Geomembrane BENTOMAT® CL

BENTOMAT® CL is a Composite Laminate reinforced GCL consisting of a layer of sodium bentonite between two geotextiles, which are needlepunched together and laminated to a thin flexible membrane ranging from 5 to 60 mils. CETCO products are the only GCLs that offer Supergroove technology, a groove in the nonwoven fabric that allows the bentonite to migrate out and self-seam at the overlap. This feature eases the installation process by eliminating the need for supplemental bentonite. All CETCO geosynthetic clay liners feature granular bentonite, which creates less dust during installation than powdered bentonite and is more likely to stay in place once deployed.
