| Background knowledge on the subject of tunneling Tunneling has a long history. It makes many demands on man and machine, so it is a great challenge for all involved. At the same time, tunneling offers many solutions to problems, which could hardly be more varied. You will find more on this fascinating and complex subject here. | 
| Full-face tunnel boring The prevailing local geology has a decisive influence on the construction of individual full-face tunnel boring machines. A fundamental distinction is made between rock (hard rock) and earth (soft soil), although, naturally, there are also solutions which combine both. | 
| Open tunnel boring machines Driving in stable rock
This type of boring machine is suitable for driving in stable rock and is used for the excavation of traffic tunnels (road and rail), supply tunnels (water, gas and electricity), pressure water utility tunnels for hydroelectric plants, tunnels for cable cars high in the mountains, tunnels for geological investigations and other special applications.
The main elements in the construction of the open tunnel boring machine are the cutter head with its associated drive housing, the support construction (the so-called gripper) and the advance mechanism.

| Research & Development The contribution of research & development to the overall success of the company cannot be underestimated. A good example of our R&D efforts is the undercutting technology, which was successfully applied in the field. For this new tunneling technology WIRTH was awarded the innovation prize in 2005 | 
| Selective face tunneling Selective face systems are versatile machines which are not only used in tunneling, but have also established themselves in the mining world. Here, Roadheaders, Continuous Miners and Mobile Tunnel Miners are all used. | 
| Trenchless infrastructure laying Building conditions or environmental considerations often prevent overground connection by the owner. In these cases, technical systems for trenchless laying must be used. | |
