What Is a Commercial Push Pier System?
Commercial push piers are steel foundation supports driven hydraulically through unstable soil to reach competent 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. Once every pier has reached the required resistance, the system is secured to deliver permanent foundation support. Where commercial foundation settlement has caused a loss of elevation, a controlled lift may also be attempted when conditions allow.
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. Sections are added until the required resistance is reached, so installation depth is determined by site conditions rather than a predetermined depth. Every pier is effectively load-tested during installation to verify capacity. Once the piers are set, the building’s load is transferred to competent strata, delivering permanent stabilization. Where commercial foundation settlement has led to a loss of elevation, the system may also be used to recover elevation when conditions allow.

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 improve resistance to bending near the foundation, making 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
For commercial projects with greater structural demands, the Model 350 Push Pier System provides a larger-diameter foundation support option. The system widens the range of loads push piers can address 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 offer 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 rely on an existing structure’s weight as resistance during installation, which makes them well suited for many heavier existing buildings experiencing foundation settlement. They are hydraulically driven until the required resistance is reached.
Helical piers are advanced into the ground with rotational torque and don’t rely on structural weight for installation. That makes them well suited for lighter structures, additions and new construction. Which system is appropriate ultimately comes down to structural loads, foundation configuration, subsurface conditions and project requirements.
