FAQ
What is RAAC?
Reinforced Autoclaved Aerated Concrete is a lightweight, precast concrete used in construction from the 1950s to the 1990s. It has since been identified as a structural risk, particularly as it ages, because it can deteriorate without visible warning signs.
Where is RAAC typically found?
RAAC was commonly used in schools and universities, hospitals and clinics, offices and public sector buildings, housing developments, and military and MOD sites — often in roof planks, floor slabs and wall panels.
Why does RAAC need to be removed?
RAAC has been classed as potentially dangerous due to its tendency to fail suddenly, particularly when exposed to moisture or poorly maintained. Authorities including the DfE and NHS England have advised urgent assessment and, in many cases, removal and replacement.
Is your RAAC removal compliant?
Yes. We remove and dispose of RAAC in compliance with HSE guidance and site-specific safety plans, with full project management to minimise disruption.
