Minor cracks in concrete foundations
Minor cracks in concrete foundations are not uncommon, possibly indicating the need to repair a concrete foundation. This is because concrete shrinks as it heals.

These are usually thin, vertical cracks that show randomly throughout the foundation. They can range in length from two inches to the full height of the wall. If the concrete was mixed incorrectly or poorly, the cracks would get bigger. The degree and characteristics of cracking can also be affected by steel reinforcement’s use (or reduction). Shrinkage cracking will usually stop once the concrete is cured.
Foundation cracks in an older building should be a significant concern. In particular, look for cracks in the vertical walls that grow significantly in a short time. Although cracking can be the result of a settlement, it can also be an indication of more severe foundation problems.

This cracking is sometimes caused by loose soil or incorrect backfilling. Anyway, if you notice horizontal cracks in both places, contact a foundation contractor immediately, especially if the cracks get bigger over time.
