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.

Abstract: An improved method and apparatus for supporting and shoring building foundations and walls in which one or more pilings are disposed at a point outside the perimeter of a structure. The pilings are driven into the supporting strata to a point determined by said strata's resistance to a predetermined amount of driving force. The pilings thus disposed provide a foundation for the subsequent attachment and securing of the apparatus of the present invention which functions to raise and support the foundation or wall to a predetermined level. The apparatus of the present invention includes a lifting arm for engaging the foundation, a sleeve portion for guiding the pilings, a removably secured lifting saddle, and a hydraulically operated jack for applying a force between the saddle and the pilings to raise the foundation a predetermined distance.
