There are various cracks that you may discover in your foundation. Cracks are usually a result of your foundation’s response to the changes in soil around your home. While there are some cracks that are not worrisome, most cracks should be checked out by a specialist in order to be sure your home is safe.

Hairline cracks

Hairline cracks are typically no cause for concern. These are small, thin cracks that may be found near windows or doors. These cracks could be a relief joint. Sometimes these cracks are a result of the concrete shrinkage as it dries. It never hurts to have a specialist take a look at these cracks to ensure your foundation is stabilized.

Stair step cracks

Stair step cracks are among the most common of 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 brick foundation, stair step cracks may be found on the outside of the home. These cracks are typically a result of settling foundation. Regardless, stair step cracks always require further investigation in order to keep your home safe and supported.

Vertical cracks

Signs of a settling foundation can be seen in vertical foundation cracks. In addition to vertical cracks, tilting chimneys, jamming doors and windows, and cracked slab floors are also a common symptom of a settling foundation. Foundation settlement is natural. As the soil around the home settles, the foundation settles with it. Unfortunately, the soil and the foundation do not always settle equally. To restore the foundation to its original position and provide support Push Piers are often the best solution. Push Piers stabilize the foundation and provide permanent support for the home.

Horizontal cracks

Cracks that are horizontal in nature are often a result of a bowing foundation. Foundation walls bow inward due to high hydrostatic pressure in the soil. As the walls bow inward, water often leaks into the basement of the home. Bowing walls compromise the integrity of the home’s support. Geo-Lock Wall Anchors are often the best option to restore the walls to their original position and provide permanent support.
