Geosynthetic Clay Liner (GCL) is a composite material consisting of two layers of geotextile with bentonite wrapped in the middle. It combines the high strength of geotextile and the excellent anti-seepage performance of bentonite. It has the advantages of excellent anti-seepage performance, convenient construction, strong self-healing ability, etc. It is widely used in anti-seepage projects such as landfills, tailings ponds, and artificial lakes.
