It is a most disconcerting fact that certain soils have not 'read' the published theories. Several theories exist relating to the expansion of clays and to the prediction of swell pressure. Swell pressure is often defined as the vertical overburden pressure which will prevent the clay from expanding when it is wetted. The different methods used to measure swell pressure, however, give very different values.
