Upstream repairs in the tidal fall zone for a storage reservoir
Underwater work, although less than three metres deep, enabled Cegerco professionals to once again show their creativity. Faced with a high-risk problem that required divers, Cegerco chose a far safer strategy... “dry” work!

Our innovative approach involved the use of a caisson that could withstand hydraulic pressures and follow the irregular surfaces of the varying profiles of structures. Moving in water was made possible by the use of ballast tanks that offset the physical and hydraulic centres of gravity of the assembly.
