Geosynthetic Clay Liners

Geosynthetic Clay Liner Products & Specification

Geosynthetic clay liners (GCLs) are most commonly used for landfill and mining applications to prevent leachate contamination into the surrounding environment. GCLs are heavy duty factory manufactured hydraulic barriers. They consist of a layer of Bentonite or similar very low-permeability material that is supported by geotextile fabric or geomembranes that are mechanically bound together by stitching or chemical bonds.

Environmental laws in the UK and around the world dictate that any drainage water or seepage from landfills must be contained, collected and disposed of correctly to prevent contamination. This is essential to prevent local ground water from potential environmental or ecological damage.
