If you’re shopping for a new home, you might notice cracks along the foundation in older homes. While these are the inevitable result of the home shifting, they may also point to a severe structural concern. Is there a substantial difference between horizontal and vertical cracks? In the eyes of home inspectors, the answer is yes—learn more about foundation cracks below.

Vertical Cracks

Concrete is an incredibly durable material under compression, but it will easily crack when exposed to tension. That’s why a concrete foundation supports the full weight of your home, but cracks as elements of the house and ground underneath shift. Most vertical cracks are no cause for concern, although they may permit rainwater to leak into the home. A professional will seal these cracks to prevent moisture from entering.

Horizontal Cracks

In contrast, horizontal cracks form when the foundation is bowing inward. Poorly drained or compressed soil pressing against the foundation usually causes this bowing. The heavy pressure will gradually push the center of the foundation inward, causing it to crack and eventually creating the risk of structural collapse. A home with horizontal foundation cracks will require extensive work to maintain the integrity of the structure.

To resolve the issue, a contractor may strap strong braces to the interior wall. For more extensive cracking, the space around the foundation is excavated to make room for anchors. Before you commit to a home with a bowing foundation, however, you should get the opinion of a home inspector to determine whether the house is worth it.
