Two of the UK’s biggest airports have confirmed that they have the collapse-pronce concrete RAAC at a number of locations on their sites.
RAAC is a lightweight concrete that was used during the 1950s and mid-1990s and has a “bubbly” texture. It was used mainly in roofs and sometimes in floors, according to the UK government. Both Heathrow and Gatwick have now confirmed they have locations containing the concrete which is prone to collapsing.
A London Gatwick spokesperson told the Mirror: “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.”
A Heathrow spokesperson added: “Industry has been aware and acting on the remedial steps that should be taken in buildings that contain this material.
