Concreate Foundation Cracks, What Do They Mean?

When you see a crack in your concrete slab or wall, generally your first assumption is something has been done wrong–but that’s not always the case. Concrete cracks are very common, some are even inevitable, but let’s review them:


Floor cracks in concrete slabs are relatively common and usually not worrisome on a structural level. They should be repaired to prevent common issues like moisture, insects, and damage from seeping through. When floor cracks leak, it is usually caused by hydrostatic pressure or a high water table. Therefore, sealing the crack will redirect those issues elsewhere.


Usually, a diagonal or vertical crack in the foundation wall is the result of settling in the concrete foundation and is quite common in new construction, especially if your home is built on a hill or your home has rapidly deteriorating soil conditions because of drought or heavy rainfalls. They usually run vertically or diagonally, are often located in the middle section of walls and are less than 1/8 in wide.

Frequently you will find vertical cracks in block foundations. If the crack is located closer to a corner and is wider than 1/8 in, it is probably not due to shrinkage but indicates a more serious foundation issue. It is recommended you call K & S Contracting to get it inspected as it may be a cause for concern.


Horizontal cracks that run across your foundation and/or walls are some of the most serious types your home can suffer. They indicate a severe issue with your foundation’s integrity that must be looked into.

Most horizontal cracks are caused by excessive water pressure from outside. In addition to other sources of pressure such as soil movement, it has the potential to impact your foundation’s integrity. They tend to expand and ruin the slab itself, possibly even causing it to collapse.


Stair step cracks are among the most common foundation cracks. These cracks are a clear sign of a problematic foundation. Typically, stair step cracks in a block foundation are a result of bowing walls. These cracks will be found toward the corners of the foundation, and are often found with a horizontal crack. In a block foundation, stair step cracks may also be found on the outside of the home. Stair step cracks always require further investigation in order to keep your home safe and supported.
