Why Foundations Move in DFW
Foundation movement in the Dallas–Fort Worth area is mostly a soil story. The clays under most of the Metroplex change volume with moisture, and a slab poured on top of them rides that movement up and down through the year. These pages cover the mechanism, the regional differences across the Metroplex, and the things around a house that make it better or worse.
These pages cover why movement happens, metro-wide. What repair a given problem calls for belongs on the service pages, and how conditions differ in your specific suburb belongs on that city's page.
Causes
Why Clay Soil Moves Foundations
Foundation movement across most of the Dallas–Fort Worth area is a soil story before it is a construction story.
Causes
Poor Drainage and Foundation Movement
Expansive clay only moves when its moisture changes, and around a house the largest thing changing it is where the water goes.
Causes
Drought, Heavy Rain, and Foundation Movement
Foundation symptoms in this region tend to arrive on a schedule: late in a dry summer, or shortly after a long dry spell finally breaks.

Symptoms mean more in combination than alone. The check weighs them together and is honest when nothing needs doing yet.
