Building on water, it’s our business!

About us

FlexBase BV is a company with more than 8 years of experience in designing and building floating and amphibious structures. The company was established as a result of the cooperation between Dura Vermeer, one of the leading building companies in The Netherlands, and Kingspan Unidek, the biggest EPS producer in Europe. Our main concept is a float made of EPS but other solutions such as concrete hulls, composite structures or other low cost floating solutions can be applied. Together with the customer the best fit to the requirements is determined, resulting in the optimum ratio between usage, design and cost.

Added value

In parallel to changes in the way governments think about water, creative minds are also considering how to rise to the challenge of balancing the contradictory needs of more space for construction and more space for water.
Versatile use of space is achieved by combining wet and dry functions. Issues related to water overflow, scarcity of space and the desire to live in greater ecological harmony with our environment have all stimulated the development of floating forms of construction.
The ability to simultaneously satisfy multiple interests will ultimately lead to increased added value.


Our mission is to provide a comprehensive design consultancy and manufacturing service for floating and amphibious projects based on many years of experience with “Building on Water”.
Together with local partners we develop and design floating structures which will be manufactured with local companies under supervision of FlexBase.

The Dutch Foundation for Experimental Public Housing (Stichting Experimenten Volkshuisvesting or SEV) and the Dutch Living with Water Foundation (Stichting Leven met Water) have indicated that policies of the municipalities, water boards and provinces are the main factors in shaping a legislative framework.
The primary assumption is that the floating structure must satisfy Dutch Building Regulations (Bouwbesluit). Furthermore, the associated risks may not differ from those of land-based construction. For this reason, we have initiated together with the NEN Institute, a process to setup the National guide (NTA8111) for floating objects. This procedure has established properties such as buoyancy, stability and durability.
