Carbon Fiber Straps for Basement Wall Repair
Bowing foundation walls are most often caused by hydrostatic pressure—water-saturated soil pushing against the exterior of your basement walls.
Why Foundation Walls Bow
Bowing foundation walls are most often caused by hydrostatic pressure—water-saturated soil pushing against the exterior of your basement walls. Over time, this pressure can cause basement walls to bow, especially between structural corners.
Common causes include:
- Poor drainage or grading
- Expansive clay soil
- Freeze-thaw cycles
- Prolonged rain or groundwater buildup
Left untreated, bowing can worsen—leading to foundation cracks, water intrusion, and even wall failure.

From the project manager through all the folks working this huge mess, I am so thankful for the job that was completed. Kyle and team put up with all my questions and dealt with temporary fencing for my dogs. Always rrspectful and polite. I can't rate them or Anchored Walls high enough! Also Deb in the office keeping me updated and answering more questions. Lucas and Carson putting in the sump pump. If you have basement issues, definitely call this company!!

After getting bids and talking with a few different contractors regarding what we needed for waterproofing our basement, I was feeling pretty overwhelmed, anxious and stressed out. Elliott was a breath of fresh air. He's a very nice, respectful guy. He is very knowledgeable and was easy to talk to. After speaking with him, I felt more at ease and less anxious about the whole process. Because of Elliott, we plan to move forward with Anchored Walls for our basement waterproofing.

Carbon Fiber Straps for Basement Walls
Our team uses a proven carbon fiber strapping system, reinforced with a steel bracket anchoring method, to lock walls in place and prevent further movement.
Here’s how it works:
- 1. Wall Prep: We scarify the surface—removing paint and coatings—to ensure maximum bonding.
- 2. Epoxy Application: Each carbon fiber strap is saturated with epoxy and applied vertically to the wall.
- 3. Steel Bracket Anchoring: The straps are mechanically anchored to the top floor joists and the concrete slab below using a secure steel bracket system.
- 4. Strategic Placement: Straps are typically installed every 4 feet, beginning 2 feet from corners.
This creates a high-tension reinforcement grid that resists further bowing—without adding bulk to your basement or disrupting your home.
Benefits of Carbon Fiber Straps for Basement Walls
- Non-invasive: No excavation, no jackhammering
- Low profile: Slim finish that can be painted over
- Superior strength: 5x stronger than steel in tension
- Corrosion-resistant: Will not rust, rot, or deteriorate
- Fast installation: Most jobs completed in 1–2 days
- Permanent results: Designed to last the life of the structure
When installed by our expert team, carbon fiber strapping offers a maintenance-free, long-term stabilization solution you can trust.

“Anchored Walls did anchors and a full water-proofing system on my dad’s lake house. They were so great to work with from their sales team (Matt), to their front office (Maddy & Deb), their production manager (Lucas), and the foreman and his crew (Kyle & Sopheak). Their GM, Brad, even checked in to make sure everything…”

Frequently Asked Questions
Why is there mold in my crawl space?
Mold is a result of excessive moisture in the crawl space of your home. It’s very important that you take care of a moldy crawl space problem as soon as you notice that something is wrong. If left untreated, mold can cause a number of problems for the structural integrity of your home, as well as your family’s health. If you don’t repair your foundation, water will eventually seep in. This causes an assortment of additional problems for the structural integrity of your home.
How much does foundation repair cost?
According to This Old House, most foundation repair projects range from $2,000 to $10,000, depending on the size of the home, the type of foundation, and the severity of the damage. Small crack repairs may fall near the lower end, while structural issues that require stabilization or piering will be higher. Every home is different, but a professional inspection can help identify the most cost-effective path forward.
Are foundation cracks serious or just cosmetic?
Some small, vertical cracks may be normal settling, but if a crack is widening, leaking water, or forming a stair-step or horizontal pattern, it could signal a structural issue. It’s always best to have cracks professionally evaluated to determine whether repair is needed.
If I don't repair my foundation, what could happen?
If you don’t repair your foundation, water will eventually seep in. This causes an assortment of additional problems for the structural integrity of your home.
What causes foundation problems in the first place?
Most foundation issues are caused by changes in the soil around your home. Drought, heavy rain, poor drainage, and construction on improperly compacted soil can all lead to movement under your foundation. Over time, this movement creates stress on the structure and leads to cracks, shifting, or settling.
