They shrink and swell art

Many soils contain clay minerals that absorb water when wet (making them swell) and lose water as they dry (making them shrink). This ‘shrink–swell’ behaviour is controlled by the type and amount of clay in the soil and by changes in soil moisture content related to rainfall and local drainage. This shrink–swell variation can cause ... WebDue to the physical and chemical properties of some clays [4] (such as the Lias Group) large swelling occurs when water is absorbed. Conversely when the water dries up these clays contract (shrink). The presence of these clay minerals is what allows soils to have the capacity to shrink and swell.
