Bentonite geosynthetic clay liners for sales

GCL 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. GCL have been proven to provide better engineered performance and durability than several feet of co***cted clay with a total composite thickness of less than one quarter of an inch.

About the clay material, it is usually bentonite, which sandwiched between two layers geotextiles.
This lining mechanism is mechanically bonded by needle punching from one nonwoven geotextile through the bentonite to the other nonwoven or woven geotextile.

The bentonite swells and extrudes through the geotextile fabric at the overlap, forming a seal by
producing a dense and uniform clay barrier with the same hydraulic qualities in all parts of the
clay liner

Bentonite is a natural clay formed by weathering of volcanic ash. Its chief constituent is the clay mineral montmorillonite. Bentonite is distinguished from other clays by its extreme fineness,highly absorbent nature and curious property of swelling in water.

Properties:

GCL not only have all the characteristics of geotextile material, but also has excellent

water (seepage) performance.
