Bowing Basement Wall Repair in Atlanta

Bowing basement walls can be an indicator of serious foundation problems, but can sometimes be difficult to spot. Foundation walls often move inward due to expansive soils and hydrostatic pressure, both of which place constant pressure on your foundation, crawl space, or basement walls. This pressure forces them to bow, buckle, or bulge inwards.

How do you know if you’re in need of a basement or foundation wall repair?

Here are some key signs that your bowing basement walls are in need of repair: 

  • Horizontal cracks or stair-step foundation wall cracks
  • Signs of inward movement, bulging or buckling foundation walls
  • Walls leaning at the top or sliding in at the bottom
  • Presence of expansive clay soils 
  • Evidence of hydrostatic pressure

Although these are all signs of bowing basement walls, they can also indicate foundation settlement or other structural issues. At AquaGuard Foundation Solutions, we offer free foundation inspections, during which our foundation experts will accurately identify the cause of your home’s foundation problems and basement wall bowing.

What Causes Basement Walls to Bow?

Before searching for repair solutions, it’s important to understand what’s causing your basement, crawl space, or foundation walls to bow. When you know the root cause of your foundation damage, you can find the best, most permanent solution for repair. 

With that said, the most common cause of bowing basement and foundation walls is unstable soil. Soil places constant pressure on your foundation walls—though the extent of this pressure can vary depending on soil conditions. The following soil conditions can cause excess pressure on your foundation walls: 

dry and wet clay soil

How much does moisture affect clay soils? These two clay samples started out exactly the same in size, weight, and composition. The sample on the right was allowed to dry out, while we kept the one on the left moist. If a small sample of clay can gain this much volume when it gets wet, just imagine how dramatic the changes are in the soil around your home!

  • Excess moisture and oversaturation: Poor exterior drainage and faulty gutters and downspouts can lead to the oversaturation of the soil surrounding your foundation. When soils become oversaturated, they can exert a force on your foundation walls known as hydrostatic pressure. Hydrostatic pressure not only causes walls to buckle and bow—it can also cause water damage and basement leaks. 
  • Expansive clay soils: The type of soil we have here in Northern Georgia is known as Georgia Red Clay. It’s an expansive soil, meaning that it expands under wet conditions and shrinks in drought. This means that proper exterior drainage is even more important to preventing bowing foundation walls. 
  • Frost heave: In the winter, soils fluctuate between freezing and thawing. When freezing temperatures penetrate the ground, moisture in the soil forms ice structures. These ice structures force the soil to shift, thus causing foundation wall movement. 

How Do You Fix a Bowing Basement Wall?

At AquaGuard, our preferred method of bowing wall repair is installing foundation wall anchors. The Foundation Supportworks Geo-Lock™ Wall Anchor system straightens walls by anchoring to stable, hard-packed soil beyond your home and bracing the foundation wall. This stops the inward movement entirely. Then, over time, these anchors can be tightened to move your foundation walls back to their original position.

Foundation wall anchors can repair many bowing wall problems. Soil anchors are placed in the ground outside. Steel rods attached to soil anchors extend through the foundation wall and wall plates. Wall plates distribute clamping pressure. Tightening nuts on the threaded ends of the rods stabilizes the wall for a permanent solution.

Advantages of Geo-Lock™ Wall Anchors:

  • Made with galvanized steel to prevent corrosion
  • Include a 25-year warranty against manufacturing defects, as well as an in-house quality and performance warranty
  • Hide-A-Way™ Wall Anchor Covers help conceal wall anchor access points

Repairing Bowing Walls Using Wall Anchors

To repair bowing walls using our warrantied wall anchors, our foundation contractors perform the following six steps:

  1. Dig Holes for the Earth Anchors: Upon arrival, our foundation contractors will provide a proposal that shows the location of each earth anchor that will be installed in your yard. The location of each earth anchor is determined to maximize system effectiveness. Prior to beginning the installation process, our contractors will lay a sheet to protect your lawn and landscaping and carefully remove sod from your lawn. Then, we will use a power auger to make each earth anchor hole. 
  2. Prepare the Foundation Wall: After excavating the earth anchor hole, we will core a small (1” diameter) hole through your basement wall. A steel anchor rod will then be driven through the wall and soil. This steel anchor rod will extend through a hole in the center of the earth anchor. 
  3. Attach the Earth Anchor: After the anchor rod is secured to its earth anchor, these assemblies are buried in the ground at each hole drilled earlier in the process. 
  4. Mount the Wall Plate: After the earth anchors have been installed, our contractors will mount a wall plate over each anchor rod that protrudes from the basement wall. We will screw a large nut to the threaded end of the anchor rod, securing each wall plate. This also serves to stabilize the wall as the nut is tightened. 
  5. Restore the Landscaping: Once the wall plate is mounted, we will begin our cleanup process. We take pride in leaving every job neat, clean, and free of landscaping damage and debris. We will fill holes completely with dirt saved from earlier in the installation process and will tamp filled areas to ensure soil won’t depress over time. We’ll replace all sod, ensuring it is blended with surrounding grass for a seamless landscape restoration. 
  6. Tighten wall anchors: In addition to stopping the inward movement of foundation walls, Geo-Lock™ Wall Anchors also give you the opportunity to straighten your foundation walls over time. By significantly straightening, and sometimes returning walls to their original position, you restore the value of your home.

Other Ways to Fix Bowing Basement Walls

In situations where the yard outside of a home is not accessible, it may not be possible to install a wall anchor system. At AquaGuard Foundation Solutions, we install our PowerBrace™ Foundation Wall System when wall anchors aren’t an option. The PowerBrace™ Foundation Wall Repair system is a patented foundation repair solution designed to stabilize and straighten bowing basement, foundation, and crawl space walls. The PowerBrace™ is an I-beam system that has several advantages over traditional “old school” systems, including its rust-resistant zinc coating and design.

What NOT To Do When Repairing Bowing Walls

A foundation repair is a big job—something you definitely want to do only once! When you’re repairing your foundation, beware of expensive options that will not actually fix your bowing wall problem—and watch out for quick solutions that just don’t work. When dealing with bowing walls, total foundation replacement may be suggested. To undertake a job like this, you have to excavate the entire perimeter of your foundation—including gardens, shrubbery, sidewalks, and other landscaping. Next, the house is jacked up, and the floor slab and foundation walls are removed. Finally, the foundation is rebuilt, the house is repositioned, and the soil is replaced.

This solution is extremely disruptive, expensive, and time-consuming. What’s worse, it’s not really addressing the issue. Your foundation isn’t the problem—the soil is! When you’re done building that brand new foundation, you can count on the soil to damage it just like it did before. If you’re going to invest money in repairing your foundation, choose the solution that is not disruptive and will be warrantied for the life of the structure.

Wasting time and money with total foundation replacement. This extreme repair option damages the yard and requires the house to be placed on temporary supports. It’s also expensive, time-consuming, and likely will result in the same issue again down the road.
