he gypseous soil is a soil which has enough gypsum content to change or affect its engineering properties. Gypseous soils are usually stiff in their dry state due to the cementing action provided by gypsum, but great loss of strength and pronounced increase in compressibility occur when gypsum is dissolved by partial or full saturation.
