Homes in Aberdeen face evacuation due to crumbling Raac

Hundreds of homes in Aberdeen, Scotland, face evacuation due to crumbling reinforced autoclaved aerated concrete (Raac). Around 4 million non-residential buildings in the UK and some social housing used Raac, which has a lifespan of only 30 years. Aberdeen City Council is moving occupants to alternative accommodation at an initial cost of £3m. The council is considering rebuilding or demolishing affected homes. Last year, councils and housing associations were advised to review their stock for Raac.
