DSI Construction announces Joint Venture with Interspan

  • Strategic partnership for strengthening market presence in Europe 

  • Successful start with first major contracts

DSI is pleased to announce the establishment of the Joint Venture Holding company DYWIDAG Interspan Holdings B.V.. Headquartered in Zaltbommel, Netherlands, it consists of the partners DSI and Interspan.

The new JV will support the DSI Group on core international markets with its know-how in civil and ground engineering and will create synergies for both companies. The technical expertise and the global experience of DSI, combined with the agility and engineering expertise of Interspan, will permit an intensification of market cultivation and an expansion of their scope of services.

The group has appointed Mr. Philipp Demelt as the new General Manager of DYWIDAG-Interspan. We congratulate him on his new position and wish him the best of success. The JV will initially develop regions within Europe, with a targeted future growth in global markets.



In the short time since its establishment, DYWIDAG-INTERSPAN has already successfully acquired several major projects in Belgium and the Netherlands. Within the first 5 months, more than 30.000 sq m of floor slabs have been post-tensioned using DSI’s bonded and unbonded systems.

James Laws, owner and director of Interspan, comments: “DSI is a strong global partner with an extraordinary history and an excellent reputation. The joint enterprise strategically strengthens our market position in important regions of growth. It also represents a major step in our medium to long term growth strategy. We would like to warmly welcome all employees of DYWIDAG-INTERSPAN.

Hans Wlodkowski, RCEO for DSI’s construction business in the EMEA region, comments: “Partnering with Interspan in the European Economic Area will allow DSI to transfer its experience in post-tensioning to the building industry. Thanks to this strong partner with huge competences in the design and execution of floor slabs, we can now target new major building projects. I am convinced that the Joint Venture will provide best services and products to our customers.”
