Our HDPE geomembrane is produced from virgin high-density polyethylene resin with carbon black and stabilizers, delivering a durable, chemically inert barrier for liquid and gas containment. The smooth or textured sheet is weldable by dual-hot-wedge or extrusion methods and keeps stable performance from -40°C to +60°C.
