Expansive Clay in Wylie, Texas
The ground moves here — and so do foundations. We engineer stability.
Why North Texas clay soils demand precision
Wylie and much of DFW sit on highly expansive clays (“black gumbo”). These soils swell when wet and shrink when dry, creating continual ground movement under homes, pools and flatwork.
Common issues
- Swimming pool movement and tilted/sinking decks
- Structural damage and cracked slabs
- Foundation settlement and uneven floors
- Poor drainage that worsens expansion cycles
How we stabilize
- Moisture conditioning & density control during compaction
- Proper grading and drainage slopes
- Engineered helical piers and underpinning
- Verification via compaction tests and torque/load monitoring
