Since the risks associated with reinforced autoclaved aerated concrete (RAAC) hit the headlines recently, it has been a difficult time for many who fear there may be issues much closer to home
RICS' consumer guide on RAAC therefore aims to offer clear, impartial advice for anyone who suspects they live in a home that contains this building material. It covers what this building material is, why it was used, potential issues, and what to do if it is found in your home.
Consumers suspecting risk advised to consult professionals
The guide seeks to help homeowners make sense of a situation they may find themselves in through no fault of their own, educating and informing them so they can take a proactive approach to repair and maintenance work.
If someone suspects there is RAAC in their home, a chartered building surveyor competent in RAAC identification is well placed to confirm this and highlight other potential issues to be addressed during remedial maintenance.
When RAAC is present, the homeowner can appoint a structural engineer who can advise on suitable remedies. In some cases there may be no structural need to remove RAAC roofs or other elements; however, this can only be determined on a case-by-case basis.
The consumer guide and further information are available on the RICS' RAAC: Advice and FAQs page, which is recommended reading for all building surveyors.
