Coastal
protection

With its roots in the Netherlands, Boskalis has over 100 years’ experience in coastal protection. Today we design, construct and maintain hard sea defenses such as dikes, dams and flood barriers. In addition, we offer environmentally sensitive soft sea defense solutions through the creation of wave-reducing islands, beach replenishment or the construction of a so-called sand motor to spread sand along the coast from a central replenishment location using natural forces.

Shoring up coastlines around the world

We put our vast experience and expertise to good use protecting coastlines and boosting flood defenses around the world. Ensuring safety while maintaining a well-balanced ecosystem are key. As part of our integrated solutions, we can provide both economic and environmental assessments to ensure the ideal delivery of your coastal protection project.

Climate change, sea level rise and extreme weather are increasing the need for coastal protection around the world.

Cleanup sediment treatment, Fox river

As a result of industrialization the riverbed of the Fox River (Wisconsin, USA) had become contaminated with PCBs (polychlorinated biphenyls). Joining together a number of large paper mills based on the banks of the river have established the Fox River Cleanup Group to handle the remediation project. The site is on the federal Superfund program’s National Priorities List.

Construction motorway, A4 Delft-Schiedam

Boskalis Nederland was involved in the construction of the A4 motorway from Delft to Schiedam. The client is Rijkswaterstaat. After 40 years, the construction of this final section will bring to an end the public debate about whether this new road was needed.

Channel expansion, Suez

The Suez Canal is one of the world’s main shipping links and thus of major importance to world trade. The canal extends from Suez on the Red Sea to Port Said on the Mediterranean. Egypt’s Suez Canal Authority awarded the contract to double the canal’s capacity to a consortium, which was aptly named the Challenge Consortium by the Chairman of the Suez Canal Authority, Admiral Mohab Mamish.
