Abstract:
A method for lifting and supporting above ground a concrete slab foundation employing hydraulic jacks includes installing piers in the ground, each with a pier extension protruding above ground. A lifting assembly is placed over each pier extension, the lifting assembly having a lift sleeve and upward extending lifting members. Then the slab foundation is poured, bonding a portion of the lifting assembly in concrete. After the slab foundation hardens, a jack is positioned on top of the pier extension, and lifting arms of the jack engage the lifting members. The jack is actuated to exert an upward force on the lifting assembly to lift the slab foundation above the ground. Then, the lift sleeve is rigidly secured to the pier extension, allowing the jack and lifting arms to be removed.

Claim (Index 17):
A method for lifting and supporting above ground a concrete slab foundation, comprising:\n installing a pier in the ground with a solid shaft protruding above the ground, the solid shaft being rectangular in cross-section; sliding a reinforcing sleeve over the solid shaft prior to installing the lifting assembly, the solid shaft and the reinforcing sleeve defining a pier extension, the reinforcing sleeve having a cylindrical inner wall; placing a lifting assembly over the reinforcing sleeve, the lifting assembly having a lift sleeve and a plurality of upward extending lifting members, the lift sleeve sliding over the reinforcing sleeve; pouring the slab foundation, bonding a portion of the lifting assembly in concrete; positioning a jack on an upper end of the pier extension, and engaging lifting arms of the jack with the lifting members; actuating the jack to exert an upward force on the lifting assembly, sliding the lift sleeve upward on the reinforcing sleeve until the lifting assembly and the slab foundation are in an upper position; rigidly securing the lift sleeve to the pier extension and removing the jack and the lifting arms; and dispersing grout between the cylindrical inner wall of the reinforcing sleeve and the exterior of the solid shaft after the slab foundation is in the upper position.
