The erection of free-standing technical buildings is sometimes not approved in agglomerations and environments governed by strict design regulations.

An underground station from Betonbau is the best choice in this case.

The station technology simply »vanishes« beneath the surface of the terrain, and the area can utilised further for its former purpose with practically no limitations. Access entrances and ventilation elements are adapted to suit local conditions, and the plant can even be planned to support traffic passing over it. Underground stations are utilised in the following areas:

  • Airports
  • Historic town centre
  • Inner-city sites
  • Escape and rescue areas


High requirements for competent solutions

  • Capacity to resist subsoil pressure
  • Sealing against surface and ground water
  • Reliably-functioning, natural transformer cooling
  • Station ventilation and aeration to limit condensation Stationsbe- und -entlüftung
