Are there any adhesives, tapes or glues that are suitable for joining Poly-Flex liners?

There are no adhesives, tapes or glues that provide a permanent, watertight bond to polyethylene. • Can Poly-Flex liners of different thickness or textures be welded to each other? Yes. Poly-Flex liners with thickness or texture differences of 20 mils or less can be fusion welded together. Liners with thickness or texture differences of greater than 20 mils should be extrusion welded together. • Can Poly-Flex liners of different densities be welded to each other? Yes. Welding temperature adjustments must be made to achieve a successful weld. When extrusion welding, the lower density welding rod should be used. • What are the advantages of LLDPE over PVC geomembrane? The advantages are as follows: • LLDPE has resistance to a wider range of chemicals as compared to PVC. • LLDPE is immune from biological attack by microorganisms. Microorganisms could attack PVC and use the plasticizer as a source of food. • LLDPE is resistant to burrowing animals, PVC is not. • LLDPE has a lower ...  more
