Cracks in a foundation are some of the first signs you can use to determine if you need foundation repair, or at least an engineer inspection. However, not all cracks are created equal. Here we’ll explain the difference between vertical and horizontal cracks, as well as the reason why horizontal cracks in foundation are usually much more dangerous than vertical cracks.
Vertical Foundation Cracks
Vertical foundation cracks generally run up or down your walls, sometimes at a slight angle. They are usually less dangerous to your foundation, and can often be repaired quicker and at less cost. Vertical cracks in the foundation are also sometimes referred to as “shrinkage cracks” because they can occur because of concrete shrinkage. Sometimes vertical cracks can even be cosmetic only, but be sure to have them inspected by a certified repair engineer regardless.
Horizontal Foundation Cracks
Horizontal foundation cracks run across the foundation and usually span more than one support. Unlike vertical cracks horizontal cracks will not occur simply because of concrete shrinkage or other problems like water damage. They usually occur because of excessive outside pressure, such as shifting soil, water pressure, or other sheer forces to the foundation.
Horizontal cracks are much more dangerous than vertical cracks because they can quickly lead to total foundation failure. Even without total failure, they will likely begin to cause serious damage to the walls of your home as multiple supports in one area will likely already be compromised.
