What are Helical Piers?

When your foundation is built on soil with low load-bearing capacity, the soil can give way under the weight of your house, causing settlement and foundation damage. Helical piers stabilize settling foundations by connecting footings and walls to more stable load-bearing soils deep below your home’s foundation. 

As the name suggests, helical piers are piers made of steel piers with a set of screw-like helical blades on the lower section. These helical blades help to advance the pier deep into the soil during installation and anchor it in place when load-bearing soil is reached. In many instances, helical piers will also lift and level your home by the time the installation is completed.

How do Helical Pier Systems Work?

When the soil below a home is unable to support the weight of the structure, the home will settle. This often leads to cracked, uneven foundations—in the worst cases, it can lead to extreme structural damage throughout the house. 

Many things can cause soil to weaken and become unable to support a home’s weight, such as poorly-compacted fill soil, moisture changes, and soil washout. Luckily, the undisturbed soil deep below your foundation is more compact and able to support heavier loads. 

Helical piers are driven to this deep, stable soil below your foundation. This creates a solid support base that transfers the weight of your home to stronger, more stable soil and bedrock. This makes helical piers the ideal fix for scenarios where surface soil has proven incapable of supporting your home’s weight. 

The Helical Pier Installation Process:

Helical piers can be installed from either the exterior or interior of your home, providing an opportunity to lift your home back to its original position by the end of the installation time. 

  1. Remove Soil: First, we remove the soil from the area where each helical pier is going to be installed. 
  2. Drive Piers: We start by advancing each helical pier section into the soil. This is done by mechanically screwing the piers. The first section of the pier has one or more helical blades welded to the shaft. Additional sections do not have bearing plates, and are instead used to extend the pier to the necessary installation depth.
  3. Install Steel Brackets: Once proper depths and capacities are achieved, we position heavy-duty steel foundation brackets below and against your foundation footing.
  4. Transfer Weight: After we install the steel brackets, the weight of your home can be transferred through the helical piers to stronger soil. 
  5. Lift Home: Once the weight of the home is transferred, we can attempt to lift your home back to its original position by making adjustments to the piers. 
  6. Replace Soil: After the entire process is complete, we carefully replace the soil around your home’s foundation.

Knowledge of the local soil conditions is often the first step in determining whether helical piers will be an effective solution for foundation repair.
