At Thrasher, we recommend foundation push piers to stabilize foundations that are settling or sinking and showing symptoms such as cracked foundation walls, tilting chimneys, and jamming doors and windows. Our patented system provides effective and permanent repairs for damaged foundations, ensuring that you have a safe, stable home. This article will explain the process for installing push piers.

What are Push Piers?
Let's start at the beginning. Push piers are made with heavy-duty steel and are connected to your foundation by a steel foundation bracket. The piers are driven deep below your home in sections until the piers reach strong supporting soils. Steel brackets connect piers to the foundation, effectively transferring the weight of the structure to the deeper load-bearing soil.
How to Install Our Foundation Push Pier System
The Supportworks Push Pier System permanently stabilizes foundations that are damaged by settlement. Our warrantied solution can be installed on your foundation in four simple steps:
1) Prepare the Foundation Footing
For an outside installation, the soil around your foundation must be excavated so that the footing is exposed. For an inside installation, a section of your slab floor will need to be removed to expose the footing. The slab will be restored after the installation.
A section of the footing will be prepared for each foundation pier so that the pier is supporting the wall directly, and not simply lifting the section of the footing that extends beyond the walls. This makes for the strongest installation.
2) Secure the Foundation Bracket
A steel bracket is secured to the foundation footing at each pier location. With push piers, the foundation bracket is installed before the piers are driven into the earth. This allows the push pier to take advantage of your home's structure, stabilizing the pier as it is advanced deep below your foundation to competent soils.
3) Install the Steel Piers
The hollow steel piers are installed in sections, or extensions, that are connected to each other. One at a time, each extension is driven down through the bracket until strong supporting soils or bedrock are reached.
These steel piers are the strongest component of our foundation pier system and are responsible for transferring the weight of your structure to competent load-bearing soil. Our foundation piers are available with a galvanized steel design. These piers are corrosion-resistant, for long-lasting durability.
4) Stabilize and Restore the Foundation
Once all foundation piers have been installed, the settlement of your foundation will be permanently halted. At this time, we will determine if the foundation should remain at its stabilized location or be lifted back to its original position. Following this final stabilization, slabs are repaired and soil is replaced to totally hide the repair.
5) Why Thrasher Push Piers Are Top of the Line
The Supportworks push pier system is engineered to handle the heaviest structural loads. As the weight bears down on the foundation bracket, the bracket exerts great pressure on the pier directly beneath the bracket.
This is the most critical point of stress on a foundation push pier system, where extra strength in the pier helps the most. Our push pier system includes a steel sleeve that extends from the bottom of the bracket, reinforcing the pier at this critical point.
The external sleeve strengthens piers during installation as well, which prevents the kinking, buckling, and rotating that is commonly seen during the installation of other push pier systems.
Advantages to Using the Thrasher Push Pier System
- Year-round installation
- Can be installed inside or outside the foundation
- Push piers reach greater depth than any other option available
- Installation does not require use of heavy equipment
- Can lift foundation back to original position
- Repair not visible after installation is complete
- Designed with corrosion-resistant galvanized steel
- A rugged foundation bracket design
- An innovative steel sleeve design to avoid warping
A Word of Warning:
Beware of contractors who tout the strength and capacity of their system's bracket. The foundation bracket is only one piece of the puzzle!
Because push piers are installed adjacent to a foundation footing and not directly underneath, the weight instead bears directly down on the bracket, and the pressure is then transferred down to the pier itself. Engineers refer to this effect as eccentricity.
Because of this eccentricity, all pier systems see the greatest level of bending stress directly below the bottom of the foundation bracket. Installing a steel sleeve on the pier directly below the bracket is a cost-effective way to effectively strengthen your entire pier system.
