DIG 241 Low-rise buildings on shrinkable clay soils: part 2
Volume changes in clay soils brought about by seasonal changes in soil moisture content and by the removal of soil moisture by deeply routed vegetation have caused widespread damage to low-rise buildings, especially following periods of low rainfall. Whether or not substantial shrinkage will occur on any given site is difficult to predict since it depends not only on the soil type, but also on many other factors. Of these the local groundwater condition, which can vary enormously over short distances, is probably the most important.
