The method of installing the mastic footprint may be used as a repair or in connection with a new installation of the structure. The method produces a mastic footprint that is resistant to infiltration of water, fuel, and salt, including mixtures thereof. The method further produces a mastic footprint that is thermally resistant. In repairs, the mastic footprint of the method provides longevity of use of at least one year and up to 5 years prior to any repair or replacement. In new installations, the mastic footprint provides longevity of use of at least 1 year and up to 15 years prior to any repair or replacement. Finally, the method of installing a mastic footprint does not affect the structural integrity of the adjacent or surrounding surface material, where the adjacent or surrounding surface material does not require repair or replacement sooner than if the method had not been deployed.

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 cutting tool adapter for creating an underpinning structure and method of creating the underpinning structure are provided. In some examples, the cutting tool adapter may connect a cutting tool to a working machine arm to enable the cutting tool to cut and dislodge soil below an existing foundation or structure. As the soil is cut and dislodged, it is mechanically mixed with an additive, such as a cementitious material, via the cutting tool. The mixed soil and additive may then harden in the area below the existing structure or foundation to create an underpinning structure to provide additional support for the existing structure or foundation.

A pier bracket comprises a seat including a base plate and an upper plate extending orthogonally from the base plate wherein, when the base plate is positioned for supporting a structure, the upper plate is adjacent to the structure for securing the upper plate to the structure. A tubular member is mounted to the seat and adapted to slidably receive structural piers. A planar support plate is distally spaced from and parallel to the base plate. Each of a pair of side plates extend between an opposite side edge of the base plate and the support plate.
