Reinforced Autoclaved Aerated Concrete (RAAC) – update

Date: 14/09/2023

In accordance with the Welsh Government’s latest guidelines, the Council’s officers have been checking if RAAC (Reinforced Autoclaved Aerated Concrete) is present in school buildings within the county.


These assessments have been completed and we can confirm there is no RAAC in our schools.


Work to check the remainder of the Council’s building stock has begun and we will continue to work with the Welsh Government on the matter, following their guidelines.
