Product Description
Geosynthetic clay liners (GCLs) is a special waterproofing material, made of woven geotextile, non-woven geotextile with swelling sodium bentonite in the center. It is main used in man-made lake, landfill, underground garage,roof garden, pond and other chemical storage yard. A lot of tiny rooms will be formed in GCLs after being filled by bentonite and needle punched, then the granular or powder of bentonite can not move in any direction, so when meeting water,it will become a high density waterproofing layer and cease water leakage efficiently.
Applications
● Landfill project
● Natural water landscape project and man-made landscape project
● Underground tanker project
● Reservoir (pool) impervious project
● Canal anti-seepage project
● Subway project
● Tunnel project
● Underground structure and foundation waterproof project
Characteristics
● Sodium-bentonite can form a high density isolated layer quickly after meet water, its permeability coefficient is less than αx10-10 m/sec(α=1-9) when when its thickness up to 3mm,almost equal 750px of clay.
● Because sodium-bentonite is a type of natural mineral, so that the GCLs don't lost its special peroperty because of environment changed or long time installed, also don't bring any side-effect to environment..
● GCLs is very easy for installing and does not need heating and adhesive at website, only need bentonite powder and nails/steel chips for fixing etc.
● GCLs can be used at wide temperature range.
