Abstract: A method and apparatus for rapidly constructing a structural pier comprising the steps of placing into a soil under a structure to be supported a casing having an inner diameter and an outer diameter, positioning an injection tube into the inner diameter of the casing, and injecting an expansive material into the casing. Optional perforations in the casing allow some of the expansive material to be ejected from the casing into the surrounding soil to create fingers or branches for the purpose of adding friction to the structural pier.

Abstract: A spider bracket includes a plurality of arms defining a planar surface and adapted to abut with the coiled section of a heater element and a crimp bracket extending from the arms. The crimp bracket has a plate extending substantially perpendicular to the planar surface and having a plurality of crimp members extending substantially perpendicular to the plate in opposite directions thereof. The crimp members have a substantially U-shaped configuration for receiving the ends of the element. The crimp members have a single crimp arm and a positioning arm whereby upon presenting the lower planar surface of the element to the arms and at to the ends of the crimp member, crimping the crimp arm about the end of the heater element, the planar surface of the arms is substantially coplanar with the lower surface of the element.
