Abstract

The present invention is a foundation piling system in which pilings are used which support a foundation system in soil having a varied composition and moisture content which eliminates the need for drilling a hole in the ground to receive pilings formed of steel pipes. The pilings extend into concrete grade beams forming a portion of a monolithic system including a concrete slab.
