Foundation Wall Cracks

Cracks in foundation walls are often indications that the footings are failing. The cause may be that the footings were not poured to the proper depth, the reinforcing steel is missing, undersized or the soil supporting the footing is not stable. When significant cracks are discovered in a foundation wall a structural engineer or specialty contractor should be hired to investigate the cause and determine a solution to the problem. Vertical cracks appearing on the outside of a foundation wall are usually an indication of footing failure issues.
