When cracks are seen in the walls, it is often a sign of foundation problems or damage. Sometimes the problem is due to foundation shrinkage, soil expansion, or settlement.

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.

The amount of shrinkage that will occur depends on several factors, such as the type of concrete used, the temperature at which it was poured, and how much water was used.
Shrinkage cracking
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. Cracks higher than the bottom can also be dangerous, especially if you find them near the tip of a brick wall.

Horizontal Cracks
Horizontal cracks in walls are sometimes the most severe type of cracking. In many cases, they can only be seen in crawl areas or basements. 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.
