Waterproof Blanket Geosynthetic Clay Liner For Artificial Lake Lining
Product Description
It is composed of 3 levels. The upper level and the lower level are woven geotextile and non woven textile.
The middle level is bentonite grains, which are carefully selected crude and filled in between the two levels after special processing.
This GCL is a kind of new green waterproof materials, which are widely applied in many waterproof construction projects.
GCL can be applied separately, or combined with high density polyethylene (HDPE)

Advantage Bentonite Mat Clay Liners
1. An economic and environmentally sound alternative to synthetic liners or to bituminous products.
2. Dense and slim with high bond and shear strength.
3. Superior to conventional compacted/puddled clay lining
4. High puncture and tear resistance - the bentonite clay has a high swelling capacity and low permeability
offering good system integrity.
5. Self-sealing.
6. Long-term protection against ground water seepage
