GCL(Geocomposite Geosynthetic Clay Liner)
Description :
Geosynthetic clay liners (GCLs) are high performance needle punched environmental reinforced composites which combine two durable geotextile outer layers with a uniform core of natural sodium bentonite clay to form a hydraulic barrier. Fibers from the non-woven geotextile are needle punched through the layer of bentonite and incorporated into the other geotextile (either a woven or non-woven).when hydrated under a confining load, the bentonite swells to form a low permeability clay layer with the equivalent hydraulic protection of several feet of compacted clay.
Specification:
Geonet thickness: 5-8mm; Width: 2-4m; Length as requested
Geotextile can be needle punched polyester geotextile, continuous filament PET nonwoven geotextile or Polypropylene nonwoven geotextile, and the unit weight normally 200g/m2.
Features:
1. Excellent drainage function, able to bear long time high pressure load
2. High tensile and shear strength
3. Able to protect its long time and stable hydraulic conductivity
4. Able to bear more than 2000kpa compression load, its anti-pressure capacity much higher than common drainage network
5. Corrosion resistant, acid and alkali resistant.
Applications:
Seepage proofing, anticorrosion, leaking stoppage and reinforcement
1. Municipal engineering, underground construction of subway, buildings as well as the roof tank.
2. Environmental sanitation, solid waste landfill, sewage farm, industrial waste
3. water conservancy, lake, river, dam and reservoir.
4. Garden and park, artificial lake and golf cause pool.
5. Petrochemical engineering, mining industry and agriculture engineering
