rawMAT Bentonite

The rawMAT Pre-hydrated Bentonite system provides high level waterproofing protection to below ground structures in the most demanding situations.

The advantage of our pre-hydrated bentonite system is that the initial bentonite hydration occurs under factory controlled conditions. Unlike the dry bentonite systems, which are prone to shrinkage and cracking, the Rawmat Pre-hydrated bentonite is highly resistant to the effects of water contaminants. These contaminants induce cationic exchange in dry bentonite systems causing them to have a reduced swell, shrink and crack as the clay converts from sodium bentonite to the calcium form.
