Mechanised Tunnelling

Mechanised tunnelling

In the past Wayss & Freytag was significantly involved in the development of mechanized tunnelling techniques. For example, they initiated the support of the tunnel face by means of a bentonite suspension and air-cushion. With the so-called “slurry shield” this technique was brought to operational maturity. Wayss & Freytag is a pioneer of this technique and has in the meantime driven more than 150 km of tunnel using slurry shields. In addition, more than 80 km of tunnel were driven using earth pressure balance shields and 30 km using hard rock TBMs.
