Your Keystone to Perfection.

Roundabout and at the heart.

Advanced technologies and adequate experience are required for lining machine-driven tunnels under inner cities, mountains and rivers, to ensure the absolute safety and long life of the finished tunnel. Herrenknecht tunnel boring machines install hundreds of segments daily into large and small tunnel tubes. Each segment has to be ready at exactly the right moment and installed in a perfect fit. Behind all this is a complex process, which we always keep in focus. Alongside our precision moulds, we are right at the heart of the entire tunnelling process to ensure that each segment rim precisely fits the next.

Teamwork Tunnelling.

As a wholly-owned subsidiary of Herrenknecht AG, we specialize in the production of high-tech equipment for the manufacture of precision lining segments. We handle projects hand in hand with the Herrenknecht Group, accessing more than 30 years of experience. In close cooperation with our partners and customers, we continue to develop existing technologies. Proven methods and new ideas, backed by a highly motivated team are the formula for reliable tunnel lining with Herrenknecht Formwork.
