How are Poly-Flex liners held in place on side slopes?
The most common method of securing the liners on side slopes is by means of an anchor trench around the perimeter. The batten strip or the PEC embed channel systems are used to attach the liner to structures. Please refer to the Poly-Flex Design Details located in Technical Information • How steep can side slopes be designed for Poly-Flex lining applications? The side slopes can be designed as steep as 90° or a vertical wall. • Should Poly-Flex liners be used as reinforcement (structural) membranes? No. Poly-Flex geomembranes are not reinforced materials and should not be used as structural membranes to carry loads. • What are interface friction angles? Interface friction angles express properties relating to sliding shear resistance between two materials facing each other. This property is used in stability calculations to design a stable liner system. • How are interface friction angles determined? The industry standard test method is the ASTM D 5321 “Determining the coefficient of s
