National Assessment of Compressible Geological Deposits in Great Britain

GeoSure Compressible Deposits data from the British Geological Survey assesses the potential for ground compression under load. The dataset provides complete national coverage for Great Britain, identifying superficial deposits like peat or alluvium that may compress and cause subsidence.

Use Cases

• Model subsidence risk for construction planning by analyzing the distribution of compressible deposits like peat or alluvium.
• Inform infrastructure development by assessing the potential for ground movement in areas with soft materials such as clay.
• Support geological hazard mapping by integrating expert knowledge on the behavior of defined formations.

Strengths

• Provides complete national coverage for Great Britain.
• Based on BGS DiGMap (Digital Map) data and expert knowledge of geological formations.

Limitations

• Data is delivered in specific GIS formats (ESRI, MapInfo), requiring compatible software for analysis.
• The assessment is based on geological potential, not direct measurements of ongoing subsidence.
