Foundation Push Pier Solution

Foundation push piers repair and stabilize sinking or settling foundations.

Symptoms include things like a tilting chimney, jammed windows or doors and a sinking, cracking, buckling or uneven floor, especially in the basement, caused by unstable soil under the foundation or a foundation that wasn’t set correctly.

Push pier systems are usually installed on the outside, where soil is excavated to access the foundation footing, but can be installed inside where a small area of the basement floor will be cut out. They are first anchored with pier brackets that extend under the entire foundation wall, shifting weight onto the push pier and leveraging its push into the ground.

Push pier sections, or extensions, are made of corrosion-resistant galvanized steel that fit together to reach depths where they can find firm footing in load-bearing soil or bedrock. Thrasher's patented Push Pier System includes an external metal sleeve that extends from the bottom of the bracket, reinforcing this critical point and preventing common issues seen in installations that can cause push pier systems to buckle and rotate. 

Once installed, the push pier system can lift and stabilize the attached foundation to alleviate it from sinking.

Frequently Asked Questions

  • Push piers work by anchoring foundation walls on brackets and then hydraulically thrusting sections of hollow pipe past unstable soil into competent, load-bearing soil. The weight of the structure pushes against the pipes to help drive them downwards while lifting the foundation upwards. Once it reaches stable soil, where a foundation can sit reliably, push piers can be stabilized to support the foundation or raised to bring the foundation to a secure level. 

  • Foundation push piers can be used both inside and outside foundation walls. With exterior installation, soil excavation outside is required around the footing of your home to give the bracket enough space to support the entire foundation wall. With an interior installation, a small area of concrete must be removed for push piers to be attached to the foundation and driven down to a firmer footing. With either installation option, the area excavated or cut out is restored to its original state. 

  • Foundation push piers are primarily made from heavy-duty, corrosion-resistant galvanized steel. They also attach to the foundation with a steel-based bracket. Push piers are designed to permanently withstand the immense pressures from supporting an entire foundation. 

  • Once installed and the foundation restored, the push pier system requires very little maintenance or upkeep. If your foundation shows any further signs of unevenness, it’s possible you might need support from additional push piers.

  • The type of foundation that works best for push piers would be a heavier building with some distance beneath the ground to reach load-bearing soil or bedrock, requiring extensions to reach deeper depths. This makes them especially popular for larger projects or in areas with more unstable soil. Lighter houses closer to firmer soil underneath might be better suited for other options, such as helical piers. 

  • Push piers are typically installed underground, so they're not visible after installation completes. This applies to piers installed both inside and outside. The excavated soil or removed concrete are replaced, with very little to no sign of disruption.

  • Push piers are also referred to as resistance piers, jacked piles, or hydraulically driven piers.
