Tunnels are NOUVETRA's core business.
Rail, motorway and river tunnels: NOUVETRA operates throughout France, mainly for renovation projects. NOUVETRA's mastery of innovative and specific techniques, its trained personnel and its adapted equipment enable it to work in these confined environments.
NOUVETRA uses road, road-rail, work train or barge resources to intervene, whether on an operated network, under beaconing, with partial or total interruption of traffic, day or night.
Thanks to its mastery of all the techniques involved in renovating tunnels and underground structures, and with the support of a large, experienced management team, NOUVETRA is able to manage large-scale projects involving the most complex technical aspects.
