A pond liner is a durable, impermeable sheet—typically made from materials like HDPE, LDPE, EPDM, or PVC—used to create a barrier that prevents water from leaking into the soil. It forms the base and sides of artificial ponds, reservoirs, fish farms, and other water storage structures.
Pond liners work by providing a continuous, watertight layer that blocks water seepage. Unlike natural soil, which can absorb and drain water, these liners do not allow liquid to pass through. As a result, they help maintain consistent water levels, reduce water loss, and protect the surrounding soil from erosion. Additionally, they enhance the longevity and performance of water bodies, making them essential in agriculture, aquaculture, landscaping, and environmental applications.
