What method is used for joining Poly-Flex liner panels together?
Poly-Flex liner panels are joined by two methods. The primary method of welding geomembrane panels together is fusion welding. In fusion welding, heat is applied directly to the geomembrane panels by a motorized hot wedge welder. The panels are then routed through a series of rollers that fuse the material together. The second method of joining Poly-Flex Liner panels is extrusion welding. This method is used primarily for performing repairs on the liner material. This method utilizes the application of molten polyethylene welding rod to the surface of the two geomembrane sheets to be joined. The molten extrudate creates a bond that seals the two pieces of geomembrane together. • 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
