Do you have cracks in your basement walls?

If so, you may begin to wonder what is the cause of these cracks and what do they mean for your home. Examine these common types of cracks to help you find out what issues you could be having.

Vertical Basement Cracks horizontal basement wall crack

Vertical cracks form as a result of shrinking concrete during the curing process. These cracks can sometimes be so small that you can hardly see them. The good new is, these cracks typically do not structurally affect the basement wall and can be common in homes. However, vertical cracks can let moisture in if the outside wall’s waterproofing isn’t able to span the crack. If moisture is being let in, basement waterproofing may be the solution. If the crack appears to be fairly large, it could be a problematic sign.

Horizontal Basement Cracks

If a basement wall appears to be bowing inward, it is possible that a horizontal crack could occur. Horizontal basement cracks are commonly found mid-way up a wall. Those cracks are formed as a result of stress from the ground pushing against it. If the wall appears to be straight, it is important to keep an eye on the size of the crack. Cracks that continually get larger can be a sign that the wall is beginning to bow. A foundation expert can evaluate the crack and provide further information as to what might be causing the crack.

Diagonal Basement Cracks

Diagonal cracks are common in basement walls. They are typically caused by settling issues as a result of changes in ground conditions underneath the foundation footings. Some of the different types of diagonal cracks include:

If you have any of the following diagonal basement cracks, it is best to contact a foundation expert.

Stair Step Basement Cracks

Stair step basement cracks are similar to diagonal cracks. However, these cracks only occur in concrete block basement walls. If you have signs of stair step basement cracks, it is best to contact a foundation expert.
