Introduction:geosynthetic clay layer(GCL) is a waterproofing material,made of compound geotextile,non woven geotextile with expansion bentonite in the center.It is specially used in artificial lake,landfill,underground garage,roof garden,tank,oil depot and other chemical yard.There are many small fibre space in GCL after being needle punched,then the bentonite powder can not more in one direction,so when meeting water,it will become a high density waterproofing layer and stop water leakage efficiently.
Specification: GCN-NP,needle punched GCL; GCL-OF,needle punched GCL coated with film;GCL-AH adhensive GCL.Unit weight: ≥4000g/㎡,width: 4～6m.
Feature:compaction, permanent waterproofing, ineffective to temperatureIt will not be crack under low temperature, environmental:bentonite is nature inorganic material,nontoxic to human,no special request to environment,it is environmental friendly.
Application: municipal projects, subway,underground project of buildings and waterproofing in roof water tank,environmental project,lanfill,sewage treatment,industrial waste material, waterproofing of gardens artificial lake,golf ground pond,anti-seepage of petrification,mine area.
