GCL are high performance environmental liners comprised of a layer of low permeabilitysodium bentonite combined with geosynthetic carriers, such as woven andlor nonwoven geotextiles, and in some cases polymer geomembranes. GCL 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.GCLcan form many small fiber space, make the bentonite particles can't flow in one direction, when under the influence of water within the mat forming uniform density of colloidal waterproof layer, prevent the leakage of water. For different projects,it can combine HDPE liner for better waterproof

Specification

Product Description 

Geosynthetic clay liners (GCL) consist of clay material and geotextile.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.

Characters

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.

Application fields:

landfill caps 

base liner applications under roads, railways,

containment for ground tank farms, dams, canals, ponds, rivers and lakes.
