HDPE & LLDPE Geomembrane Liners are impermeable geosynthetic barriers manufactured from high-quality polyethylene resins. HDPE offers high stiffness, excellent chemical resistance, and long-term durability, while LLDPE provides greater flexibility and elongation for improved conformity to subgrade conditions. Both are designed to deliver superior containment, seepage control, and environmental protection, and are widely used in landfills, ponds, reservoirs, wastewater treatment facilities, mining, and industrial containment applications.
