ABSTRACT:
A tubular piling pipe having a plurality of cantilevered perforations formed in the exterior wall of the pipe defined by individual bendable necks and carrying enlarged-in-cross section tabs at their free extremities to provide foundational support. The bendable necks have elastic limits such that an outward force of sufficient magnitude will permanently force the necks and respective tabs radially outward and into the surrounding soil such that the tabs define anchor fingers.
