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.
