Abstract: A foundation lifting and support system and method according to which two mounting units are attached underneath the foundation and to a wall of the foundation, respectively. A piling is inserted thougb support sleeves of the mounting units and, and a load is applied by a hydraulic unit to the pilings to drive the pilings to bedrock. After resistance is encountered, an additional load is applied to raise the foundation and the foundation is secured in the raised position. The additional load can be applied by the same unit that applied the driving load or by a different unit.

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.
