What procedures should be followed for storing Poly-Flex liners at a jobsite?
Poly-Flex liners should be stored on a prepared ground that is free of rocks, roots, debris, or materials that may damage the liner. The rolls should also be stored away from standing water and should not be stacked more than two rolls high. • How much liner is normally installed and tested in one day? The amount of liner that can be installed and tested in one day depends upon site conditions, subgrade preparation and the difficulty of the project. • Why do Poly-Flex liners have wrinkles? Polyethylene liners expand and contract as the sheet temperature changes. This thermal expansion/contraction will cause the liner to grow or shrink with variance in temperature. • What is the cold temperature resistance of Poly-Flex liners? Poly-Flex liners pass the low temperature brittleness test at -70° C (-94° F) according to the ASTM D 746. • Are there any ambient and/or sheet temperature limits when welding? The industry standard is a maximum of 104°F measured 6 inches above the liner surface a
