About Us

CETCO's Lining Technologies Group is a leader in the field of geosynthetic clay liners and soil sealants. Our Bentomat^® and Claymax^® lines of geosynthetic clay liners (GCLs) are bentonite and geotextile composites engineered for use in a variety of lining applications.

CETCO's GCLs offer several advantages over traditional compacted clay liners - improved hydraulic performance, easier installation and use of less air space within a landfill. Because of their unique self-healing sodium bentonite base, our liners resist cracking that typically occurs in compacted clay liners subjected to repeated freeze/thaw conditions. CETCO's patented manufacturing process utilizes a needle punched technique which encapsulates sodium bentonite between two layers of geotextile, inhibiting migration of the clay in its dry or hydrated state. CETCO's sodium bentonite is used in slurry wall applications.

We also offer chemically treated soil sealants that can withstand contact with both contaminated and uncontaminated water.

The Easy Roller is a patented system designed to improve the productivity of geosynthetic clay liner (GCL) installations.
