Waste Containment

Meeting the need for Waste Containment applications of all types

CETCO GCLs have been used in a wide variety of waste containment applications throughout the world. Our global technical support, sales, manufacturing and logistics allow us to serve projects of all types in any location.

Landfill liners and caps

GCLs serve as the clay component of composite lining systems used in industrial, hazardous and municipal solid waste landfills. They may be used alone or in combination with a geomembrane in a composite cover system, GCLs provide significantly lower permeability, improved ease of installation, an increased amount of usable space when compared to traditional compacted clay liners.

Highway and civil

GCL are used in highway and civil applications such as at airport de-icing facilities. CETCO GCLs are compatible with de-icing fluid (glycol diluted 50/50 with water). GCLs can also be used to line roadway drainage swales for containment and to prevent excessive percolation, minimizing potential for groundwater contamination.

BENTOMAT® DN

BENTOMAT® DN is a reinforced GCL consisting of a layer of sodium bentonite between two nonwoven geotextiles, which are needlepunched together. 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.
