Discover 150 years of DEME!

In 2026, DEME celebrates 150 years of marine and environmental engineering. From our early roots in 1876, we have grown from our origins in dredging and marine works into a leading, diversified group - shaped by expertise, innovation, resilience and a constant drive to push boundaries. 

Throughout this anniversary year, we’ll take you on a journey through our history, sharing stories and moments that show how challenges were approached, solutions were developed and ambitions kept moving forward. Across our channels and on this dedicated anniversary website, you can discover the people, projects and breakthroughs that made DEME what it is today. This website will be updated weekly with new stories. Throughout the year, we will use #DEME150 to share and connect these stories. 

As we reflect on 150 years, we continue to look ahead with the same spirit that defines us: We Care. We Dare. We Deliver.

1896

Reshaping Antwerp’s riverfront

At the end of the 19th century, improving access to the Scheldt was essential for the growth of the Port of Antwerp. In 1896, this resulted in a large-scale project to renew and reinforce the riverbanks.

To the south, new quays stretching nearly two kilometers were constructed. This was a unique partnership, bringing together government bodies, engineers, and expert contractors for an ambitious undertaking. It ranked among the boldest quay wall projects of the era, pushing all those who worked on it to their limits.

Hendrik Willem Ackermans and Nicolaas van Haaren were closely involved throughout the project, contributing their dredging and hydraulic engineering expertise. The works progressed under challenging conditions, from difficult subsoil to strong tidal forces and unpredictable weather.

Suction dredgers such as Schelde II supported both the construction and stabilization of the new quay walls.

In August 1903, the new southern quays were inaugurated and became a key access route to the growing Petroleum Zuid industrial area, a new lifeline for the port, built on years of craftsmanship, perseverance, and technical ingenuity. In the years that followed, the new quay area continued to grow and change, keeping pace with the rhythm of a port in full expansion.

With 150 years of history, there are countless moments to tell. In this anniversary year, we share a non-exhaustive selection of stories that illustrate how DEME became the company it is today. These stories are drawn from a variety of historical sources, including books by authors such as Dirk Podevijn and Mon Vanderosteyne, company publications and the input of colleagues across the organization. As this website looks back on 150 years of heritage, it features archival material from different eras. Safety standards and working practices have evolved significantly over time and should be understood in their historical context.
