Patent abstract
A method of forming in-situ pilings in clay soil. An auger stirrer is rotatably and axially forced into the ground. Water, dry binder (cement/or lime), and air are injected to lubricate the tool, and liquify the mix of clay soil, binder and air to form a uniform structure, most of the air percolating from the mix before it hardens.
