The increasing demand of mankind for a higher quality of life and greater mobility requires that the supply lines be extended, in particular in the conurbations. With its high-tech products and methods in mechanical tunnelling Herrenknecht AG offers a key technology for creation of new environmentally friendly methods of mobility as economically and efficiently as possible. This is realised by the construction and linking of efficient underground pipe and tunnel networks. This also applies to the effective management of scarce resources such as water or waste water disposal. Innovations are introduced not only in the large machine sector (road, rail and underground railway tunnel construction). The field of micromachines with diameters of 0.2 to 4 m is also characterised by continuous innovations.
