A method of modifying the structural integrity of material in a subterranean earth situs. The method comprises the steps of mechanically digging into the situs to break the material into pieces and, simultaneously, hydraulically admixing a modifying agent with the pieces by introducing the modifying agent into the pieces at a velocity in the range of from about 300 ft./sec. to about 2500 ft./sec. The method is particularly suitable for improving the strengh and load-bearing capacity of material in a subterranean earth situs. Also provided is a method of modifying the stuctural integrity of material in a subterranean earth situs and installing a pre-formed structural element therein.
