Going underground

Join us on an underground adventure and enter the working environment of tunnel builders. There are over 1,300 kilometres of tunnels in Germany today – and more are planned. But what are working conditions like down there? We'll show you the different tunnel building processes and machines that are used and will make you more familiar with the many different attributes of shotcrete.
