The short answer: At Jet Foundation Repair, we believe in transparent pricing. Our Fortress InvisiBeam® Carbon Fiber straps are installed starting at $900 per strap.

The detailed answer: The total cost depends on the length of the wall and the severity of the bow. Because carbon fiber straps must be spaced every 4 feet to meet code requirements, you can estimate your cost by measuring the affected area.

For a typical St. Louis basement with a bowing wall, here is what the math usually looks like:

• Minor Bowing (10-foot section): ~3 straps ($2,700)

• Average Wall (20-foot section): ~5–6 straps ($4,500 – $5,400)

• Severe Bowing: If the wall is bowed more than 2 inches, or requires steel I-beams, costs can range from $6,000 to $10,000+ depending on if excavation is needed.

Why this is the best value: While $900/strap is an investment, it is often 30-50% less expensive than the alternative of excavating the outside of your home to straighten the wall. Plus, unlike steel beams which cost a similar amount but ruin your basement's aesthetic, InvisiBeam adds value by allowing you to finish and paint your basement walls seamlessly.

The honest answer: Yes, if left ignored for many years, a bowing wall can eventually lose its structural integrity and collapse. However, foundation failure is typically a slow, progressive process—it rarely happens overnight without warning signs.

The reality (No scare tactics): At Jet Foundation Repair, we inspect thousands of St. Louis basements, and we believe in putting data before fear. In our experience, only about 1 out of every 100 homes we visit presents an imminent safety risk.

Most bowing walls are in a stage of slow movement. While they look concerning, they can usually be permanently stabilized with InvisiBeam or other methods long before they become dangerous.

When you should act: While immediate collapse is rare, the problem will get worse and more expensive to fix if you wait. If you are concerned for your safety—especially if you notice the wall moving quickly, hear loud popping sounds, or see gaps opening up rapidly—please contact us or another structural professional immediately. It is always better to verify your safety with an expert inspection than to worry.

The short answer: No. If your wall is bowing, curving, or has horizontal cracks, epoxy alone is not a solution.

The explanation: Epoxy injection is a fantastic waterproofing seal for vertical cracks that are stable (not moving). However, it has very little tensile strength.

Think of a bowing wall like a broken leg.

• Epoxy is like putting a band-aid on the skin. It might cover the crack, but it does nothing to support the bone.

• InvisiBeam Straps are like a cast or a splint. They provide the structural strength needed to hold the wall together and prevent it from bending further.

If you fill a horizontal structural crack with epoxy without installing reinforcement straps, the wall will continue to move. The crack will simply re-open (often right next to the epoxy line), and you will have wasted money on a repair that didn't fix the root cause.

Our recommendation: We always seal the crack to keep water out, but for bowing walls, we do it alongside the installation of carbon fiber straps to ensure the repair is permanent.

For most residential bowing walls (less than 2 inches of movement), Carbon Fiber is superior. It is stronger than steel, requires no maintenance, and preserves your living space.

Steel beams are typically reserved for extreme cases where the wall has moved significantly.

Yes! Lifetime, and transferable in case you sell the home. sale. Additionally, should a failure occur, Fortress will pay in full for materials and labor to an authorized InvisiBeam® installation contractor to repair or replace defective material. More information here.

Most carbon fiber installations are completed in one day, with no excavation required.
