What Is a Commercial Push Pier System?
Commercial push piers are steel foundation supports hydraulically advanced through unstable soil to reach competent bearing soil or bedrock. The piers are attached to the foundation with engineered brackets designed to transfer structural loads.
Every pier is effectively load-tested during installation to verify capacity. Once all piers have reached the required resistance, the system is locked off to provide permanent foundation support. Where commercial foundation settlement has caused a loss of elevation, a controlled lift can also be attempted when conditions permit.

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

Versatile Foundation Support for Commercial Structures
Model 288 Push Pier System
The Model 288 Push Pier System delivers deep foundation support across a wide range of existing commercial structures. Its sleeved pier design adds resistance to bending near the foundation, making it a versatile choice when project loads and foundation conditions fall within the system’s design requirements.

Added Capacity for Heavier Structural Loads
Model 350 Push Pier System
On 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 keeping 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 provide a high-capacity option for projects where structural loads go beyond the capabilities of smaller push pier systems.

Push Piers vs. Helical Piers: Choosing the Right Deep Foundation Solution
Push piers rely on an existing structure’s weight as resistance during installation, making them a good fit 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 using rotational torque and don’t rely on structural weight for installation. This makes them well suited for lighter structures, additions and new construction. The right system ultimately depends on structural loads, foundation configuration, subsurface conditions and project requirements.
