It was formed hundreds of millions of years ago through the aqueous deposition of volcanic ash. Bentonite is an ore whose main ingredient is the clay mineral named montmorillonite. WHAT IS BENTONITE?

5 DESIRABLE ATTRIBUTES FOR LINING APPLICATIONS BENTONITE

#1: IT WHEN WETTED Bentonite swells up to 15 times its original volume if unconfined; a swell potential force exists when confined. This makes bentonite an active barrier. SWELLS

Expanding Bentonite Platelets

#2: IT SEALS WHEN WETTED Bentonite granules transform into a seamless, monolithic membrane when wetted: 3. Seamless Bentonite Membrane TIME SEQUENCE PHOTOGRAPHY—CLAYMAX 1. Installed dry 2. Granules transform when wetted

#3: IT’S SELF-HEALING. When hydrated, bentonite expands and conforms to irregular surfaces, penetrations, and infiltrates cracks and voids in concrete.

#4: IT’S “GREEN” Non-toxic NSF certified FDA certified No volatile organic compounds (VOCs) Used in toothpaste, skin lotions, soap, pharmaceuticals, cattle feed, even used to filter fine wines and fruit juices

#5: PROVEN TRACK RECORD 20 years of successful performance Hundreds of millions of square feet installed worldwide via installation companies, geosynthetics suppliers, and GCs. Technical assistance available in over 40 countries

CETCO is the only GCL manufacturer that produces its own bentonite Superior knowledge of bentonite chemistry and performance Total control over bentonite quality No limits on production capacity
