New information on buildings containing reinforced autoclaved aerated concrete (RAAC)

Updated: Apr 23

RAAC precast floor and roof components were used in the construction of a range of buildings, including schools, built between the mid-1950s and the 1980s.


Following a component failure HSE has previously highlighted the need for building owners and duty holders to identify buildings incorporating RAAC planks and take action where necessary.

The Department for Education has recently issued guidance for building owners (local authority, academy trust or diocese) on the management of buildings in England containing RAAC - Reinforced Autoclaved Aerated Concrete: Lightweight Concrete Roofs.

The guidance reinforces the need for schools to ensure that the condition of relevant buildings is assessed by a structural engineer and that effective monitoring and maintenance arrangements are in place to ensure on-going structural integrity.

The Local Government Association (LGA) has previously issued advice about reinforced autoclaved aerated concrete - Information on Reinforced Autoclaved Aerated Concrete (RAAC).
