Helical piles are a popular choice for walkways, boardwalks, porches, beach stairways, observation decks, docks, and pedestrian bridges. The driving force for the use of helicals in these applications is environmental sensitivity. Helical piles install gently with little disturbance to wetlands and other sensitive areas using small, low-impact equipment. There is no soil excavation required with minimal impact on vegetation or aquatic animals and helicals can be installed in remote, limited-access areas.
The Nature Conservancy and Appalachian Trail Commission, as well as local, state, and federal parks and recreation authorities each use helical piles to support elevated structures in pristine, sensitive environments.
Helical piles are extendable, galvanized steel pipe or solid square bar shafts with helical plates welded to the shaft. Plain extensions are added as they are screwed into the earth to reach competent load-bearing soil. Portable hand-held installation equipment has been used for the more remote project locations with equipment and piling segments transported by volunteers.
