Foundation problems are nearly always caused by one (or more) of the following:
- Too Much Water. When the soil around the foundation of your walls swells, usually due to heavy rains, it exerts additional pressure on your walls, called hydrostatic pressure. This pressure can weaken your foundation’s structure.
- Not Enough Water. If your area is experiencing a drought, the soil around your foundation will shrink and pull away from your foundation walls. As the soil moves, your foundation walls may not have the required support and can crack.
- Surrounding Soil. Similar to water issues, expansive and consolidating soils, like clay soil, can affect your home by expanding and constricting. Expansion can cause upheaval (your foundation going up), while constriction can cause settlement (your foundation sinking).
- Poor Drainage. If the area surrounding your home has poor drainage, it’s likely to affect your foundation.
- Poor Preparation. If the contractor who built your home did not prepare the soil before building, you’ll likely experience settling.
- Poor Construction. If your home was built with substandard techniques, your foundation could experience shifts or cracking.
