Bentonite Products - Tunneling

Diamond Gel bentonite is a viscosifier, lubricant, and fluid loss control additive that is engineered to disperse easily in poor mixing conditions commonly found on coring rigs, eliminating waste due to clumping.

Our Extra High Yield Bentonite® (EHYB) is a specially peptized high-yield bentonite that disperses and hydrates to provide excellent borehole cleaning capabilities and well-bore stability.

Micro-Gel® is engineered to promote low fluid loss and increased lubricity, which translates to low jacking pressures. The superior filter cake and gel strengths of Micro-Gel® help ensure the integrity of the tunnel walls is maintained.
