What Is a Commercial Push Pier System?
Commercial push piers are steel foundation supports hydraulically advanced through unstable soil to reach competent load-bearing soil or bedrock. The piers connect to the foundation using engineered brackets designed to transfer structural loads.
Each pier is effectively load-tested as it is installed to verify capacity. After all piers have reached the required resistance, the system is secured to provide permanent foundation support. Where commercial foundation settlement has caused a loss of elevation, a controlled lift may also be attempted when conditions permit.

How Push Piers Stabilize and Lift a Commercial Foundation
The weight of the structure provides the reaction force used to hydraulically drive steel pier sections through unstable soil. Pier sections are added until required resistance is achieved, so installation depth is set by site conditions rather than a predetermined depth.
Each pier is effectively load-tested as it is installed to verify capacity. After the piers are set, the building’s load shifts to competent strata, providing permanent stabilization. Where commercial foundation settlement has resulted in a loss of elevation, the system can also be used to recover elevation when conditions permit.

Legacy Supportworks Commercial Push Pier Solutions
Versatile Foundation Support for Commercial Buildings
Model 288 Push Pier System
The Model 288 Push Pier System provides deep foundation support for a wide range of established commercial structures. Its sleeved pier design helps increase resistance to bending near the foundation, which makes it a versatile choice when project loads and foundation conditions fall within the system’s design requirements.

Greater Capacity for Heavier Structural Loads
Model 350 Push Pier System
On commercial projects with greater structural demands, the Model 350 Push Pier System offers a larger-diameter foundation support option. The system expands the range of loads that can be addressed with push piers while retaining the installation advantages of a hydraulically driven deep foundation system.

High-Capacity Support for Demanding Commercial Projects
Model 400 Push Pier System
The Model 400 Push Pier System is built for demanding commercial foundation applications that require higher load capacities. Its larger steel pier sections and heavy-duty foundation connection deliver a high-capacity option on projects where structural loads surpass what smaller push pier systems can handle.

Push Piers vs. Helical Piers: Choosing the Right Deep Foundation Solution
Push piers use the weight of an existing structure as resistance during installation, which makes them well suited for many heavier existing buildings experiencing foundation settlement. They’re hydraulically driven until required resistance is achieved.
Helical piers are turned into the ground using rotational torque and don’t depend on structural weight for installation. This makes them a good fit for lighter structures, additions and new construction. Which system is appropriate ultimately comes down to structural loads, foundation configuration, subsurface conditions and project requirements.
