How Helical Pile Blade Geometry Impacts Load-Bearing Capacity

Atlas Piling19 Feb, 2026Business

One of the most influential aspects of a helical pile driver is the diameter of the blades. Larger blade diameters generally increase the surface area in contact with soil, enhancing lateral friction and overall stability. This expansion of contact area distributes the applied load more evenly along the length of the pile, reducing stress concentrations that could lead to structural failure.
