This paper reviews the background and extent of the expansive soils problem in South Africa. The origin of expansive soils is discussed and indicators of heaving conditions which should be recorded during the site investigation are identified. An appraisal is given of the traditional and more recent methods of heave prediction and the selection of suitable foundation types is reviewed. Recommendations are provided for the design of stiffened raft foundations.
