Foundation movement or damage is almost always a result of the soil expanding under the structure, or less often the soil contracting and/or the loss of soil around the foundation. The key to preventing, stopping and often reversing the movement/damage is controlling that soil movement. Because there is often less profit in correctly addressing the problem than there is in installing piers, PIERS are OFTEN installed and are THE REASON for a majority of FOUNDATION REPAIR failures. I'll explain how to avoid these problems and how to get the correct repairs.

Not much you can do about earthquake movement or sinkholes, but erosion,  soil expansion and contraction can usually be controlled. 

Soil expansion, soil contraction and erosion can usually be dealt with. Each cause of foundation movement/damage has a specific solution that is not ideal for other types of foundation damage. 

Piers are usually, at best, an extremely expensive last resort and when piers are needed it is crucial to find a contractor that uses the piers that best meet your needs.

I've spent forty years studying foundations in expansive soils and there is not much that I haven't seen. Call me now for general information or save my number for later when the damage increases. For specific problems I can come look to the property and  give you detailed information and direction.
