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.

Regaining momentum after the First World War

The end of the First World War did not result in things returning to normal right away for DEME’s founders. The loss of their fleet had a severe impact, and much of the international activity that had defined the pre-war years was disrupted.

However, rather than retreat, the founders adapted to the new realities of the post war period. Drawing on hard-earned experience, trusted partnerships, and the strength of their people, they gradually restarted operations closer to home. In Belgium, dredging and port works resumed, which included maintenance on the Scheldt River and in the Port of Antwerp, which were essential efforts to restore maritime access in a recovering post-war economy.

These early post-war years marked a quiet but decisive turning point for DEME. Despite recording significant losses, the founders never gave up and instead laid the foundations for a renewed phase of activity.

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.
