1. Inadequately compacted soil. Your house may have been built on soil that wasn’t prepared appropriately to bear the load of your home.
2. Drainage problems. Water that drains near the foundation causes soil to swell, thereby shifting parts of the foundation which can lead to structural damage.
3. Unsteady moisture. Periods of wet weather followed by extended periods of dry weather cause soil to expand and contract at uneven rates, which stresses your foundation.
4. Roots from trees or other vegetation. Roots and vegetation near your home can create changes and damage to foundations.
5. Erosion. The stability of your foundation can be effected when homes are built on hills or other elevations.
6. Construction: Poorly constructed structure and structural damage created by contractors installing heating units, a/c units or water heaters, etc.
