Our main emphasis is the mechanical tunnel driving - a domain, in which we do not only dispose of a long experience and great professional know-how, but furthermore we can count on most modern technical equipment.
Our methods of excavation by driving:
- Open TBM (tunnel boring machine) driving and placing of the bottom with precast concrete components
- Special driving using shield TBM and placing of tubbing segments (hydro and muddy soil pressure balanced shield)
- Driving using road header excavators (TSM)
- Driving using pipe screen or jetting machines
- Conventional driving using drilling jumbos (drilling and blasting)
- Special drivings (construction by sections, shaft sinking etc.)
In our central location of Klus near Balsthal with railway connexion, we produce precast tubbing segments for tunnelling and deep mining constructions.
