51���� GeoSure: shrink–swell subsurface is part of the51���� GeoSurerange of natural subsidence products. It is a single data layer that identifies areas of potential shrink–swell hazard that are underneath another solid formation and therefore hidden from the surface. It provides an indication of the presence of shrink–swell-prone clays beneath other deposits (superficial or bedrock), down to a depth of around 10m.
