Less than 50 percent of these areas are underlain by soils with clays of high swelling potential. Expansive soils are soils that expand when water is added, and shrink when they dry out. This continuous change in soil volume can cause homes built on this soil to move unevenly and crack. Each year in the United States, expansive soils cause $2.3 billion in damage to houses, other buildings, roads, pipelines, and other structures. Expansive soils have the ability to drastically swell based on the amount of expansive minerals and moisture that is present in the soil.
