Foundation Problems

Foundation settlement and movement requiring foundation repair can be caused by building on expansive clay, compressible or improperly compacted fill soils, or improper maintenance around foundations.  Whatever the cause, settlement can destroy the value of structures and even render them unsafe.

Water is the basic culprit in the vast majority of expansive soil problems. Certain soils tend to swell or shrink with variations in moisture. The extent of this movement varies from soil to soil.  Those soils highest in clay content are generally more susceptible while those lowest in clay content are the least affected.  When unstable soils are used as a base for a foundation, the tendency for movement is transmitted to the foundation. Since soil movement is rarely uniform, the foundation is subjected to a differential or upheaval. The problem shows up in both slab, and pier and beam type foundations.

If all the soil beneath a foundation or slab swells uniformly, there usually is no problem. Problems occur, however, when only part of the slab settles. Then, the differential movement causes cracks or other damages.

Concrete floor and foundation repair contactors provide patented engineered services to repair a failed foundation.  If you think that there is a problem with your foundation, call a professional foundation repair contractor for an assessment of your property. They will be able to assess any damage that has occurred and determine the best plan for your situation.  This is definitely not a DIY type project.
