ABSTRACT:
A method and apparatus for supporting various structures, and especially freestanding structures such as walkways, boardwalks, prefabricated buildings, electrical towers, and decks. The apparatus includes a pier assembly comprising a pier member connected to a helix, the pier member also having a compression member fixed to an intermediate portion thereof. The compression member having an upper end, a lower end, and an outer surface of a generally frusto-conical configuration. Upon rotation of the pier assembly, the compression member is forced downwardly into the earth thereby compressing and compacting the earth there beneath to provide a stable support structure. Furthermore, a tubular member may be inserted at the upper end of the compression member and a body of rigid material may be provided within both the compression member and the tubular member.
