A dam liner (also called a pond liner or geomembrane) we have HDPE and PVC is a waterproof sheet used to line ponds, dams, reservoirs, canals, and water storage structures to prevent water from seeping into the ground.
HDPE (High-Density Polyethylene): Strong, durable, UV-resistant, and the most commonly used for farm ponds and dams.
PVC (Polyvinyl Chloride): Flexible but generally less durable than HDPE for outdoor use.
