An apparatus and method for raising and supporting the foundation or slab of a building, in which a lifting assembly engages the lower surface of the foundation or slab and is secured thereto. A piling is disposed adjacent the lifting assembly and is engaged by a driving assembly. A hydraulic ram is connected between the driving assembly and the lifting assembly in the expanded position of the ram so that when said ram is retracted, the piling is driven into the ground until it encounters a predetermined resistance. The ram is further actuated after the predetermined resistance is encountered to raise said foundation or slab a predetermined distance.
