<p>An apparatus (10) and a method (30, 40) are provided for lifting and leveling an existing building (100). At least a first non-cylindrical support section (12) having a substantially rectangular shape and first and second ends is located within the earth (7) at a position underneath the existing building (100). A cap support section (13) is placed in contact with the second end of the first non-cylindrical support section (12). A jack (73/74) is disposed on the upper side of the cap support section (13) and raised until the foundation (96) of the existing building (100) has been lifted to a desired height. The non-cylindrical support section (12) has low bearing and high friction characteristics. The low bearing characteristics enable the apparatus (10) to be driven further into the earth (7) than cylindrical pilings that are commonly used to lift and level existing buildings (100). The high friction characteristics assist in maintaining the stability of the apparatus (10) once installed.</p> |
