WebFeb 28, 2024 · 3. Helical piles are most useful and work well in low or shallow boardwalk conditions, and even top-down construction applications, but not elevated boardwalks. As mentioned above in the crucial point #2, the helical piles are drilled, not driven, to a specific depth calculated for required boardwalk load capacity. Web1. Axial Loads. An axial load may be either compressive (downward) or tensile (uplift). When it is compressive, deep foundations resist the load using friction resistance and toe bearing resistance, as shown in Fig. 1. However, when the load is tensile, the resistance is caused by side friction and the weight of the foundation as shown in Fig ...
