Technical Specification of GSE HD HDPE GEOMEMBRANES
GSE HD is a smooth, high quality, high density polyethylene (HDPE) geomembrane produced from specially formulated, virgin polyethylene resin. This polyethylene resin is designed specifically for flexible geomembrane applications. It contains approximately 97.5% polyethylene, 2.5% carbon black and trace amounts of antioxidants and heat stabilizers; no other additives, fillers or extenders are used. GSE HD has outstanding chemical resistance, mechanical properties, environmental stress crack resistance, dimensional stability and thermal aging characteristics. GSE HD has excellent resistance to UV radiation and is suitable for exposed conditions. These product specifications meet or exceed GRI-GM13.

Specification For The Design, Installation Of GSE HD HDPE GEOMEMBRANES
Quality assurance during the design and installation of GSE HD HDPE Geomembrane is critical to the success of the containment system. The surface to be lined should be smooth, free of sharp objects, and properly compacted. All panels must be deployed with adequate overlap and welded using dual-track thermal fusion for long seams, and extrusion welding for patches and details. Non-destructive testing (air pressure for dual-track, vacuum box for extrusion) must be performed on 100% of the seams. Destructive peel and shear testing must be conducted at regular intervals per project specifications.
