Geosynthetic Clay Liners (GCL) Brochure

Geosynthetic Clay Liners are innovative products consisting composites that consist of dry bentonite sandwiched between two layers of geotextile. They are available in a range thicknesses and capabilities that are engineered for a variety of lining applications. Geosynthetic Clay Liners provide an alternative to conventional Compacted Clay Liners by replacing a thick section of compacted clay with a thin layer of pure sodium bentonite. The benefits of this approach include easy installation and more useable air-space in landfill applications.
