Abstract
Apparatus and a method is disclosed for stabilizing the foundation of an existing building structure which may or has experienced settlement or movement. A support for the foundation is provided that is adapted to be located at a position in underlying relationship to the foundation structure. A screw anchor having an anchor shaft and at least one helix thereon is driven into the ground adjacent the foundation support. An inverted U-shaped coupler adapted to be temporarily secured to the foundation support receives a jacking device therewithin extending between the top of the coupler and the foundation support so that upon positioning of the support in supporting relationship to the foundation and insertion of the anchor into the ground, the support may be connected to the anchor shaft, the jacking device positioned between the support and the coupler so that added force may be applied to the support and thereby the foundation while the support and foundation are carried by the screw anchor, the support then affixed to the screw anchor, and the jacking device thereafter removed from its position between the base member and the coupler.
