Product Description

GCLs Bentonite Waterproof Blanket Mat for Earth Work Landfill and Geosynthetic Clay Liner Product

GCLs are high performance environmental liners comprised of a layer of low-Permeability sodium bentonite combined with geosynthetic carriers, such as 

woven and/or nonwoven geotextiles, and in some cases polymer geomembranes. 

Geosynthetic clay liner, also know as geo clay liner or GCLs,  is made from natural sodium-based bentonite or other low-permeability mineral materials covered with two layers of geosynthetic materials such as geomembrane or geotextile by needle punching, stitching or strong fixation with chemical adhesives. Geosynthetic clay liner (GCL) is an environmentally friendly composite geotechnical material widely utilized as a substitute for compacted clay liner. It consists of a layer of bentonite that can swell and form a low-permeability clay barrier when exposed to water, providing moisture-proof and waterproof properties. The combination of outstanding anti-permeability characteristics in GCL, along with the tear resistance, high tensile strength, corrosion resistance, and acid and alkali resistance of geotextile or geomembrane, enables GCL to meet specific environmental requirements and achieve an ideal anti-seepage effect.
 

GCLs have been proven to provide better engineered performance and durabilitythan several feet of compacted clay with a total composite thickness of less than one quarter of an inch.

Product Features
1. Good waterproof capacity, sodium bentonite can form a gel layer which does not permit the penetration of water
2. It has strong ability to fit the uneven sedimentation well.
3. Good water-keeping and self-fix capacity
4. Permanent waterproof capacity, sodium bentonite is natural inorganic mineral material, there is no corrosion and age happened to sodium bentonite
5. Sodium bentonite is harmless to human being and environment.
6. Easy operation, it can be fixed in nail and gasket, it can reduce the building time greatly.

• It was possible to order the exact length of liner required across the channel to be supplied on one roll. This eliminated the need to 'cut and paste' the liner.
• The material is suitable for sites where no clay source was available..

GCL is the material of choice for primary or secondary containment in 

composite landfill cells and closures, mining leach pads, tailing 

impoundments and reclamations, and pools and lagoons.
