Damage that expansive soils do to light buildings can often be prevented or mitigated by preconstruction soil treatment. Treatments of three kinds are described—reworking the soil, controlling its moisture content, and adding chemicals. The idea is to remove the expansive soil or minimize changes in water content, which is what causes the shrinking and swelling. For each of the three classes of actions, many alternatives are described.
