Bentonite Gcl Clay Liner Bentonite Blanket Waterproof Blanket
Bentonite Gcl Clay Liner Bentonite Blanket Waterproof Blanket
Product Description
GCLs are high performance environmental liners comprised of a layer of lowpermeability sodium bentonite combined with geosynthetic carriers, such as woven and/or nonwoven geotextiles, and in some cases polymer geomembranes. GCLs have been proven to provide better engineered performance and durability than several feet of compacted clay with a total composite thickness of less than one quarter of an inch.

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
