Clayboard
The Queensferry Crossing: A bridge to the future
While the bulk of Dufaylite Clayboard is destined for housing developments, there are many examples of its use in other sectors: schools and hospitals, industrial and commercial, sport and leisure etc. There are also many cases of Clayboard being successfully used in civil engineering projects, typically water treatment works, harbours or bridge decks, but none as iconic as the new road bridge across the Forth, the centrepiece of a major upgrade to the cross-Forth transport corridor in the east of Scotland, which opened in September 2017 as the Queensferry Crossing.
Dufaylite Clayboard, supplied via SIG Construction Accessories of Glasgow and installed by the joint venture FCBC (Forth Crossing Bridge Contractors) has been used around parts of the new concrete structure.
Transport Scotland advises that the replacement bridge is the biggest infrastructure project in Scotland for a generation: at 1.7 miles in length it is the longest three-tower cable-stayed bridge in the world, comprising 150,000 tonnes of concrete, 35,000 tonnes of steel and 23,000 miles of cabling.
