Bowed basement walls occur when the walls of the foundation curve inward, forming what looks like a bow. If the bowing becomes too much, the walls may begin to crack or break. Basement walls are under constant pressure, so over time, this can occur. If it does, you need to get them repaired as quickly as possible to prevent further damage.

  1. What are some common causes of bowed basement walls? Bowed Basement Walls | Albertson, NY | A.M. Shield Waterproofing Corp.

Basement walls can begin to bow doe to the expansion of the clay soil that they sit in. This can occur because this soil can easily expand or contract depending on the level of moisture. The basement walls can also bow due to pressure being exerted on them by any water that accumulates in the soil. This is can occur if there is a problem with water drainage on the property. Finally, if the soil freezes and then expands, it can put pressure on the walls as the temperature changes.

Some foundations may bow simply due to the home settling in. No matter what the reason is, the constant pressure on the walls can cause it to bow, and you need to have it checked out.
