Project

We also have a complete range of sinking equipment, including multiple overpressure systems for caisson sinking, habitat activities, overpressure work on tunnel drilling systems, etc. Thanks to our joint ventures with partner companies, we also have the piledriving and excavation equipment for circular cofferdams.

We also offer further possibilities both independently and by means of our joint ventures. These include complete contracting and execution of tunnel unit sinking activities, caisson sinking activities, and the construction and dry delivery of circular cofferdams with underwater concrete. You can also turn to us for the complete contracting and execution of the maintenance and/or repairs on sluice systems, dams, earth dams, etc.
