ABSTRACT:
An improved foundation repairing system includes a plurality of pierheads secured to exposed portions of a foundation. Each of the pierheads has an angular ledge abutting an outer surface and a bottom surface of the foundation. A pier is driven, section by section, vertically downwardly through a pier guide of a respective one of the pierheads by a pier driver in conjunction with a pier driving bracket in order to obtain the necessary support from the underlying ground. The pier driver has a pair of opposing first upright members straddling the pier guide, which are temporarily attached to the foundation and a pair of opposing first foot members operably extending beneath the foundation. A plurality of secondary lifting mechanisms, in cooperation with piers previously installed by the pier driver, are adapted to cooperatively elevate the foundation. The pier guides of the pierheads are fixedly connected to the respective piers to provide permanent support for the foundation. A hardenable slurry provides further permanent support for the pierheads. A method for establishing permanent support for a building structure foundation is also provided.
