Abstract: A method and apparatus for raising and supporting a foundation where a hole is excavated beneath the foundation, one or more pipes are driven into the earth at diverging angles to form a piling, and a jack is placed in the hole above the piling and beneath the foundation. A self-hardening fluid is forced into the jack to raise the foundation. A jack is created from a pair of hollow cylinders, each having a single closed end, and slidably engaged open end to open end for vertical movement when a self-hardening fluid is forced through an opening formed in one of the cylinders. The jack may be formed of an open-top cylinder having a concrete piston formed inside that is raised by pumping grout through an opening in the cylinder and into a void under the piston.
