A guide to assessing existing roofs for the addition of solar panels

Learn how to identify, assess, manage and remediate reinforced autoclaved aerated concrete (RAAC) defects in buildings.

This report provides further guidance on the critical risk factors associated with RAAC panel construction. It includes a proposed approach to the classification of these risk factors and how these may impact on the proposed remediation and management of RAAC.

This free 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.
