Under construction

Unsuccessful foundation repair

Unsuccessful; foundation repair is not at all unusual in North Texas and other areas of expansive soils.

Signs of “foundation damage”  usually consist of cracks in sheetrock, hard floor coverings, bricks and in the grout between bricks or stones. Also doors and windows out of square, cabinets pulling from the wall ceilings or floor. Sometimes we see fireplace movement or external column movement.

Just about anything that is in, or part of, or is attached to a structure, that is not supposed to move but does, is considered foundation damage.That is damage caused by the foundation moving and not necessarily damage to the foundation.

The above “signs of foundation damage” are the result of the foundation moving. The degree of “damages’ is usually based on the degree of movement experience by the foundation.

Foundations usually move for a few general reasons. A major reason would be a fairly severe earthquake. An earthquake may cause anywhere from very minor, to catastrophic damage. Earthquake damage can often be mitigated by specific building codes required in areas know for quakes.. This kind of structural damage may occur  due to explosions, possible hurricanes or other trauma affecting the soil.or the structure.  Heavy, structural damage, such as above,  usually require some sort of piering, or added structural support.

Piers or additional support are also usually required when foundation damage is the result of a sinkhole, mud slide or other withdrawal or loss of an extreme amount of support soil.and structural damage has occurred.

In areas of expansive soils where strong earthquakes, sinkholes and mudslides are extremely rare, such as North Texas, the soil is the problem but not to the degree as mentioned above. In these areas, the soil shrinking and swelling under the foundation may cause  the volume of the soil  under a structure to ow and shrink providing different amounts of pressure or support under different areas of the foundation, in effect causing the slab or foundation to flex and actually force the foundation and in turn the building to change form slightly. Usually not enough to “damage the foundation but to cause areas of the home to be distorted to some degree. In other words the foundation is designed to be able to flex while the home is not. Where soils change volume under the foundation the foundation can adapt and the house will not.

That’s what “foundation damage”.in mostly about in areas of expansive soils.

Now the question is what can be successfully done to restore the structure, the foundation and the building, back to near “as built” and keep it there?
