1. What Is High Density Polyethylene Pond Liner?

A High Density Polyethylene (HDPE) pond liner is a geomembrane made from high-grade polyethylene resin, combined with additives like carbon black (2–3%), antioxidants, and UV stabilizers, to create a robust, impermeable barrier for water containment. HDPE liners are produced through a three-layer co-extrusion process, ensuring uniform thickness (0.3–3.0 mm) and high tensile strength (15–20 MPa), per ASTM D412 standards. With a density of 0.94–0.96 g/cm³, HDPE liners offer superior puncture resistance (2.5–3.5 kN) and low permeability, making them ideal for preventing seepage in ponds, reservoirs, and industrial containment systems. According to BPM Geosynthetics, HDPE liners are used in 70% of global water containment projects due to their ability to withstand temperatures from -70°C to 110°C and resist chemicals like acids and alkalis in 90% of applications.
