For more than 10 years, we offer our clients a substantial portfolio of technical solutions and services for tunnel projects of any diameter and for any segment thickness or geometry requested.

Herrenknecht Formwork Technology GmbH was founded in 2007 as a wholly owned subsidiary of Herrenknecht AG in Schwanau-Allmannsweier (southern Germany). As part of the Herrenknecht Group, we participate in 40 years of know-how and experience gained by the world market leader for mechanized tunnelling technology. We are thus part of a professional and future-oriented group with a worldwide network of competence and service. We have state-of-the-art manufacturing and assembly capacities in Maribor (Slovenia). Our 40 employees in the technical and commercial areas are experienced and highly qualified specialists and engineers.

The responsible staff in Project Management and After Sales are available to our customers as direct and personal contacts throughout the entire duration of the project. This ensures we always have the big picture in mind regarding all aspects of our customers' projects. Our management processes in the company are ISO 9001 tested and certified. To protect the environment, we invest in resource-saving production facilities and processes.

We bring our experience from more than 200 projects and over 5,000 precision moulds produced into a network of cooperation partners and representatives of the professional community. The regular Formwork Days we run have established themselves as a leading forum for formwork and tunnelling specialists around the world.
