Providing low carbon concrete solution for Gatwick station

We are supplying low carbon concrete to help transform Gatwick Airport station as part of Network Rail’s plans to upgrade and improve the experience of rail users.

To date we have supplied around 3,000m3 of low carbon concrete to main contractor Costain to refurbish the existing station concourse and build a second, bigger one which will create a new entrance into the airport.

The concrete, which contains 70 per cent Regen GGBS (ground granulated blastfurnace slag), provides the correct durability requirements while saving more than 500 tonnes of CO2 emissions over a standard concrete – the equivalent of 500 people making a return flight between Paris and New York.

Calvin Blacker, Costain’s design manager for the Gatwick station project, said: “Hanson was chosen as our materials supply partner due to its proven track record for innovation in lowering the carbon footprint of concrete within its supply chain.

“We have worked closely together to deliver concrete that meets the challenging requirements of the project while adding to its low carbon credentials.”

Network Rail’s plans will create more space for passengers, making the journey from train to plane easier, improving accessibility and supporting a more reliable train service. They will double the amount of space for passengers and support movement around the station and in and out of the airport.
