Since 1992


Providing innovative new solutions to our customers. Delivering the highest quality of products and services.

CETCO, a wholly owned subsidiary of AMCOL International Corporation, was established in 1991. CETCO is a leader in supplying products and technical expertise to specialized environmental markets. CETCO provides practical solutions to today’s environmental problems. A fullservices, global, environmental company, CETCO is backed by more than 75 years of bentonite mining and manufacturing experience. We are committed to providing quality products that are both cost effective and sensitive to the preservation of the environment.

Accessing AMCOL’s vast supply of mineral reserves throughout the world, CETCO is an established leader in the development of clay minerals technology. Sodium bentonite, formed through the reaction of volcanic ash and salt water many millions of years ago, is a completely natural product, making it an ideal component in many of CETCO’s environmentally-friendly products. CETCO Lining Technologies Group is a leading manufacturer and innovator of Geosynthetic Clay Liners (GCLs). Since 1990, over a billion square feet of Bentomat® and Claymax® GCLs have been installed in numerous projects throughout the world. Our ISO 9001:2000 certified production process creates a product with superior needle-punch density. This equates to the highest internal shear strength in the industry.

Lining Technology Applications:

Liquid Containment: ponds and lagoons, stormwater impoundments, wetlands, canals, secondary containment of storage tanks, wastewater treatment plants; waste containment and closures: landfills, mining facilities, agricultural operations; engineered remedial barriers; erosion control; drainage; ventilation; material separation; cushioning and puncture protection; slurry trenching; sediment and soil capping

Lining Technology Products:

Geosynthetic Clay Liners: Claymax® 200R, Bentomat® ST, Bentomat® DN, Bentomat® SDN, Bentomat® CL, Bentomat® CLT

Sodium Bentonite Soil Sealants: Volclay® CG-50 (granular bentonite), Volclay® CP-200 (powder bentonite), Volclay® TG-50, Volclay® CC-8, Volclay® SG-40

TexDrain® Family of Geonets and Geocomposites: Available in multiple geonet thicknesses; single-sided or double-sided geocomposites in various geotextile fabric weights

Geotextiles: Both non-woven and woven geotextiles in various fabric weights and performance properties

EasyRoller™ Geosynthetic Clay Liner Deployment System: A productivity improvement tool that minimizes manual labor and speeds installation thus decreasing job durations, minimizing potential for employee injuries, and saving money.

Reactive Core Mats™: Needle-punched, aqueous permeable composites of geotextiles
and reactive core materials that reliably adsorb oils and similar organics, heavy
metals, and other inorganic materials from water and contaminated sediment. CETCO
Reactive Core Mats represent a cost effective technological advancement to
traditional methods of contaminant remediation. Using an in-situ approach, Reactive
Core Mats effectively treat and mitigate contaminant migration.

CETCO also manufactures products containing sodium bentonite for a variety of other environmental applications including the drilling of geo-technical monitoring wells and water wells, sealing abandoned drilling holes, and the use in waterproofing buildings and foundations.
