In order to make Amsterdam accessible for the new generations of ships with even larger dimensions, the largest lock in the world will be built in IJmuiden located at the south of the 27-km long North Sea Canal, which connects Amsterdam with the sea. Dyckerhoff Basal, one of the largest suppliers of ready-mix concrete and cement in the Netherlands, is providing the concrete mix for the project. The largest lock in the world requires around 300,000 cu m of concrete.

For Dyckerhoff Basal, the most important criterion in selecting the concrete mixing plant was a rapid start of operation and the possibility of a rapid change of location in the future in order to be able to start concrete production at short notice for construction projects with limited time. In addition, a theoretical output capacity of up to 150 cu m/hr was an essential requirement for the mixing plant in order to reliably cover delivery peaks throughout the day.

Liebherr and Dyckerhoff Basal have selected the Mobilmix 3.5-C in container design with CSC approval for cost-effective and worldwide ship transport as the optimum solution under the given conditions. The Mobilmix 3.5-C is ideally suited for quick installation and relocation in temporary construction projects.
