ABSTRACT:
An apparatus for stabilizing the foundation of a building structure includes a support assembly fastened to the foundation and a screw anchor installed in the earth in generally upright disposition with an upper end thereof located adjacent the foundation. The upper end is secured within a sleeve of the support assembly by a bonding composition to prevent movement of the screw anchor relative to the sleeve. During assembly of the apparatus, a lower bracket of the support assembly is attached to the foundation of a building to be stabilized, and the screw anchor is installed in the earth in generally upright disposition with an upper end of a rod of the anchor located adjacent the lower bracket. The sleeve is placed over the upper end of the rod, and a bonding composition is inserted into the interior space of the sleeve between the sleeve and the rod. The sleeve is also attached to the bracket to prevent settling and uplift movement of the foundation relative to the screw anchor.
