REVIEW OF EXPANSIVE SOILS

It has been estimated that the annual cost of damage from expansive soils in the United States alone is $2.3 billion. Of the three most prominent clay minerals--illite, bailinite, montmorillonite--the latter constitutes the most expansive type of clay soil. The current design practice for construction in expansive clay subsoil starts with a study of the site to determine the soil's characteristics. The appropriate correction action may include stabilization by chemical means, presaturation, compaction, and the design of engineered-type foundations, such as pier and grade-beam, and reinforced slabs. The relative cost of alternative designs should be evaluated in terms of the risks involved.
