Geosynthetic Clay Liner

タイトルまたは説明

Geosynthetic clay liners (GCLs) include a thin layer of finely-ground bentonite clay. When wetted, the clay swells and becomes a very effective hydraulic barrier. GCLs are manufactured by sandwiching the bentonite within or layering it on geotextiles and/or geomembranes, bonding the layers with needling, stitching and/or chemical adhesives. GCLs are commonly used to augment or replace compacted clay layers. Geosynthetic Clay Liners are mainly used in the following applications: * waste and contaminated soil caps and closures * landfill base liners * geomembrane protection layers * gas and vapour seals * surface impoundment liners * secondary containment * dams, canals, and water courses * tailings containment * groundwater protection * sorptive barriers * vertical barriers
