Can Poly-Flex liners be installed directly on top of concrete slabs or asphalt pavement?
Yes. Concrete and asphalt slabs must be smooth and have no sharp edges. • Can Poly-Flex liners be attached to fixed structures such as concrete, steel, pipes, etc? How? Yes. Poly-Flex liners can be attached to fixed structures through a number of methods. With concrete structures, two methods are preferred. The first, to be used in new structures, is the Poly-Flex polyethylene embed channel (PEC). This channel can be inserted into a new concrete structure, providing for a three inch HDPE surface to which Poly-Flex liners may be welded creating a watertight seal. Secondly, Poly-Flex liners may be attached to new and existing concrete structures through the use of stainless steel or aluminum batten strips. These strips are attached to the concrete by inserting stainless steel anchor bolts into the concrete, placing the geomembrane liner over the anchor bolts, placing a strip of neoprene gasket between the liner and batten strip, and securing the batten strip with washers and nuts.
