Our history

A road full of memories

From sand supplier to an international construction and development company

Our history dates back to 1877. Ballast Nedam started under the name 'Ballast’. First, as a sand supplier providing empty merchant ships that went to sea with a sand ballast. Thanks to our first project 'The Afsluitdijk', constructed in 1927, the ‘Nederlandse Aannemers Maatschappij’ (Nedam) became well known as a construction company. In 1969 the companies Ballast and Nedam merged into Ballast Nedam. In 2015, we became part of Rönesans Holding, our parent company. Together, and with the dedication of our skilled people, we are building towards a sustainable future.
