Causes of Foundation Settlement

Foundation problems are most often caused by unstable soil. Many houses are built on relatively loose fill dirt—soil that has been disturbed during the building process. The fill dirt under a house settles over time. Unfortunately, if one part of the house settles more quickly than another, stresses in the foundation and structure develop. These stresses lead to cracks in the foundation, cracks in internal walls, and buckling or leaning foundations. Excessive ground or storm water entering the fill dirt near the house exacerbates the problem.
