Common Crack Patterns
- Vertical or horizontal cracks that exceed ¼ inch.

- Cracks that follow a line of a foundation wall.
Why Batavia's Soil Matters
Batavia sits on a mix of clay and loam soils. Clay expands when wet and shrinks when dry, causing differential settlement. Understanding local soil behavior helps predict where and how a foundation may fail.
Assessment Process for a Professional Repair
1. Visual inspection of exterior walls and interior floor levels.2. Soil analysis and moisture testing.3. Load‑bearing wall and footing evaluation with a structural engineer.4. Development of a repair strategy: underpinning, slab jack, or pier installation.
Underpinning vs. Piering
| Method | Typical Use | Estimated Cost |
|---|---|---|
| Underpinning | Extends existing foundation to deeper, stable soil. | $4,000‑$7,000 |
| Piering (Concrete Pier) | Supports and lifts the structure from below. | $3,500‑$6,000 |
