A ground stability advice service has been launched by the British Geological Survey (BGS) to help reduce the risks associated with building developments on potentially unstable lands.

The service, called GeoSure, uses digital technology to identify natural subsidence hazards, and can be used throughout England, Scotland and Wales. The service is based on a computerised geological map of Britain, said BGS.

BGS said the service would help the construction industry discover areas where it was safe to build, helping to combat future subsidence claims.

BGS said the service would enable marginal land to be brought into productive use by identifying where appropriate precautions would allow building to take place on previously unstable land.
