GeoSure Soluble Rocks

The GeoSure data sets and reports from the British Geological Survey provide information about potential ground movement or subsidence in a helpful and user-friendly format. The reports can help inform planning decisions and indicate causes of subsidence. The methodology is based on BGS DiGMap (Digital Map) and expert knowledge of the behaviour of the formations so defined. This dataset provides an assessment of the potential for dissolution within a geological deposit. Ground dissolution occurs when certain types of rock contain layers of material that may dissolve if they get wet. This can cause underground cavities to develop. These cavities reduce support to the ground above and can lead to a collapse of overlying rocks. Dissolution of soluble rocks produces landforms and features collectively known as 'karst'. Britain has four main types of soluble or 'karstic' rocks; limestone, chalk, gypsum and salt, each with a different character and associated potential hazards. Engineering problems associated with these karstic rocks include subsidence, sinkhole formation, uneven rock-head and reduced rock-mass strength. Sinkhole formation and subsidence has the potential to cause damage to buildings and infrastructure. Complete Great Britain national coverage is available. The storage formats of the data are ESRI and MapInfo but other formats can be supplied.

Additional information: 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.
