GCL overview

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

5 DESIRABLE ATTRIBUTES FOR LINING APPLICATIONS

SWELLS
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.

Bentonite granules transform into a seamless,
monolithic membrane when wetted

3 ITS SELF-HEALING.
When hydrated, bentonite expands and conforms to
irregular surfaces, penetrations, and infiltrates
cracks and voids in concrete.
