Initial Assessment and Inspection
Professional contractors begin with a thorough visual inspection, measuring cracks, checking for uneven floors, and using laser levels to determine settlement severity. Moisture tests and soil analysis may follow to identify underlying causes such as expansive clay or poor drainage.

Diagnosis and Repair Planning
Based on the assessment, the contractor outlines the repair method—pier and beam, slab jacking, or wall anchors—tailoring it to the home's construction and soil conditions. A detailed estimate includes material, labor, and any required permits.
Common Repair Methods
Typical techniques used in White Settlement include:
- Helical piers: steel shafts screwed into stable soil to lift and support the foundation.
- Push piers: driven concrete or steel piers that transfer load to firmer layers.
- Polyurethane foam injection: expands beneath slabs to fill voids and raise the surface.
- Wall anchors and braces: steel rods anchored into deeper soil to stabilize bowing walls.
Execution of Repairs
Contractors excavate around the foundation, install the chosen piers or anchors, and use hydraulic jacks to lift the structure back to level. Once the desired elevation is reached, the piers are capped and the excavation backfilled. For slab jacks, foam is pumped through drilled holes, expanding to lift the slab.
Post‑Repair Evaluation
After completion, a second laser survey confirms that floors are level within industry tolerances (typically within 1/8 inch over 10 feet). The contractor provides a warranty outlining coverage for settlement recurrence and may recommend drainage improvements to prevent future issues.
Cost Considerations
Repair costs vary by method and severity. Below is a typical range for White Settlement:
| Method | Typical Cost | Best For |
|---|---|---|
| Helical piers | $8,000–$15,000 | Deep settlement, expansive soils |
| Push piers | $5,000–$12,000 | Moderate settlement, stable lower layers |
| Foam injection | $3,000–$8,000 | Minor slab settlement |
| Wall anchors | $4,000–$10,000 | Bowing walls, lateral pressure |
