Couvin bypass

We installed a total of ± 5500 m² of VNWALL and 500 m of railings along the Couvin outer ring road. The two 215-m tunnels are now equipped with sound walls on both sides, greatly reducing noise from the passage of cars and trucks. Two areas of 108 m and 83 m outside the tunnels were also equipped with our acoustic systems, ranging in height from 5 to almost 9 metres!
