This guidance provides identification and remediation solutions for Reinforced Autoclaved Aerated Concrete (RAAC) planks. RAAC has been used in building structures in the UK and Europe since the late 1950’s, most commonly as precast roof panels in flat roof construction, but in the 1990s structural deficiencies became apparent.

This report has been prepared to improve awareness of RAAC amongst the wider structural engineering community and share recent findings to assist those who are asked by clients to advise on the management and mitigation of RAAC panels. It is recommended that the reader also familiarises themself with the 2019 SCOSS alert and the other key references at the end of the report.
