Description
Geohazard assessment of the shrink-swell potential of geological deposits, primarily clays, mudstones, and shales. The methodology integrates BGS digital stratigraphic linework, geotechnical properties, and expert knowledge of formation behavior. The dataset is produced by the British Geological Survey and was last updated in March 2026.
Use Cases
Map regional subsidence risk using shrink-swell potential classifications of clay, mudstone, and shale deposits.
Correlate geotechnical properties with geological formations defined by BGS digital stratigraphic linework.
Support infrastructure planning by assessing natural hazard susceptibility based on expert knowledge of deposit behavior.
Strengths
Produced by the authoritative British Geological Survey (BGS).
Methodology integrates digital linework, geotechnical data, and expert knowledge.
Last updated in March 2026, indicating recent maintenance.
Limitations
The dataset has been superseded and is now part of the broader GeoSure product suite.
