WebVertisols Vertisols (from Latin verto, "turn") are clay-rich soils that shrink and swell with changes in moisture content. During dry periods, the soil volume shrinks and deep wide cracks form. The soil volume then expands as it wets up. WebMay 6, 2024 · High plasticity, excessive heave and high swell–shrink potential are the parameters used for identification of expansive soil made up of clay, shale or marl [ 1, 2 ]. Ground heave is the upward movement of the ground usually associated with the expansion of clay soils which swell when wet and shrink and when water evaporates from them [ 3, 4 ]. fitted industries
