Waler Beam System for Bowed Basement Wall Repair
Severely bowed or leaning foundation walls are often caused by hydrostatic pressure—when water-saturated soil expands and presses against the outside of the foundation.
The Problem: Excessive Bowing or Wall Shear
Severely bowed or leaning foundation walls are often caused by hydrostatic pressure—when water-saturated soil expands and presses against the outside of the foundation. Without interior support, walls begin to curve inward, develop horizontal or stair-step cracks, and in more advanced cases, shear along mortar joints.
This damage is most common in concrete block walls and can progress rapidly if not properly addressed. The Waler Beam System is engineered to resist this pressure and restore structural strength to failing walls.

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.

The teams did an excellent job. Walker, Sopheak, Brad, Deb were great to work with. The anchors are very solid, well engineered.

How the Waler Beam System Works
- - Heavy-duty steel beams are installed vertically along the interior wall, spaced approximately every 4 feet.
- - Each beam is mechanically anchored at the top and bottom, locking it tightly into position.
- - For unfinished basements without a slab, beams are set into a concrete-filled trench 2 feet from the wall and 3 feet deep—creating a solid internal footing.
Our system is designed for residential and commercial use and works with a wide variety of wall materials—including block, concrete, and wood foundation walls. Whether your floor joists run parallel or perpendicular to the beam location, the Waler Beam System can be adapted to your structure.
Once installed, the beams create full-height stabilization, stopping movement and preventing further bowing or deformation.
Compatible with Wall Anchors and Interior Waterproofing
The Waler Beam System is engineered to work in tandem with our Wall Anchor Repair System, using interior beam bracing along with exterior tensioning to provide combined lateral and vertical stability. When walls are severely bowed or sheared, this combination provides a powerful, long-term solution.
In cases where wall movement is caused by hydrostatic pressure, our Waler Beam System is also fully compatible with our Interior Drain Tile Waterproofing System, as well as our Basement Encapsulation Solution depending on the repair strategy demand. This allows us to address both the structural damage and the underlying water pressure that caused it—offering complete protection from future foundation issues.

“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.
