Introduction :
GCL are the newest subset within geosynthetic materials.they are rolls of factory fabricated thin layers of bentoniteclay sandwiched between two geotextiles or bonded to a geomembrane.
Applications:
1.GCL mainl used in environmental engineering in the waste landfill
.beneath a geomembrane in the primary liners of a landfill
.beneath a geomembrane in the secondary liner of a landfill
.beneath a gromembrane in the cover of a land fill
2.underground reservoirs
3.GCL can be as a single liners for canals
4.Above geomembranes as puncture protection against coarse gravel
5.As a protion of a compacted clay liner in primary and secondary composite liners.

Features:
1.Improved leakage performance
2.permanent waterproof performance
3.simple construction
4.Not influenced by air temperature
5.A kind of green material and good to environmental protection.
6.More versatile than compacted clay
7.Increased airspace and liner efficiency
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.
