Innovative Foundations for Boardwalks and Viewing Platforms

Summary

New and innovative alternatives to traditional substructures are available when determining the foundation design for boardwalks or viewing platforms. These alternatives can help minimize ground disturbance, be more cost effective, and provide greater life expectancy in wet and sensitive environments.

Helical piles and prefabricated concrete foundations are two innovative methods used for constructing elevated boardwalk
and viewing platform foundations across areas with standing water. The U.S. Department of Agriculture, Forest Service,
Trails Unlimited enterprise team used these methods on three projects. This tech tip provides step-by-step descriptions of
these installations and explains some advantages and disadvantages of using helical piles or prefabricated concrete foundations.

Keywords: boardwalks, elevated boardwalks, foundations, helical piles, prefabricated concrete foundations, standing
