ABSTRACT:
A method to make an in-situ piling in which a dry binder and water are injected into the situs of an intended piling. A rotary tool is inserted into the soil which as it descends into the situs and exits it, mixes the soil, binder and soil along with the air used to inject the binder, reducing the size of binder particles and rendering the resulting mixture sufficiently fluid that much of the air can percolate from it. The water is supplied in such amount as to reduce the unit strength of the ultimate cured piling, but sufficiently strong and reliably consistent in its physical properties.
