Our Civil & Ports
Division

Infrastructure below the waterline


With over 60 years of experience, our Civil & Ports division delivers reliable underwater solutions for civil infrastructure and port environments. From large-scale construction projects to daily maintenance works, we combine practical expertise with a strong focus on quality and safety.

Our activities include, but are not limited to, underwater concreting, tunneling support and sluice maintenance. Having placed more than 6 million m³ of underwater concrete, DCN is recognized as a leading specialist in this field. We have contributed to major projects such as the Markthal, the Queensferry Crossing and the expansion of the Suez Canal.

In addition to new-build works, we support the inspection, maintenance and repair of sluices, intakes, sewage systems and quay walls. With a fleet of fully equipped diving units, DCN can mobilize rapidly and respond within hours when needed.
