ABSTRACT:
In forming foundation piers in the earth, a slurry of earth support material such as bentonite clay is mixed under high shear mixing conditions and introduced into the hole as drilling thereof progresses to provide lateral support for the side walls of the hole. Plastic concrete is then injected into the hole, displacing the slurry upwardly until the hole is filled with concrete to the desired level.
The slurry may be recovered for reuse in drilling and forming another foundation pier.
