Commercial Foundation Repair in St. Louis, MO
Foundation settlement can create serious problems for a commercial building, from cracking masonry and uneven floors to doors that no longer operate correctly. Our team at Perma Jack of St. Louis evaluates commercial foundation problems to determine where movement is occurring, what may be causing it, and the best way to stabilize the structure.
We have worked with foundation settlement since 1974 and have used hydraulically driven steel push piers on both residential and commercial structures. For commercial properties throughout the St. Louis area, our goal is to develop a repair plan based on the building, site conditions, structural needs, and access available for the project.
Signs of Commercial Foundation Settlement
Settlement does not always affect an entire building evenly. One portion of the foundation may move while another remains stable, creating differential settlement that places stress on walls, floors, openings, and other parts of the structure.
Signs that may justify a professional foundation evaluation include:
- Stair-step cracks through brick or masonry
- Cracks around doors and windows
- Uneven or sloping floors
- Doors that become difficult to open or close
- Separation between walls, floors, ceilings, or adjoining building components
- Foundation cracks that continue to widen or change
- Visible movement along exterior walls
- Portions of the building that appear lower than surrounding areas
Not every crack or uneven concrete surface means the structural foundation needs piers. Our team looks at the overall pattern of movement before recommending a repair.
What Causes Commercial Foundations to Settle?
Commercial foundation settlement usually occurs when the soil supporting part of the structure can no longer provide consistent support. The exact cause can vary significantly from one property to another.
Conditions that may contribute to settlement include poorly compacted fill, changes in soil moisture, drainage problems, erosion, underground utility leaks, and differences in the soils beneath separate parts of the building. Additions and changes to the structure may also need to be considered when evaluating how loads are being transferred to the foundation.
Subsurface conditions also vary throughout the Greater St. Louis area. Rather than assuming every property has the same soil problem, we evaluate the conditions affecting the specific building before recommending stabilization

How We Evaluate a Commercial Foundation
A good commercial foundation repair starts with diagnosis. Installing piers without understanding the settlement pattern can overlook the actual cause of the problem or lead to unnecessary work.
Our team evaluates the visible signs of movement along with the foundation, surrounding site conditions, drainage, access, and other factors that may affect the structure. We then determine where additional support may be needed and which repair approach makes sense for the property.
Commercial projects can also involve considerations that are less common on residential work, including building access, occupied spaces, utilities, equipment, tenants, project sequencing, and coordination with other professionals.
Commercial Foundation Repair and Underpinning Options
When the foundation can no longer rely on the soils directly beneath it, underpinning can transfer the structural load to stronger material deeper below the building.
Steel Push Piers
Our Perma Jack System® uses hydraulically driven steel push piers to transfer foundation loads through unstable upper soils to suitable load-bearing material below. We have used this type of system for foundation settlement since 1974, including commercial applications.
Push piers can be an effective option for stabilizing an existing structure because the building itself provides resistance as the pier sections are hydraulically advanced into the ground.
Helical Piers
Helical piers may be appropriate for certain commercial foundation conditions, particularly when structural loads, access, installation requirements, or site conditions make them a better fit.
Our team does not assume that every building needs the same system. The foundation type, settlement pattern, structural load, soil conditions, and available access all affect which repair method should be considered.
Planning Repairs Around Your Commercial Property
Commercial foundation repair is about more than installing structural supports. The work also has to fit the needs of the property. Depending on the project, pier locations may be accessible from the exterior, interior, or a combination of both. Equipment access, utilities, finished areas, employees, tenants, and normal building operations may all affect how the work is planned.
Our team considers these conditions when developing the project scope. When possible, thoughtful sequencing can help limit unnecessary disruption while still allowing the repair to be completed correctly.
Commercial Foundation Experience Since 1974
Our team at Perma Jack has been working with foundation settlement since 1974. Over that time, the basic objective has remained the same: identify why a structure is moving and provide dependable support where the existing foundation can no longer rely on the soils beneath it.
For commercial properties, that requires looking beyond the visible crack. We consider the building, settlement pattern, structural support, access, site conditions, and repair requirements before determining how the foundation should be stabilized.
Request a Commercial Foundation Evaluation in St. Louis
If you are seeing cracks, uneven floors, wall movement, or other signs of settlement in a commercial building, the first step is determining what is actually happening beneath the structure. Our team at Perma Jack of St. Louis can evaluate the property, identify areas of concern, and explain the foundation stabilization options that may fit the building.

Commercial Foundation Repair FAQs
Do cracks in a commercial building always mean the foundation is settling?
No. Cracks can develop for several reasons, and not every crack requires structural foundation repair. The location, direction, size, progression, and surrounding signs of movement all help determine whether settlement may be involved.
Are push piers or helical piers better for commercial buildings?
Neither system is automatically better for every commercial property. The appropriate system depends on the structure, loads, soil conditions, access, settlement pattern, and repair objectives.
Can foundation repair be completed while a commercial building is occupied?
In some cases, yes. The answer depends on where repairs are required, how the building is used, equipment access, safety requirements, and the amount of excavation or interior work involved. These conditions should be considered when the project is planned.
Does commercial foundation repair require an engineer?
Some projects may require engineering based on the structural conditions, repair scope, or local requirements. Engineering needs should be determined as part of the project evaluation rather than assumed for every building.
How long does commercial foundation repair take?
Project length depends on the number of repair locations, accessibility, foundation type, building conditions, permitting requirements, and other site-specific factors. We evaluate those conditions before developing the repair scope and schedule.
Are There Engineering and Permit Requirements for Commercial Work?
Some commercial foundation projects may require structural engineering, permits, plans, or inspections depending on the type of repair and the municipality where the building is located. Requirements can also vary based on the size and complexity of the project.
