GeoSure ground stability data product version 8

BGS GeoSure identifies, at 1:50 000 scale, areas of susceptibility and considers the following specific hazard processes that can occur in Great Britain: 1. Shrink–Swell: Swelling clays change in volume due to changes in water content; this can lead to movements (up or down) in the upper two metres of the ground, which may affect property foundations. 2. Landslides (Slope Instability): Slope instability occurs when particular slope characteristics combine to make the slope unstable. Downslope movement of materials (landslide) may cause damage to foundations, services or impact damage to buildings. 3. Soluble Rocks (Dissolution): Ground dissolution occurs when certain types of rocks, containing layers of soluble material, get wet and the soluble material dissolves. This can cause underground cavities to develop. These cavities reduce support to the ground above and can lead to a collapse of overlying rocks. 4. Compressible Ground: Some types of ground may contain layers of very weak materials such as peat or some types of poorly structured clays. These may compress if loaded by overlying structures, or if the groundwater level changes. This compression may result in depression of the ground surface, potentially disturbing foundations and services. 5. Collapsible Deposits: Some soils may collapse when a load (building or road traffic) is placed on them, especially if they become saturated. Such collapse may cause damage to overlying property or services. 6. Running Sand: Some rocks and soils can contain loosely packed sandy layers that can become fluidised by water flowing through them. Such sands can ‘run’ (flow), potentially removing support from overlying buildings and causing damage.

Statement

This dataset is derived from the BGS Geology v8 (DiGMapGB-50_V8), each new version of BGS Geology 50k prompts a new version of GeoSure. Version 8 (released 2018): New 1:50 000 geological mapping in 18 areas as well as data refinement associated with coastal areas and miscellaneous corrections to features across the country. Partially revised methodology for the Slope Stability (Landslides) layer incorporating new information on Quaternary Till deposits. Updated expert polygons extent in Dissolution layer to reflect new geological mapping. Methodology devised by the Natural Geohazards Project. Latest version, and earlier versions, are held in project files User Guide for the British Geological Survey GeoSure dataset: Version 8 available online https://www.bgs.ac.uk/datasets/geosure/ (Open Report: OR/17/050).
