The ChemGrout CG-550B bentonite well grouter series are skid mounted units.
A large 45-gallon (170 liters) baffled mix tank is equipped with an efficient paddle mixer that blends bentonite and polymer/bentonites quickly and completely.
These units feature a Bowie gear pump that gently pumps the polymer bentonites, allowing the critical time needed to place the material within the cavity.
