Garware's Geosynthetic Clay Liners (GCLs) are highly effective hydraulic barriers that are designed to provide superior containment and control of fluid migration in geotechnical engineering projects. These factory-manufactured liners consist of a layer of bentonite or other low-permeability material that is supported by geotextiles and/or geomembranes.

The layers of the GCL are mechanically held together by a combination of needling, stitching, or chemical adhesives, creating a highly durable and effective barrier. Garware's GCLs are constructed to withstand harsh environmental conditions and are highly resistant to punctures, tears, and chemical degradation.
