RAAC is a lightweight, bubbly form of concrete that was often used in schools, colleges and hospitals from the mid 1960s to the mid 1980s.
More invasive surveys of our buildings have identified a section of RAAC in the roof of our maternity unit, in an older part of The James Cook University Hospital.
It is classed as low risk, which means there is little sign of deterioration or damage and there is no disruption to services.
Our regular inspections will continue to make sure there is no change in its condition, and it will be removed as part of the ongoing work to eradicate RAAC from the NHS estate.
None of our other buildings have been identified as containing RAAC.
