Geosynthetic Clay Liner (GCL) – Waterproofing & Containment System
The Geosynthetic Clay Liner (GCL) is a high-performance hydraulic barrier made from a layer of natural bentonite clay encapsulated between geotextile layers. It functions as an effective waterproofing system with very low permeability, preventing the seepage of liquids and contaminants. Widely used in landfill lining, ponds, and containment systems, GCL provides a reliable and environmentally safe solution for soil and water protection.
