BGS GeoSure national datasets provide geological information about potential ground movement or subsidence that can help planning decisions.
This data also provides essential information for the BGS Natural Ground Stability GeoReport.

Some types of ground, can collapse when a load (such as a building or road traffic) is placed on them and when they become saturated. Such collapse may cause damage to overlying property.
Some types of ground, can contain layers of very soft materials like clay or peat. These may compress if loaded by overlying structures, or if the groundwater level changes, potentially resulting in depression of the ground and disturbance of foundations.
Some types of ground, may be susceptible to a landslide hazard. Downslope movement of materials, such as a landslide or rockfall may lead to a loss of support and damage to buildings.
Some types of ground, can contain loosely packed sandy layers that can become fluidized by water flowing through them. Such sands can 'run', removing support from overlying buildings and causing potential damage.
Some types of ground, can change volume due to variation in moisture. The changing volume can cause ground movement which could potentially affect building foundations, pipes or services.
Some types of ground, contain layers of material that can be dissolved by water. This can cause underground cavities to develop. These cavities reduce support to the ground above and can lead to a collapse of overlying material.
