Produced from high-density polyethylene (HDPE) with a textured surface on one or both sides, created via nitrogen gas injection during the blown-film extrusion process. The engineered surface texture enhances frictional contact with adjacent soil layers.
Specifications: Thickness 1.0mm-3.0mm · Width up to 7m · Compliant with GRI GM13 standard · Friction angle >= 26 deg
Applications: Steep-slope landfill liners, surface impoundments, canal linings, and tailings dams where slope stability is critical.
Key Advantage: The textured surface significantly increases friction coefficient, preventing liner slippage on inclined surfaces and enabling steeper slope designs.
