Abstract:
An apparatus and method for raising and supporting the foundation or slab of a building, in which a lifting arm assembly engages the lower surface of the foundation or slab and is secured thereto. A piling assembly is disposed in a support sleeve adjacent the lifting assembly and is engaged by a clamping assembly. A hydraulic ram is connected between the clamping assembly and the lifting arm assembly in the expanded position of the ram so that when the ram is retracted, the piling is driven into the ground until it encounters a predetermined resistance. A drive plate is placed in operative relation to the piling assembly and over a pair of rods attached to the lifting arm assembly. The ram is further actuated after the predetermined resistance is encountered to raise the lifting arm assembly, the rods, and the foundation or slab a predetermined distance relative to the drive plate, after which the rods are secured to the piling assembly.
