Basement walls are an important component of the foundation as they provide support and stability to the entire structure. If the basement’s integrity has been compromised, the walls might start bowing or bending inward. Bowed basement walls are signs of serious structural issues. It’s important to have them inspected and repaired promptly. 

Repairing bowing basement walls repair will cost you money depending on several factors. Let’s take a look at the average cost and different repair methods that you can choose from

Average Cost of Basement Wall Repairs

The typical cost to repair a bowing basement wall is between $75 to $400 per foot. Carbon fiber reinforcement costs $350 to $1,000 per strap, while wall anchors are around $400 and $700 each. If the structural issue is too severe, a complete wall replacement can cost upwards of $30,000. 

Keep in mind that this is only a rough estimate. There are many factors that come into play when calculating the repair cost. You can compare estimates from different contractors to see which one offers the best value.

Although the cost of repairing a bowing basement wall is high, we don’t recommend going down the DIY route. Attempting to fix the problem on your own can lead to more problems. Repairing any foundation-related issue is a much larger undertaking than most DIY jobs. It’s best to hire a professional with years of experience and specialized knowledge.

Common Repair Options for Bowing Basement Walls

Wall Anchors

If your wall is bowing more than two inches, wall plate anchors can be installed on the basement walls. A wall anchor consists of two steel plates attached on the inside and outside of your basement. These plates are connected by a steel shaft that takes the pressure off the wall. 

When the anchors are tightened properly, they can hold your wall in place and stop inward movement. Anchors are placed every 5 feet along the bowing wall, which means you’ll likely pay $80 to $140 per foot.

Carbon Fiber Straps 

This method involves installing long strips of metal on your bowing basement wall. Placing carbon fiber straps is a nondestructive option because it doesn’t require any excavation. In general, the straps only need to be placed vertically along the wall. The best practice is to install them every four feet and anchor them at the top and bottom. Once the installation is complete, you can even paint over the straps or seal them with epoxy for longevity. 

Helical Tiebacks

Another solution for reinforcing bowing basement walls is helical tiebacks. These long steel, screw-like shafts are drilled through the basement wall to support and straighten bowed basements. Helical tiebacks are twisted to create tension in the wall, which helps pull the wall back into its previous position.

Since helical tiebacks provide a long-term solution, they are the most expensive repair method. A single tieback costs $1,500 to $1,800 and should be installed every five feet.

Wall Straightening

If you’re looking for a more permanent solution, then wall straightening is the best choice for you. This technique involves excavating the ground outside and pushing the wall back into place. Heavy-duty hydraulic jacks and steel I-beams are used to prevent the walls from bowing any further. Once the wall is straightened, additional reinforcement straps and anchor plates can be installed to stabilize the basement walls. This repair method will not make your wall perfectly straight, but it can keep them in an upright state. 

In some cases, wall straightening is not the best option because it’s too invasive. The process requires more labor and materials. We recommend that you consult with a basement contractor to determine the best course of action.
