Basement Wall Crack Repair

Cracks in basement walls are a symptom of foundation settlement and damage. When small cracks are present, it could be a natural occurrence that happens during the curing process of the concrete. Usually, these types of cracks are harmless and aren’t necessarily a sign that there’s foundation damage. But if you are seeing large cracks, and they seem to be expanding with time, this may be an indication that your foundation is settling.  

At American Foundation & Waterproofing, our team of foundation repair specialists can offer a free inspection of your basement wall cracks and determine whether you have foundation settling or damage. We can also provide recommendations to repair the cracks and your foundation, including taking measures to prevent further damage.   

Causes of Basement Wall Cracks

If you’ve noticed cracks in your basement walls, it’s important to act quickly and identify the cause so you can address the issue before it gets worse. Our team can determine the best solution based on the root cause. Basement walls may show cracks because of one or more of the following problems:

Improper soil compaction: If the soil underneath your foundation wasn’t properly compacted when your house was built, it will settle over time due to changing weather patterns and the sheer weight of the structure it is supporting. As the soil shifts and settles, the foundation will settle unevenly, which causes excessive pressure on the basement walls.

Hydrostatic pressure: Heavy rain or melted snow can absorb into the soil and cause it to expand against the foundation walls. The walls will eventually bow or crack from the pressure as it builds over time.

Soil shrinkage: When soil shrinks or compacts unevenly, the foundation will settle in an irregular pattern. This can eventually lead to problems. With some areas exposed to more pressure than others, cracks can form in basement walls.

Soil erosion: As soil erodes around your home, rainwater can easily flow toward the foundation and cause irregular settlement. As the foundation settles, it can cause basement walls to crack.

Vegetation: Extensive root systems from trees, shrubs, and bushes can disrupt the concrete foundation and cause excess water to seep toward your home. Your basement walls may crack or bow because of this pressure.
