Abstract/Summary

Expansive Soils are soils that have the ability to shrink and/or swell, and thus change in volume, in relation to changes in their moisture content. They usually contain some form of expansive clay mineral, such as smectite or vermiculite, that are able to absorb water and swell, increasing in volume, when they get wet and shrink when they dry. The more water they absorb, the more their volume increases. For the most expansive soils volume changes of 10% are common (Chen 1988; Nelson and Miller 1992).
