You’ve noticed cracks in your commercial building foundation walls.
- Horizontal Or Vertical Wall Cracks
- “Stair-Step” Or Diagonal Cracking
- Bulging, Buckling Foundation Walls
- Pushing In At The Bottom Of The Wall
- Sliding In At The Top Of The Wall
How to Fix It:
Foundation wall cracks have several different causes. Each wall crack repair has its own unique method. Concrete walls may experience small cracks as they cure. These are normal and may be no cause for alarm.
If your walls are cracking due to foundation settlement issues, foundation piers may be your solution. If your foundation walls are failing due to expansive soils, a wall anchor system may solve your problem.

Different Types of Commercial Foundation Wall Cracks
Foundation cracks vary in severity from a simple cosmetic issue to a major problem. However, even serious foundation problems, when addressed early on, can be quickly and permanently fixed.
Cracks form in foundation walls for three main reasons:
As concrete cures, it is common for small cracks to appear in foundation walls. These cracks are very common, and they’re not a sign of a major foundation problem.
Shrinkage cracks tend to be very small “hairline” cracks that are usually 1/16″ wide or less. They generally occur near the center of a span and maintain a consistent width for the length of the crack.
A Word Of Warning: Be careful not to assume that a crack in the foundation is merely a shrinkage crack! If you see cracks in the foundation walls of your building, monitor them regularly. If the cracks widen enough that you can fit a dime in them, or one end of the crack grows wider than the other, you should consult a foundation contractor right away.
When the soils underneath the foundation fail to support the weight of the building, the foundation will begin to settle unevenly, and cracks will appear. As vertical cracks form and the wall or corner of the house begins to rotate, you will typically see cracks that are wider at the top or bottom.
Foundation cracks that are caused by settlement are very serious, and they will only get worse over time as the building continues to move. If you are concerned that the foundation may be cracking due to settlement issues, it’s best to consult a professional right away.
If you have clay soils around your building, they can expand and contract significantly as they become wet. If left unrepaired, this kind of damage can worsen until the wall fails completely or is beyond repair. By addressing the problem of failing walls quickly, repairs can be completed in as little as a day.

Wet clay soils can expand enough to put literally thousands of pounds of pressure on a foundation wall. This can force the walls inwards, sometimes causing them to buckle and crack. Look also for walls pushing in at the bottom or tilting in at the top.
Repairing Commercial Foundation Wall Cracks
Whether the problem is expansive soils or unstable soils underneath your building’s foundation, there are effective solutions that can permanently repair your structure. At AquaGuard Foundation Solutions, we use the following methods to restore structural integrity to compromised foundations.
Foundation Pier Systems
Foundation piers are an excellent way to stabilize and potentially lift a foundation that is resting on soils that cannot support the weight of the building. Foundation piers are a permanent solution for buildings that are settling, and they can be installed year-round.
Push Piers stabilize foundations by transferring the weight of the building deep below the foundation, reaching to bedrock or competent strata.
Helical Piers are an excellent way to stabilize foundations when there is sufficient knowledge of local soil conditions. They are advanced into the soils underneath the foundation via a helical blade.
Wall anchor systems are ideal for stabilizing and potentially straightening foundation walls that are buckling due to pressure from expansive soils.
Wall Anchors use the soils beyond the foundation walls to exert counter pressure on failing foundation walls. This holds the walls in place on the short term, and it allows your contractor to attempt to straighten the walls back to their original position over time. This solution requires access to the soils beyond your foundation walls. If exterior access is limited or not possible, we recommend installing the PowerBrace™ Wall Repair System as an effective solution.
Temporary Fixes For Foundation Walls
Many contractors will try to earn your business by suggesting a cheap solution that they know will not permanently solve your problem. Solutions that hide your issues, such as painting over drywall cracks or tuckpointing cracks in brick are short-term solutions only. If the cause of the problem is not addressed, the cracks will soon reappear, and more covering up and patching will be needed.
Additionally, attempts to seal drywall or mortar cracks are easy to identify, due to variances in the finish or workmanship. When tuckpointing brick veneer, it’s especially difficult to match original mortar colors. And if you decide to properly repair your foundation later, these “patches” may need to be removed before the repair can properly restore your walls.
Can Settlement Issues Occur if the Foundation Walls Aren’t Cracked?
There are several foundation problems that can occur even when the foundation walls themselves are not cracking.
More about sinking crawl spaces.
Heaving Or Sinking Slab Floors
When the soils underneath slab floors settle or are washed away, the floor itself will begin to sag. Likewise, when the soils underneath a concrete floor expand, the slab will begin to lift upwards.
Either way, the movement of concrete floors can lead to cracks along drywall and the floor itself.
