Compared to other rooms in the house, basements are particularly vulnerable to cracks; this is primarily because of their location. While proper installation and precautionary measures can prevent major problems, environmental issues and accidents can still create cracks. Knowing the shape and direction of the crack can reveal the source of the problem and which type of basement crack repair you need. Here are the most common types.

Identifying Basement Wall Cracks

Vertical

Often caused by the concrete curing process, vertical cracks are common and a frequent reason for basement crack repair. Tiny, imperceptible ones don't generally cause concern unless they start to grow. If they widen, they’ll eventually make it possible for moisture to seep through. To prevent this and the subsequent water damage, contractors fill it in with liquid polyurethane, which will expand throughout the entirety of the crack.

Horizontal

When the external soil absorbs too much water, it expands and presses against the basement walls. If there aren’t enough vertical reinforcements to guard against it or adequate drainage, it will ultimately create a horizontal crack. These will appear in the middle of the wall, at mid-height, since it bears the brunt of the weight. The wall may even bow inward. Basement crack repair specialists consider this to be more severe than vertical cracks; drainage and foundation stabilization may be necessary.

Diagonal

Unlike the first two, diagonal cracks have a variety of causes. It can be due to the foundation settling, concrete shrinking, or structural weak points between the basement and first floor. In basements made with concrete blocks, these could take on a stair-stepping appearance.
