Abstract
An apparatus for raising and supporting the foundation or slab of a building in which a lifting assembly is inserted underneath the foundation or slab and is adapted to receive a pipe assembly. A clamping assembly is provided for engaging a portion of the pipe assembly extending above the lifting assembly, and a hydraulic system extends between the lifting assembly and the clamping assembly for sequentially lowering the pipe assembly into the ground so that, when it encounters resistance, the foundation or slab is supported and can be raised to a predetermined level.
