CETCO markets geosynthetic clay liner (GCL) products under the BENTOMAT® and CLAYMAX trade names for lining and capping landfills, encapsulation of contaminated land, lining of ponds, lagoons and canals, and secondary containment purposes.

GCLs are a natural extension of CETCO's core capabilities. CETCO is firmly committed to the development and advancement of technologies that integrate bentonite and geosynthetics. This commitment to innovation is the foundation for CETCO's GCL product line.

CETCO GCLs provide hydraulic performance equivalent to one metre of compacted clay, with a total thickness of less than 10mm. CETCO GCLs are self sealing if punctured and are manufactured in large rolls that require just a simple overlapped seam. Fast and easy to install, as well as being highly cost effective, CETCO GCLs provide a superior choice for both designers and contractors.
