Pitched*

Pitched is similar to naturally quarried and dressed stone. It has a rough raised profile that produces the subtle, authentic rugged appearance of traditional tooled stone found in many Limestone and Sandstone areas.

Split

Split has a slightly uneven finish to its face which looks similar to rough hewn stone. It can be laid in either a coursed pattern or to create a more authentic appearance use two or more course height blocks.

Tumbled

Tumbled has a rough irregular shape and finish that replicates old weathered stone. It is especially popular in rural areas.

Our reconstituted stone and concrete products contain natural aggregates and pigments that can vary slightly in colour from to time to time. We therefore cannot guarantee that manufactured products from different production batches will always have identical colouration. Therefore we advise that when using several packs of walling on a project, that the product is drawn randomly from all of the packs used to achieve an overall well blended appearance.

Bekstone walling is available in a variety of colours, course heights and lengths to match most stone requirements and offers three types of finished textures.

A premium natural product that looks authentic, attractive and delivers high levels of durability. Readily accepted by urban and rural planning authorities, the range offers a cost effective alternative to other cladding and building materials.

All products are 100% recyclable and are manufactured in accordance with BS EN 771-5, ISO 9001 quality management & ISO14001 environmental management. Bekstone has been awarded BREEAM A* environmental profiling.

Technical Data

Composition

All products are manufactured from accurately controlled proportions of milled limestone, cement and pigments. The products are manufactured from natural materials and may be subject to slight colour variations. It is therefore recommended that users work from 3-4 packs to achieve optimum colour blending.

Weathering

Many factors influence weathering characteristics, such as location, degree of exposure, prevailing weather conditions and design. Bekstone Walling will weather in a similar manner to natural stone. Bekstone will not be held responsible for the apparent colour fading or any other effect on the appearance of the stone due to efflorescence. This is a temporary phenomenon characteristic of all high cement content products which will reduce over a period of time.

Water Absorption

As with all facing masonry (reconstituted stone, bricks and natural stone) the external envelope is not totally impervious to heavy driving rain as there is the possibility that water penetration will take place through mortar joints. To avoid this good building and site practice should be observed. Tests carried out gave a mean average of less than 10% absorption by weight after 24 hours.

Movement Joints

Consideration must be given to the inclusion of movement joints. These should be installed wherever there are changes in height, wall thickness and not greater than 6 metre centres of continuous walling. Bed reinforcement should be included above and below openings extending at least 600mm either side of the opening.

Mortars

We strongly recommend the use of mortars containing lime because their lower permeability gives greater resistance to rain penetration. Cement : Lime : Sand = 1:1:6 Masonry Cement : Sand = 1:4 Plasticised Cement : Sand = 1:5-6

Random Mix

Supplied in the following approximate course height ratios:

30% 65mm, 60% 140mm, 10% 215mm

In keeping with our policy of continual product development, Bekstone reserves the right to alter any specification shown. All products are made from naturally occurring materials and as such, colours depicted are as accurate as photographic and printing process allow. All content is for guidance only with weights and measures being approximates. All recommendations and suggestions made do not constitute a guarantee.
