Helical Pilings for Walkway & Boardwalk Foundations

The principles underlying the Chance Instant Foundation System utilizing helical pilings and helical anchors has been in use for more than 150 years. The system has proven very economical and effective in sensitive soils and difficult terrain or where a high water table prevents access or pouring of footings. Installation of the helical pilings is fast, can be built upon immediately and also provides uplift resistance to structures influenced by high tides or flood waters.

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

Benefits of Helical Pilings for Walkway & Boardwalk Foundation Anchors:


  • No soil excavation

  • Minimal impact on surrounding vegetation

  • Installation in limited-access areas

  • Transfers loads to competent bearing strata below weak soils and mud line
