Heathrow and Gatwick airports have both had the crumbling concrete found which has forced many schools to close across England.
The UK’s two busiest airports have said that they are aware there is reinforced autoclaved aerated concrete (RACC) and they have taken steps to remedy this issue.
RACC was used in buildings from the mid 50s until the 90s in public buildings including more than 1,000 schools.
Heathrow Airport said that RACC was found in Terminal 3 last year and temporary measures have been put in place.
In a statement, Heathrow airport said, “Industry has been aware and acting on the remedial steps that should be taken in buildings that contain this material.
“We, like many others, have been assessing our estate and will continue to mitigate the risk where this material is found.
“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.”
A Gatwick spokesperson also said, “We have a register of locations containing RAAC on the airport campus, which are closely monitored through a regular comprehensive structural inspection regime.
“Our most recent inspection in June 2023 did not present any concerns, and we will continue to monitor on a regular basis.”
