Tunnel and Gallery Construction

Tunnels and galleries are important elements of modern infrastructure. They are not only important components of road and transport networks, but they also play an important role for example, in the supply of drinking water and in the de-watering of mined areas, as well as in ventilation and for transport purposes in mining.

We are experts in the assessment, planning and monitoring of rehabilitation work on existing tunnels as well as in the exploration, project planning and engineering-geological and geotechnical monitoring of the construction of new tunnels or tunnel connections. Benefit from our specialist knowledge and the wealth of experience of our experts. We are your competent and reliable partner for your projects.
