POND LINING

Definition: The installation of an impermeable barrier on the base and sidewalls of artificial containment areas, such as reservoirs, retention ponds, lagoons, or industrial waste pits.

Core Function: To prevent contained water from seeping away into the ground, or conversely, to stop hazardous liquids (like industrial effluent) from contaminating the surrounding groundwater.

How it Works: It creates a highly durable, watertight basin that serves as an absolute barrier between the stored liquid and the natural subsoil below.
