Most texans have a high clay content and high water table. All clay is expansive and collapsible to some extent and widely varies according to conditions. When your soils are described as expansive or collapsible it is describing the propensity of the soil to swell or settle. Expansive or Swelling soil/clay is very dense. Collapsible or Settling soil is loose and will settle when there is a high concentration of water followed by drying.
If it is expansive aka Swell then you need to perform soil stabilization (if you excavate and the clay is black or really dark than you most likely have swell). If it is collapsible then you need to install piers to support your structure from settling. Soil injection stabilization is much cheaper than installing piers. Depending on your soil conditions you have three options...
