Foundation Issues Caused by Trees
In our experience in South Louisiana, the biggest, single cause of foundation issues is differential settlement due to large trees. Large trees like Water Oaks and Live Oaks have extensive tap root systems that extract large amounts of water from the soil. Crepe Myrtles can also cause major damage because they grow very fast in a short amount of time. These trees, and many more like them, remove disproportionate amounts of moisture from soils under and adjacent to concrete slab foundations. In the end, one side of the house will tend to settle while the other side of the house won't, which can cause cracks in the foundation.
