CETCO is a wholly owned subsidiary of the American Colloid Company, the largest and oldest bentonite mining and manufacturing company in the world. Increasingly stringent federal, state and local environmental regulations prohibit groundwater contamination. Volclayâ and Bentomatâ are CETCO's sodium bentonite-based products for pond, lagoon and landfill lining applications.
Colloid Environmental
Technologies Company's (CETCO) patented chemical treatment processes produce
specialized Volclay soil sealants for use in both contaminated and
non-contaminated water conditions. Volclay is a sodium bentonite which swells
to a volume 10-15 times its dry-bulk state producing a greater volume than
natural clay or other bentonites. Volclay is infinitely reusable by drying and
re-swelling with fresh water.
