Be RAAC aware – Reinforced Autoclaved Aerated Concrete (RAAC)
Reinforced Autoclaved Aerated Concrete (RAAC) is a lightweight form of concrete. It is very different from traditional concrete, and because of the way it was made, it is much weaker.
This type of concrete was used in many building types (built or modified) from the 1950s until the mid-1990s including schools and colleges.
RAAC panels have deficiencies making them less robust than traditional concrete. This increases the risk of structural failure, which can be gradual or sudden with no warning. The sudden failure of RAAC panels is dangerous with potentially serious consequences.
A common application of RAAC is roof decks. There is additional risk created when the roof coverings are in poor condition as water ingress contributes to the deterioration of the RAAC planks.
Many schools will not know whether or not they have RAAC in their buildings, especially as it is often concealed by suspended ceilings or the surfaces have been heavily painted or coated etc.
Last year the DfE published guidance which outlines the steps schools should take on how to identify RAAC on their estate and what actions to take if it is present.

The DfE has also released a questionnaire for all schools, multi-academy trusts and local authorities to complete concerning the presence of RAAC and how the risks are being managed.
The deadline for the questionnaire is fast approaching on 28 February 2023.
