Detailed introduction
Geosynthetic Clay Liner(GCL) is a new type of geosynthetic materials. It is mixed by a natural grading sodium bentonite particles and corresponding admixture as raw material, through the acupuncture technology and equipment, fixed bentonite particles between geotextile and plastic woven cloth and blanket to be maded of. Bentonite waterproof carpet has all the characteristics of geotechnical material, but also has excellent waterproof performance (permeability).
Bentonite waterproof carpet according to the production process can be divided into: acupuncture method of sodium base bentonite waterproof carpet, acupuncture effect of sodium base bentonite waterproof blanket and sodium base bentonite waterproof carpet adhesive method.
Sodium based on bentonite waterproof carpet as a new type of ecological environmental protection、composite 、impervious material, with its unique performance of seepage prevention is widely used in water conservancy, environmental protection, transportation, railway, civil aviation, civil engineering, etc. specific used in the basis of the landfill treatment and caps, artificial lakes, reservoirs, channels, rivers, roof garden of anti-seepage, basement, subway, tunnel, underground passage, seepage of underground buildings and so on.
Performance
