Introduction of Bentonite Waterproof bentonite blankets (GCL)，GCL is a kind of impervious liner between CCL (on-site thick compacted clay impervious liner) and polymer material --- geo-membrane. It is mainly used in waste landfills, groundwater reservoirs, underground infrastructure construction and other projects in environmental engineering to solve the problems of sealing, isolation, and anti-leakage.
Geosynthetic Clay Liners ，clay blanketsis called bentonite composite waterproof blanket (GCL), also known as bentonite waterproof blanket, waterproof mat, GCL waterproof mat and other bentonite composite waterproof blanket (GCL) which is a new type of geosynthetic material. It is a blanket waterproofing membrane made by mixing the natural sodium-based bentonite particles and the corresponding admixtures into raw materials, and fixing the bentonite particles between the geotextile and the plastic woven fabric through a needle punching process and equipment. The bentonite waterproof blanket has all the characteristics of geotechnical materials and excellent waterproof (permeability) properties.
