Foundation Conditions in Dallas
Dallas is built on Blackland Prairie clay - consistently ranked among the most expansive soils in the United States. This dark, heavy clay expands significantly when wet and contracts sharply in summer droughts, cycling foundations through stress with every weather pattern change.
Dallas experiences hot, dry summers punctuated by intense storm events. This wet-dry cycling is the primary driver of foundation movement for the roughly 1.3 million homes in the metro area.
Common Foundation Types in Dallas
The vast majority of Dallas residential foundations are post-tension concrete slabs. While engineered specifically for expansive soil conditions, these slabs still shift, crack, and settle - especially homes built before 1990 with less sophisticated drainage design.
Most Common Foundation Problems in Dallas

- Stair-step cracks in brick veneer
- Interior drywall cracking
- Sticking doors and windows
- Plumbing slab leaks
