Families protest over Raac homes worth ‘peanuts’

Reinforced autoclaved aerated concrete is a lightweight material that was used mostly in flat roofing, but also in floors and in walls between the 1950s and 1960s.

It is a cheaper, less durable alternative to standard concrete and has a lifespan of about 30 years.

Crucially, it is susceptible to structural failure and collapse when exposed to moisture.

It has been found in thousands of buildings across Scotland, including homes, schools and hospitals, sparking fears across the country.

Raac has been identified in council areas, including Dundee, West Lothian and Clackmannanshire, and is estimated to affect 2,445 homes owned by social landlords, according to a report , externalby the Scottish Housing Regulator.

Council tenants are currently having their Raac repair costs covered.

But many people who have bought their council houses said they felt abandoned by the government, with some facing repairs costs into the tens of thousands.
