Council housing tenants on an estate built using reinforced autoclaved aerated concrete (RAAC) say they've been given no information about the safety of their homes.
The 18-home Knights estate in Basildon, Essex, was the first example of Siporex (another name for RAAC) being used for housing in the UK and is still standing.
Built in 1962, it now contains a mix of social housing and privately owned homes. When we visited, openDemocracy was shown examples of cracks in concrete on external walls by one tenant. She said: “There’s a metal bit sticking out and a massive crack and you can see through to the outside from our house. If we’re inside you can actually see daylight.”
