Helical piles provide solutions for walkway and boardwalk foundations where installation of conventional footings may be prohibitive because of a high water table or because the earth is submerged at the footing locations. Installation of the helical piles is fast, can be built upon immediately and also provides uplift resistance to structures influenced by high tides or flood waters.

Helical piles prevent the walkway or boardwalk from undulation, can be rebuilt upon after the timber elements have become worn and can be made to withstand the effects of corrosion through galvanization and sacrificial anodes.
