A helical pier is a steel shaft, usually square with helices, similar to a large screw that provides a foundation support for various types of structures. Helical piers are often used when challenging soil conditions prohibit a traditional foundation system. They are also commonly used to correct and support existing foundations that have settled or failed.
The purpose of a helical pier is to transfer the load of the structure through the unsuitable soil to a stronger, more suitable soil deeper in the earth. Helical piers are a deep foundation solution. Helical pier applications can be considered when plans call for caissons, driven piles, mini piles, etc.
If you own a home, you may need helical piers if you are experiencing cracks in your drywall, foundation, or your home’s exterior. These are all signs of a failing foundation that can be corrected by installing helical piers.
In the commercial arena, you may need helical piers if you are working on a new construction project where a soils report requires a deep foundation system, or over excavation to support typical building loads.
Industrial projects use helical piers because of their ability to be installed in limited spaces, with minimal disruption to the daily operations of the plant and affected equipment.
