Cofra B.V. is, just as it’s sister company Geotechnics B.V., part of the Boskalis Cofra Holding, which is part of the internationally operating dredging company Royal Boskalis Westminster. Geotechnics is the production and trading company, with MebraDrain, a prefabricated vertical wick drain, as its most important product.

The company’s priority is clearly on ground improvement solutions. Cofra is European market leader when it comes to the installation of vertical drainage and is continuously working on the development of new ground improvement techniques.

The daily management is in the hands of Mr. Hans van Eijk (director) and Mr. Ton van Veen (controller). In addition to the head office in Amsterdam, Cofra has offices in London, Stockholm, Singapore and Bratislava. Even in these tough times, prospects remain excellent. Besides the outlook on large projects, Cofra is working hard on new developments. Additionally, the synergy with Boskalis offers a lot of advantages.
