GeoSure Collapsible Deposits
The GeoSure datasets and related reports from the British Geological Survey provide information about potential ground movement due to six types of natural geological hazard, in a helpful and user-friendly format. The reports can help inform planning decisions and indicate causes of subsidence. The Collapsible Ground dataset provides an assessment of the potential for a geological deposit to collapse (to subside rapidly) as a consequence of a metastable microfabric in loessic material. Such metastable material is prone to collapse when it is loaded (as by construction of a building, for example) and then saturated by water (as by rising groundwater, for example). Collapse may cause damage to overlying property. The methodology is based on BGS DiGMapGB-50 (Digital Map) and expert knowledge of the origin and behaviour of the formations so defined. It provides complete coverage of Great Britain, subject to revision in line with changes in DiGMapGB lithology codes and methodological improvements. The storage formats of the data are ESRI and MapInfo but other formats can be supplied.

Geotechnical data abstracted from NGDC site investigation collection and entered into the BGS geotechnical database. Methodology may be revised in the light of new knowledge or customer feedback. Changes in DiGMapGB-50 base data will require periodic or continuous revision. ADDITIONAL_INFO 1 = Complete GB National Coverage, subject to revision in line with changes in DiGMapGB-50 lithology codes. Based on 1:50 000 DiGMapGB-50 linework. Methodology consistent throughout. Otherwise subject to logical consistency of DiGMapGB-50.
