Selling a Home with Tree Roots Vegetation and Foundation Problems

Tree roots and shrubs can be the source of home foundation problems. Trees and shrubs withdraw large amounts of water from the surrounding soil and in areas of expansive soils that could be problematic.

The southern California area is home to large areas of expansive soils, which expand in volume when wet and shrink in volume when dry. This process of expansion and shrinkage is repeated many times and is called horizontal movement, vertical movement, uplift, upheaval and/or soil movement. Unfortunately for home foundations this soil movement is strong enough to crack and damage them. Usually the moisture content of the soil under the center part of the foundation remains stable. Usually it is the soil around the perimeter of the foundation that is alternately exposed to large volumes of water (rain) and long periods of drought. The repeated swelling and shrinkage of the soil will cause portions of the foundation to rise and to fall.

What happens when a large tree or dense shrubbery removes a disproportionate amount of water from the soil on one side of a home? Since the loss of water is not uniform around the entire perimeter of the home foundation, the soil near the tree or shrubbery will shrink to a disproportionate degree. The soil will then lose contact with the foundation and there is nothing but air between the foundation and the soil. The foundation will then “sag,” “sink,” or settle on that side of the home, and both the foundation and the home will suffer damage.
