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.
