Cracked foundations can lead to structure problems, roof problems, problems with doors and windows, and even leaks in basement walls. Correcting structural and foundation problems can be very costly, and sometimes cracks in the foundation will be a warning sign of other structural problems in a house. Horizontal cracks in your basement foundation are serious. This type of crack is often due to the unbalanced pressure of the soil and hydrostatic water pressing against the foundation wall.
You may notice the base sloping inward and water leaking into the basement. Both block foundations and dumps can develop horizontal cracks. Horizontal cracks are more common in cinder block and brick foundations and may indicate a serious problem. Horizontal cracks run from wall to wall and occur when water pressure and unbalanced soil exert pressure on foundation walls.
These cracks often occur during a heavy rainy season, especially if you have poor drainage around your home. This pressure will cause the foundation walls to bend inward. The good news is that horizontal cracks can be permanently repaired with lifetime warranties and transferable warranties if you sell your home in the future. Check back in 6 months, if the crack has continued to grow, call a foundation professional for guidance.

Perforated concrete pillars stop lateral movement of foundations and stabilize homes built on slopes that experience problems due to soil creep. Shrinkage cracks are less likely to require structural monitoring and repair in poured concrete, as they would be expected to continue after initial curing. The activity of cracks in the wall of the foundation is difficult to determine for the same reasons as the activity of cracks in slabs.
Sometimes, soil pressure or differential settlement (when the supporting foundations of a house settle unevenly) can cause cracks in the foundation along the joints of mortar among the Several things can cause this type of foundation damage, including soil pressure outside the foundation and hydrostatic pressure that can cause basement walls to bend. Such cracks occur along the mortar joints and pose a serious threat to the integrity of your basement foundation.
