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.
