Once a foundation is in place on the soils of South and Central Texas, it is subject to all the climate conditions and the resulting variations that can result. While there is no “magic bullet” once a foundation is set down, there are three things that homeowners can do to reduce the likelihood that there will be problems down the road. It is important to stress here, these are measures that will reduce the likelihood, they are not guaranteed to prevent problems.
These measures are directed at the control of water. The majority of soils in South and Central Texas are clays that react with water to varying degrees. When water is added to these soils, the result is not just mud, the clays actually attract and hold the water, and water being incompressible, they will lift a foundation. Conversely, if the soils become dry, they will allow a foundation to sink. The name of the game is consistency.
