Are Poly-Flex liners immune to root penetration?
Poly-Flex liners resist root penetration. However, some vegetation, such as nut grass, could penetrate the liners. We recommend that the subgrade soils be prepared to be free of roots and organic material. • Are Poly-Flex liners immune to attack by rodents? Poly-Flex liners are generally immune to rodent and insect attack because they contain no plasticizers or scrim source proteins, which are sometimes present in other synthetic liners. • 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 th
