Abstract

A system for raising and supporting the foundation or slab of a building, in which a mounting assembly is bolted to the foundation or slab and includes a pair of support sleeves which receive a piling and which are connected to the foundation or slab. A clamping assembly engages the piling, and a hydraulic ram is connected between the clamping assembly and the mounting assembly in the expanded position of the ram so that when the ram is retracted, the piling means is driven into the ground until it encounters a predetermined resistance. The ram is further actuated after the predetermined resistance is encountered to raise the mounting assembly and the foundation or slab a predetermined distance after which the mounting assembly and the foundation or slab are secured to the piling.
