GALLERIES

Tunnels of small section for hydraulic works, industrial facilities, approach to underground stations, connection between double-tube tunnels, emergency galleries in large rail or road tunnels, ventilation systems, etc...

This kind of work requires the use of specific machinery, especially for removing debris, because its small section makes maneuvering of the machines difficult.

Nortúnel has wide experience in the use of LHD machines (loaders - conveyor) and ITC machines.
