ABSTRACT:
A method and apparatus for raising, leveling, and supporting a foundation by placing steel piers beneath the necessary peripheral and interior beams and using a jack to raise the slab beams, then allowing the slab beams to rest on piers. The piers are constructed from steel piling segments, driven into the ground, connected with adhesive, and anchored at a depth offering reactive force sufficient to support the foundation. The piling is pointed at its bottom facilitating insertion and preventing upheaval. A crown is attached to the upper most end of each pier which offers a platform to provide a stable support once the jack is removed and easy access to the slab beam for later readjustment. Multiple piers are utilized to achieve a level foundation. Piers may be placed beneath interior beams on a slab without drilling holes in the interior of the slab.
