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.

Port construction,
Khalifa port

The Khalifa Port and Industrial Zone (KPIZ), one of the world’s largest greenfield development projects, is part of Abu Dhabi’s major diversification plan to develop various sectors such as property, tourism, infrastructure and others. Abu Dhabi’s main existing port, Mina Zayed, is hemmed in by Abu Dhabi city, limiting its accessibility and the possibility for expansion.

Maintenance dredging, Berbice River

One of Guyana’s major export products is bauxite, which originates from the Aroaima, Kwakwani and Ituni regions around the Demerara and Berbice rivers in north-eastern Guyana. Guyana annually exports approximately 2.2 million tons of bauxite from it’s mines along the Berbice River. Boskalis International has long been associated with the mining industry in Guyana. In 1990 a long-term overburden removal project for the Aroaima mine was begun in Guyana involving the dredging and disposal of a sand and clay layer of 30-45 meters thickness.

Coastal protection, St. Petersburg

St. Petersburg is a UNESCO World Heritage City, but its location along the River Neva means that it has been threatened by over 300 floods since its founding by Peter the Great in 1703. The completion of the new 25 km long storm-surge barrier across the Gulf of Finland ensures that the city will no longer be vulnerable to high tides and devastating floods. As a result of the new Flood Protection Barrier, however, the old winding access channel had to be replaced with a new, straighter, more easily navigable channel.

Cleanup, Zellingwijk area

The Zellingwijk quarter of the village of Gouderak was built in the middle of the last century. In the early 1980s it became clear that the soil underneath this residential area was heavily contaminated as a result of the dumping of waste - mainly mineral oils and pesticides. The homes built on the site were subsequently demolished in the mid-1980s. Pending definitive remediation work, a layer of concrete / asphalt was applied to seal the site.

Overview activities, Bahrain

The Kingdom of Bahrain is an island located in the Gulf, east of Saudi Arabia and north of Qatar and connected with its neighbour Saudi Arabia since the year 1980 with a 25 km long causeway. The archipelago consists of some 30 islands with a total of 160 km of shoreline and has a population of 800,000. Whereas the surface of Bahrain in the year 1960 was around 650 km2, the last decennia have seen a steady increase in the surface till a respectable figure of 740 km2 in 2007. This increase has been achieved by a various number of small and mayor reclamation projects.
