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 soil and geosynthetic or geosynthetic and geosynthetic friction by the direct shear method”. • What are the advantages of Poly-Flex textured liners? Our blown-film textured liners have smooth edges and are covered by U.S. Patent Nos. 5,763,047 and 5,804,112. The blown-film texturing provides increased friction angles for higher stability on steep slope applicat
