At the slurry plant, cement, or some other setting agent, is added to the bentonite slurry. The viscosity of the mixed slurry is designed to be in the fluid range during the excavation process. The slurry is then pumped from the mix plant to the excavation. Once the excavation is to full depth, the bottom is cleaned and the process moves on.

Bentonite is an off-white montmorillonite clay formed from altered volcanic ash. it has a sheet-silicate structure and is especially notable for the way in which it absorbs and loses water and for its base-exchange properties. sodic bentonite can absorb up to 10 times its own weight in water and can swell to 18 times its dry volume.
