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.
