Abstract
A piering system includes a heave plate attached to a foundation and supported by a pier. A downward facing socket is permanently attached to the heave plate. The socket receives the top end of a heavy stud of a coupling assembly, the bottom end of the stud is screwed into a captive nut of a shim-block. A nut is welded to the stud leaving about ½ inch of the stud protruding upwards for insertion into the socket. The nut may be turned to adjust the height of the stud. The shim-block and coupling assembly are supported by a head plate which is supported by the pier. The head plate includes a wide table for supporting a pair of jacks on opposite sides of a house jack facilitating installation of the system. The cooperation of the ball and socket helps to prevent “off-set loads” which otherwise may break the piering system.
