Abstract
An apparatus for lifting and stabilizing sunken or settled foundations, slabs, footings, etc. includes a lifting plate having a pipe section solidly secured thereto, for passing concentrically over the anchor pier used in such operations. The concentric lifting plate pipe precludes cocking or tilting of the plate relative to the anchor pier and foundation structure, thereby greatly improving the security of the lifting operation. As a result of the increased lifting plate stability provided by the present invention, only a single clamp is needed for securing the lifting assembly to the foundation. The clamp is adjustably positionable as required, to secure to a solid area of the foundation structure. The present system secures the plate to the pier using mechanical fasteners, thus precluding requirement for costly welding and other metal forming equipment. A method of raising or stabilizing a foundation or similar structure using the present apparatus, is also disclosed.
