Coastal defense and
riverbank protection

Boskalis is a leading global player in the field of coastal defense and riverbank protection. We design, construct and maintain hard sea barriers, such as dikes, dams and flood barriers, and also soft sea defenses, such as beach and near-shore replenishment. In addition, we provide innovative solutions for forms of coastal protection based on the principles of building with nature such as the sand motors and the use of mangroves.

Ensuring safety and natural balance

Safety and a natural balance are the most important aspects of good coastal protection. Our vast experience and expertise enable us to assist you with the economic and environmental assessment of your coastal protection project. We have a proven track record and the drive to maintain a well-balanced ecosystem.


Our innovative and building with nature solutions

  • Sand motors use natural forces like tides, wind, currents and waves to spread sand along the coast from a central replenishment location.
  • The creation of a wave-reducing system. Examples are the combined approach of land reclamation and new mangrove forests to protect the North Java coastal area in Indonesia and a green wave reducing dike in The Netherlands. A willow forest, planted along the front of the dike, is expected to be able to absorb up to 80% of the waves’ force.

Cleanup, Westergasfabriek

The Westergasfabriek was built by the British firm Imperial Continental Gas Association (ICGA) in 1883, and was at the time the biggest coal-fired gas factory in Amsterdam. The project site, covering four hectares, housed coal storage yards, gasometers, purification plants, a water tower and office buildings, all designed by the famous Dutch architect Isaac Gosschalk. The municipal energy company used the site for storage into the early 1990s.

This major infrastructure project is carried out in advance of the planned expansion of the Bahrain port activities. This New Port project is planned at the Hidd side and via the Shaikh Khalifa Bin Salman Causeway direct connected with the existing Mina Sulman port and Saudi Arabia.

Land reclamation Check Lap Kok airport Hong Kong

In 1996 Hong Kong was a modern city-state with almost 6 million inhabitants where air traffic was a very important component for economic activity. The old airport Kai Tak, with a single runway, was no longer able to cope with the growing number of passengers and amount of freight.  The authorities decided to build a new, bigger airport at a new location in Hong Kong, a 350 hectares hilly island off the coast about 28 km west of the city center.
