Two of the UK's major airports confirm that they have reinforced autoclaved aerated concrete (Raac)

The two busiest UK airports, London's Heathrow and Gatwick have both confirmed they have the porous reinforced autoclaved aerated concrete (Raac) which is at the centre of the school building controversy.

A spokesperson for Gatwick confirmed the airport carries out regular inspections on the Raac concrete at the airport and the last one was completed in June which did not present any concerns.  "We have a register of locations containing Raac on the airport campus, which are closely monitored through a regular comprehensive structural inspection regime."

London Heathrow said it was "assessing our estate and will continue to mitigate the risk where this material is found". Some areas of Terminal 3 have Racc and the airport's management had already put in mitigation measures to make it safe. The airport confirmed it had the means to keep it safe until "permanent solutions" were able to be introduced. A spokesperson added, "Passenger and colleague safety will always be our first priority, and we will continue to update stakeholders across the sector as our plans for permanent solutions progress."
