Tunnels

Tunnels represent the historical activity of NOUVETRA.

Railway, road, or waterway tunnels: NOUVETRA operates throughout the country, primarily for renovation work. Mastery of innovative and specific techniques, trained personnel, and suitable equipment enable NOUVETRA to work in these confined environments.

Whether operating on active networks, under traffic signs, with partial or total traffic interruptions, day or night, NOUVETRA intervenes using road equipment, rail-road vehicles, work trains, or barges.

By mastering all techniques for renovating tunnels and underground structures, and with the support of a large and experienced management team, NOUVETRA is capable of managing large-scale projects involving the most complex technical requirements.
