History

Today, the company has a strong position primarily thanks to its vision and courage. Courage of the founder, Jan De Nul, who grew from being a small contractor into an expanding dredging company. Also the courage of the next generation, which gives today the Group an impeccable worldwide reputation.

Jan De Nul started as a contractor of civil works. Anticipating the market opportunities which arose, the family De Nul took on its first dredging work in 1951. Soon after that, the first international dredging project was secured. The rest is history: over the ensuing years, Jan De Nul Group developed into a world leader in the dredging industry.

The Group would never have attained that position if it had not had the courage and vision to continue to invest in new equipment, a new dredging fleet, new employees and also new activities. In 1996, Envisan joined the Group as a subsidiary, having been established in 1992 and specializing in soil remediation and groundwater redevelopment. Together with the dredging and civil activities, it turned Jan De Nul Group into an all-round company. In brief, Jan De Nul Group is a company which is ready for the future.
