What Is Pond Lining & Water Storage Material?
Pond lining and water storage systems are protective membranes used to prevent water seepage into soil. They are essential for fish farming ponds, irrigation reservoirs, garden ponds, industrial water containment, wastewater treatment systems, and other applications where long-term waterproof integrity is required. DERFLEX produces pond liners using reinforced PVC, HDPE, LLDPE, and multi-layer composite fabrics for improved tear strength and weatherability.
