Expansive clay soils shrink when dry and swell when wet. Uneven moisture around a slab can lead to movement. A leak under or near the slab adds water to one area, which can make movement uneven.
- Watch for new cracks, sticking doors, and gaps at windows.
- Keep drainage sloped away from the house and gutters clear.
- Ask a foundation professional before following any watering plan; advice varies by home.
- Run a meter test if you see foundation signs; a hidden leak may be involved.
