Reinforced Autoclaved Aerated Concrete (RAAC)

Reinforced Autoclaved Aerated Concrete (RAAC)

What is RAAC

RAAC is a form of lightweight concrete, although it still has the name concrete it is very different from the traditional concrete because of the way in which it was made.

RAAC was used from 1950’s to the mid 1990’s in schools, college and many other building constructions, so it may therefore be found in any school, college building if it was either built or modified during this time period.

The Government have been providing guidance and funding to schools and local authorities to manage the potential risks since 2018. However, new cases have made them less confident that buildings containing RAAC should remain open without extra safety measures in place.

If you think your building may contain reinforced autoclaved aerated concrete we strongly advise you to contract a Structural Engineer to complete a survey.
