Repairing civil engineering structures View the presentation video Our pluridisciplinary technique generally avoids sub-contracting to facilitate works coordination. As early as site preparation stage, Nouvetra takes environmental constraints into account and respect for local residents in the context of its QSE approach; it keeps a watchful eye on the protection of fauna and flora, water diversions and on reducing noise and air pollution levels. Mastered techniques : retaining elements, rigid framed bridges and rail bridges ; structure repairs: hydro-demolition, repointing, resurfacing, shotcretes, strain carriers, self drilling bars, injection of bonding materials and re-activation ; jacking of structures, changing bearing devices ; pavement joints and impermeability ; construction of new structures ; treatment of reinforcement bars (anodes) ; strengthening with carbon.
