A rotary drive machine for the installation of helical pile sections through installation openings in a slab floor inside of a building perimeter. A vertical frame having an upper end and an open lower end is positioned over an installation opening through which it is desired to rotationally install a helical pile section, and the vertical frame anchored to the slab floor. A rotary power means, attached to the helical pile section moves along a vertical movement guide and is driven by a vertical actuator to rotationally and vertically drive the helical section into the ground. A method of use is also disclosed.

A method for forming a foundation wall of a building structure having a building frame seated on the foundation, the method including coupling each of a plurality of elongated vertical members to a floor of the foundation and the building frame so that each of the vertical members extend between the floor and the building frame adjacent to an existing foundation wall, providing at least one elongated horizontal member through apertures of the vertical members such that the horizontal member extends between and passes through respective ones of the vertical members, coupling panels to the horizontal member so as to form, with the vertical members and the horizontal member an integrated self-supporting formwork which, with the existing foundation wall forms a cavity, having disposed therein, the vertical members and the horizontal member, and flowing concrete into the cavity so as to fill the cavity around the vertical members and horizontal member disposed within the cavity.

A foundation pier bracket system provides attachment of a pier shaft with a building or structure foundation such that the system provides securement to competent strata or soil below. The system can include a reinforcing sleeve and a bracket assembly. The bracket assembly can include a shaft receiving portion and a seat portion. The shaft receiving portion can define an aperture that is sized and shaped to receive a portion of the reinforcing sleeve therein. The seat portion can include a plurality of protruding members that protrude upwardly therefrom. The plurality of protruding members can be arranged such that they restrain lateral movement of a beam along the seat portion in at least one axis. The reinforcing sleeve can include a locking wedge that secures the reinforcing sleeve to the bracket assembly. A method of supporting a foundation of a building is also provided.

A foundation system for supporting a manufactured building from a ground surface, includes a pan to engage the ground surface and at least one bracket. The pan and brackets provide first, second, and third orientations. The first orientation includes one bracket mounted in a central area and oriented to receive two longitudinal struts couplable to a first beam and one lateral strut couplable to a second beam. The second orientation includes the central area being clear to receive a block pier and one bracket mounted longitudinally offset from the central area and oriented to receive one longitudinal strut couplable to the first beam and one lateral strut couplable to the second beam. The third orientation includes the central area for the block pier and two brackets mounted longitudinally on opposite sides of the central area and oriented to each receive one of two longitudinal struts couplable to the first beam.

A foundation support system for supporting a manufactured building from a ground surface, includes a pan configured to engage the ground surface. The pan includes a longitudinal bracket integrally formed in the pan. The bracket includes a pair of spaced walls extending in a longitudinal direction. First and second longitudinal struts include first and second lower strut ends, respectively, received between and attached to the spaced walls of the longitudinal bracket. The pan may also include an integrally formed lateral bracket which receives a lateral strut. The pan may include integral reinforcing ribs extending parallel to and between the walls of each bracket.

Described are an apparatus and method for driving piles prior to lifting and stabilizing foundations that have subsided in unstable ground. A press head, comprising two non-slip arms actuated by a safety lever, is connected to an angle cleat-type foundation piece secured to the foundation by a pair of hydraulic rams in order to drive the piles into the ground as far as the bedrock when the rams contract. The apparatus includes a safety system actuated by the lever for controlling the arms. In order to level the building, other hydraulic rams are installed on each driven pile, all connected in series in order that they may be actuated simultaneously in order to lift the building. When the foundations have been adequately raised and levelled, each pile and the corresponding angle cleat-type foundation piece, both made of steel, are welded in order to stabilize the foundations.
