ABSTRACT:
A method of improving, for building purposes, soft ground containing organic material utilizes a fluid composition, for injection into the ground, consisting of cement, water, bentonite and either sand or a lightweight, inert, finely divided, readily available naturally-occurring material such as volcanic ash, or an industrial or agricultural waste such as coal or incinerator ash, wood dust, powdered waste plastics material, cereal hulls or the like. The composition is injected at prescribed locations to effect replacement of portions of the soft ground and solidifies in situ, while because of the resulting pressure created on the surrounding ground soil water is expressed and the surrounding soft ground becomes compacted.
