Building foundation repair pier and permanent support

WALLIMAN GREG G

Methods and apparatus are provided for a system for raising and permanently supporting a sunken building foundation footing. The system includes a cylindrical sleeve disposed inside a hole cored through the footing from a top surface of the footing adjacent a stem wall to a bottom surface of the footing, wherein the sleeve has an inner diameter large enough for pier extensions to pass through. A bracket positioned on the top surface of the footing over the sleeve has a center hole with a diameter equal to or greater than the inner diameter of the sleeve. The system may further include a mechanical connection from the bracket to the footing configured to carry a foundation lifting force from a hydraulic ram.
