Soil Terminology: Expansive Soil

Last updated 5 years ago

A home’s foundation supports everything from its plumbing to its electrical wiring, not to mention the walls and ceiling. However, soil supports the foundation itself, and it is far from stable. As the name suggests, expansive soil expands and contracts with changing moisture levels, resulting in severe uplift forces on the foundation. Expansive soil causes over $13 billion in structural damage annually, and is estimated to affect over half of all U.S. homes.

All soil exhibits some amount of swelling and movement, but expansive soil can exert thousands of pounds of pressure per square on the sides and corners of a home during wet weather. The only way to prevent foundation damage from expansive is to keep moisture levels constant around the foundation with proper drainage systems.
