Geosynthetics clay liner ( GCL) is made of natural sodium-based bentonite or other low-permeability mineral materials covered with two layers of geosynthetics such as geomembrane or geotextile, which are fixed together by needle punching, sewing or chemical adhesives. Environmentally friendly and ecological composite geotechnical materials. Geosynthetics clay liner ( GCL) is a new type of geosynthetic material, which is widely used as a substitute for compacted clay liners. The bentonite in the inner layer of the Geosynthetics clay liner ( GCL) can swell and automatically form a low-permeability clay layer when it meets water, which plays the role of moisture-proof and waterproof. The excellent anti-seepage performance of Geosynthetics clay liner ( GCL) combined with the excellent tear resistance, high tensile strength, corrosion resistance, acid and alkali resistance of geotextile or geomembrane, make bentonite waterproof blanket adapt to special environmental requirements and achieve ideal anti-seepage effect.

Features of Geosynthetics clay liner ( GCL):

Excellent anti-penetration performance

Ripstop

high tensile strength

preservative

Wide temperature range applicability

Strong Acupuncture Reinforcement

high shear strength

Easy construction

Application of Geosynthetics clay liner ( GCL):

As a new type of environmentally friendly composite geotechnical material, Geosynthetics clay liner ( GCL) has excellent tensile strength and chemical stability of geotextile or geomembrane and low permeability of bentonite. 

It is widely used in landfills, mining, dams, canals, lakes, environmental protection , Artificial lakes and underground waterproofing and anti-seepage projects of buildings.
