GPS Diamond Scrim 30, 36, 45 mil- Heavy Duty LLDPE Liner

GPS Diamond Scrim is composed of two heavy sheets of impermeable, high strength LLDPE extruded on both sides of a high tensile strength scrim-reinforcing layer. This composite membrane has an excellent combination of flexibility and tensile strength. Its optional gray upper surface reduces heat buildup compared to a standard black material and is less reflective than a white liner in bright environments. The opaque black underside of the liner prevents sunlight penetration and UV transmission. Raw materials are produced 142” in width to minimize the seams required.

EPA Regulations enacted in May 2015 require the use of geomembrane liners and caps for the disposal of coal ash. GPS geomembranes meet or exceed GRI GM13 and GM17 standards and are available in large rolls to expedite deployment. We also offer interim covers and lightweight rain-shed covers, fabricated to any size.

An optional textured surface improves traction and increases friction for improved slope stability and onsite safety.

(1)Alternatively, an acceptable ply adhesion is to have a film tearing bond occur within the sheet material.
(2)The Manufacturer has the option to select either one of the OIT methods listed to evaluate the
antioxidant effectiveness in the geomembrane.
(3)Roll widths and lengths have a tolerance of +/- 1%
