Within the Lange Haven Plus project, the canal in Schiedam is being brought back in good condition. At the same time, the work is being used to give the revised quays a new layout.
17,000 m of screw piles will be placed inside and behind the quay walls. These walls do not need to be completely overhauled; after the screw piles have been placed, the load-bearing function of the quay walls will disappear. Concrete precast elements are put onto the piles to distribute the pressure from surface loading. The advantage of this approach is that the existing quays can be maintained.
