Wall Anchor Systems for Bowed Foundation Walls
Poor exterior drainage or negative soil grading can cause water to collect around your foundation.
Why Walls Bow — and Why It Matters
Poor exterior drainage or negative soil grading can cause water to collect around your foundation. As that soil becomes saturated, it expands and pushes laterally against basement walls. Over time, this pressure can lead to cracking, bowing, or even structural failure if left unaddressed.
If you’ve noticed walls curving inward, developing horizontal or stair-step cracks, or shifting over time, a professionally installed wall anchor repair system may be the most effective long-term solution.

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.

How Our Wall Anchor Repair System Works
- - Anchors are installed from inside your basement and driven into stable soil outside the wall.
No large excavation is needed—minimizing disruption to your yard or landscaping. - - A steel rod connects the interior wall plate to a buried exterior anchor plate.
The connection applies counterpressure against the bowing wall to stop further movement. - - Over time, the system can be gradually tightened.
During dry weather, the adjustable torque system allows us to slowly pull the wall back toward its original position. - - Engineered for strength and precision.
Our system includes custom hardware designed to prevent overtightening, improve torque accuracy, and minimize stress on your foundation walls.
Reverse Wall Anchor Installation
In special cases—such as frost foundations, walk-out basements, or garage walls on slopes—the exterior wall may lean outward or separate from the floor slab. For these conditions, Anchored Walls installs Reverse Wall Anchors, which operate in the opposite direction of traditional wall anchors.
- Anchors are installed from outside the structure into the interior, allowing control over walls that have shifted outward.
- Exterior soil is excavated, and anchor rods are inserted through the wall.
- Interior wall plates are installed to create a pulling force that brings the wall back into alignment.
- When needed, interior slab excavation may be performed to aid in straightening.
This approach is ideal for walls where the entire wall plane is tipping away from the foundation, or where block shear failure is visible.

“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.
