Abstract
Installation of support piers for a structure comprises the steps of positioning a hollow tube in a soil matrix followed by removal of soil from the hollow core, filling the core with an aggregate, subsequent raising and lowering of the hollow tube, compacting the aggregate by means of a mechanical device affixed to the bottom of the hollow tube to and also applying lateral forces to the aggregate against the walls of the cavity formed in the soil matrix, thereby pushing a portion of the aggregate laterally into the soil matrix.
