Part of the Botlek port in the port area of Rotterdam needed to be filled up to reclaim 5 hectares for the Botlek Tank Terminal site.
A total of 500,000 m3 of sand was brought in to fill up the terrain. The filling process was carried out layer by layer with a sprinkling nozzle attached to the trailing suction hopper dredger.
Soil protection was installed in front of the quay walls (415 m). In order to comply with the soil compaction standards, over 450 km of vertical drainage took place.
