Helical Piles & Their Uses
Helical Piles are used to support structural foundations. Piles are driven to a depth where the ground is bearing, giving support to the structure.

What are Helical Piles?
Helical piles are a system of shafts and helix-shaped bearing plates. The number of plates needed and the depth needed to secure the pile to the Earth depend on the composition of the soil under and around the structure.
The terms helical piles, screw piles, helical anchors, helix piers, and helix anchors are often used interchangeably. The diameter of the helical plates needed is governed by the pre-determined loading and soil condition.
Why use helical piles?
Most foundation problems occur due to change in the soil structure around your building or home. The soil conditions underneath your building or home may shift or settle depending on terrain and/or water runoff around your building.
- to correct and level an existing foundation
- to support sagging, bending, bowing or buckling foundation walls
- to set a solid base on which to build a new foundation or deck platform
- for swimming pool stabilization
- as anchors for large tents or vertical poles
How are helical piles installed?
Helical piles are screwed into the ground. By keeping the helical plates at the same angles along the shaft, minimal soil disturbance occurs. Helical piles can be installed using small equipment in small spaces. The rotary action of installing helical piles does not produce ground vibrations. There is very little soil brought to the surface, therefore there are no extra dirt removal costs.
