Unsafe concrete in schools ‘just the tip of the iceberg,’ MP warns

Over 100 UK schools have been impacted by an update in government guidance warning of the risks of using reinforced autoclaved aerated concrete (Raac) after some classrooms were forced to shut to students. Experts warn the crisis could spread beyond the education sector, with healthcare settings, courts, and offices also potentially at risk. Officials and opposition parties are calling for clarity over the extent of Raac use across public sector buildings.
