Slab Foundation Repair Warning Signs in San Antonio Homes
Knowing the early indicators of slab foundation damage is crucial for timely intervention.
San Antonio homeowners should be vigilant for the following warning signs:
- Cracks in interior or exterior walls, especially near windows and doors

How San Antonio’s Expansive Clay Soil Affects Slab Foundations
San Antonio’s soil is primarily composed of expansive clay, which can significantly impact slab foundation stability.
This type of soil absorbs water readily, causing it to swell and expand.
As the soil dries out, it contracts and shrinks, leading to a cycle of movement that can cause foundation settling, shifting, and cracking.
| Soil Condition | Effect on Foundation | Risk Level |
|---|---|---|
| Wet, expanded soil | Upward pressure, heaving | High |
| Dry, contracted soil | Gaps, settling, sinking | High |
| Stable, balanced moisture | Minimal movement | Low |
Areas in San Antonio with higher clay content, such as the northeast and southwest parts of the city, are more prone to foundation issues.
Homeowners in these areas should be particularly attentive to signs of foundation damage.
