Ruhrort Harbor Expansion
Thanks to increasingly large orders from heavy industry, by 1910 at the latest, HOCHTIEF was concentrating on orders in the Ruhr district. The improved technical options resulting from the invention of reinforced concrete played a major role here. The image shows a grab dredger, which is sinking the foundations for the expansion of Ruhrort harbor. During the years to come, HOCHTIEF also completed many hydraulic engineering projects in the region, for example lock I in Meiderich.
