Shrinking and swelling of the ground (often reported as subsidence) is one of the most damaging geohazards in Britain today.
The BGS is undertaking detailed geotechnical and mineralogical investigations into rock types that are prone to shrink and/or swell, and modelling their properties across the near surface. This research underpins guidance contained in the national GeoSure dataset, and is the basis for our responses to local authorities, companies and members of the public who require specific information on the hazard in their areas.
Studying the impact of trees and paved driveways on shrink–swell in urban areas.
What innovative research techniques are used at BGS and what results have been published?
New research published by the BGS has linked extended periods of low rainfall to high levels of shrink-swell subsidence claims on the clay soils of the South East of the UK
