How do screw piles actually improve

[Jonh Newman]

Hello! I'm concerned about foundation stability on our building site. How do screw piles actually improve soil stability compared to other foundation types?

Hello! Screw piles provide exceptional soil stability through their unique design and installation method. Due to the special shape and characteristics of the screw fastening, the bearing properties of the soil are significantly increased, enhancing the overall stability of the structure. When the pile is screwed into the ground, the helical blades compact the surrounding soil rather than displacing it, creating a compression zone that increases load-bearing capacity. This is fundamentally different from driven piles that can loosen soil or concrete foundations that simply rest on the surface. The screw design creates mechanical interlocking with the soil, distributing loads across multiple depths rather than concentrating them at a single point. This distribution is particularly advantageous in variable soil conditions where different layers have different bearing capacities. The installation process - carefully screwing the pile directly into the ground - ensures reliable adhesion between the pile and soil at multiple levels. The result is high soil stability that can withstand various external impacts and loads, including lateral forces from wind or seismic activity.

This enhanced stability is one reason screw piles are increasingly chosen for residential and commercial construction where foundation performance is critical.
