The Berm Ground Liner is crafted from a premium high-density polyethylene (HDPE) geomembrane using specially formulated virgin resin. This formulation, consisting of 97.5% polyethylene, 2.5% carbon black, and a small amount of antioxidants and heat stabilizers, delivers exceptional performance without any additional additives or expansion agents. It offers outstanding chemical resistance, mechanical strength, dimensional stability, and resilience to environmental stress cracking, heat aging, and UV exposure, making it ideal for outdoor use.
