By dredging we maintain, deepen or widen waterways. Jan De Nul Group has a fleet of trailing suction hopper dredgers, cutter suction dredgers, split hopper barges and backhoe dredgers. Depending on the nature of the soil to be dredged and the required draught, the best suited vessels are deployed. When dredging contaminated sediments, We can also take on their treatment.

Jan De Nul Group creates new beaches and develops new land for residential, recreational or industrial use. Dredging vessels spray the soil ashore using the rainbowing technique or pump it to the shore through a pipeline. We can also use dump trucks for filling up the site.

Our seabed is filled with dunes, troughs and other irregularities. That is why interventions are necessary when installing offshore structures. To ensure a stable base, the seabed is first ‘prepared’. We do this by dredging dunes, levelling the surface and, if needed, placing a first layer of gravel. Pipelines and cables are preferably installed under the seabed. For this, we excavate special trenches that start at sea, may pass across the foreshore and end on land.
