BGS GeoSure: shrink����ʦ�swell subsurface is part of the BGS GeoSure range of natural subsidence products. It is a single data layer that identifies areas of potential shrink����ʦ�swell hazard that are underneath another solid formation and therefore hidden from the surface. It provides an indication of the presence of shrink����ʦ�swell-prone clays beneath other deposits (superficial or bedrock), down to a depth of around 10 m.
