Commercial Push Pier Systems in Nashville

Requirements vary by project and local jurisdiction. Commercial push pier projects typically involve engineered design or review to establish loads, pier locations, capacities and installation criteria. Permits and inspections can also be required. The Foundation Specialists can help sort out the engineering, documentation and permitting requirements that apply to your project.

Commercial push pier costs vary based on the number and type of piers, required capacities, installation depths, foundation configuration, access and excavation requirements. Mobilization, site constraints, engineering, permitting and restoration can also factor into total project cost. The Foundation Specialists can assess the structure and project requirements to develop a scope and estimate for the recommended system. 

Push piers are built as a permanent foundation stabilization solution. Steel components are engineered for long-term structural support, but service life may vary depending on the system, the site conditions, corrosion potential and installation. Project-specific specifications should address any additional corrosion protection or durability requirements for the site.

It will depend on the pier locations, access, excavation requirements and the facility itself. Push piers can usually be installed with relatively compact equipment and localized excavation, which can help reduce disruption compared with more extensive foundation work. The Foundation Specialists can review access and sequencing requirements when planning the project. 

There is no set depth for a push pier. Pier sections are advanced until the required installation resistance is reached, which may occur in competent soil or at bedrock. Actual depths can differ across a single site as subsurface conditions change, so push piers don’t necessarily have to reach bedrock to provide adequate support. 

The right system depends on structural loads, foundation configuration, subsurface conditions and whether you’re dealing with an existing or new structure. Push piers are often suited to heavier existing structures because installation uses the building as the reaction force. Helical piers don’t need structural weight for installation, which makes them useful for lighter structures, additions and new construction.

Push piers stabilize a commercial foundation by carrying the building’s load from unstable soils down to competent load-bearing soil or bedrock. Steel pier sections are hydraulically driven to the required resistance and connected to the existing foundation with steel brackets, creating a permanent deep foundation support system.
