Geotechnical expertise in Dallas
The Dallas region presents some of the most challenging soil conditions in the United States. Keller’s local teams have extensive experience addressing:
- Expansive clay soils that swell and shrink with moisture changes
- Variable subsurface conditions including limestone and sands
- Foundation movement and settlement risks
- Large-scale commercial and infrastructure development
Expansive clay soils in North Texas can undergo significant volume changes depending on moisture conditions, creating major challenges for foundation design and long-term performance. These conditions require tailored geotechnical solutions to ensure stability, durability, and performance throughout the project lifecycle.
