Various concerns have been raised about the use of a type of concrete in the construction of public buildings known as RAAC (reinforced autoclaved aerated concrete). RAAC is a lightweight material which was used mostly in flat roofing between the 1950s and 1990s.
Aberdeen City Council has been aware of concerns about the use of this product and has previously conducted a range of surveys and inspections of buildings to assess whether these buildings have this material present. This work has identified several properties which have RAAC within their construction.
We are currently reviewing the guidance in place and will be undertaking further inspection and testing works in the affected buildings over the next months.
