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.
