Environmate Geosynthetic Clay Liners

Geosynthetic clay liners (or gcls) are the newest subset within geosynthetic materials. They are rolls of factory fabricated thin layers of bentonite clay sandwiched between two geotextiles or bonded to a geomembrane. Structural integrity is maintained by needle punching, stitching or physical bonding. They are seeing use as a composite component beneath a geomembrane or by themselves as primary or secondary liners.
Features:
1) a needle-punched reinforced geosynthetic clay liner (gcl)
2) uses two geotextile layers to encapsulate a layer of natural sodium bentonite
3) the needle-punched fibres transmit shear forces through the bentonite core
4) used as a sealing barrier against liquids and gases in various civil and environmental applications
