists amongst our Young Professionals (Professionals who are younger than 35 years of age). It was noted that the Civil Engineering fraternity is very good at taking ownership of their primary responsibility as an agent of social change, but it relatively falls short when it comes to showcasing its achievements. It was also noted that the involvement of Young Professionals at the SAICE branch level left much to be desired and that something needed to be done to remedy this. It was for this reason that the SAICE JHB branch took a decision to establish a forum to address the above mentioned issues, so as to further fulfil its mandate as a branch of SAICE.

SANRAL and SAICE drives the development behind young engineering minds
SAICE hosted the one-day competition at SANRAL?s offices on Saturday (25 March) to afford learners the opportunity of planning, designing, constructing and operating a water distribution network, whereby they encounter similar
challenges that occur in managing an actual water distribution network of a town.
"This competition demonstrates the importance of managing water distribution systems which are important to supply safe and clean drinking water to people. It also exposes the learners to the field of Civil Engineering and provides a glimpse into why Civil Engineers play a critical part in our infrastructure management," said Pieter Joubert, SAICE Algoa branch chairman.

Crushing Cabinet Reshuffle - SAICE speaks out against consequences
The South African Institution of Civil Engineering (SAICE) expresses deep concern on President Zuma?s unwarranted Cabinet reshuffle and the resulting dire consequences on the economy and negative impact on
infrastructure development in South Africa. Seen as an ?honest broker, non-partisan, impartial and unprejudiced voice for the civil engineering profession?, SAICE cannot but act on the strong views expressed by its members in general, and young members in particular, on the removal of competent Ministers and Deputy Ministers and the consequent financial losses.
