Underground construction projects: Tunnels are built not only for people and traffic, but these underground pathways are also constructed for the transport of energy, water and other media.

To create underground structures, the structure and parameters of the subsoil as well as the hydro-geological conditions have to be explored first and then evaluated by a qualified specialist. This is the only way to select suitable construction methods that can guarantee safety during construction and for the subsequent use of the structure. The structures and the construction process are planned in such a way that the completed tunnel can withstand the pressures of soil, rock and water.
