Recently our experienced workers started with concreting works at tunnel Diez, which is a road tunnel in the federal state of Rheinland-Pfanz in Western Germany. The tube is 330 m long with cross section of approximately 50 m2. After completion the tunnel will reduce road traffic in the town of Diez. Our scope of works is concreting of different single blocks of the bottom, the side walls and the vault section. We expect to use more than 10.000 m3 of concrete.
