Ballast Nedam Grond en Wegen Grondstoffen BV

The existence of the Amsterdamsche Ballast Maatschappij can be attributed to the North Sea canal [Noordzeekanaal]. Its original operations back in 1877 were simplicity itself: empty merchant ships going to sea obtained dune sand as ballast. In later years, the company also applied itself to dredging.

H.F. Boersma set up in business as a contractor in Den Haag from 1899 onwards. In 1917, Boersma founded the company Nederlandse Aannemingsmaatschappij N.V. The Ballast Nedam Group came into being through the amalgamation of the two companies in 1969.

• 1989: Amsterdamse Ballast, Nedam and Broekhoven merged to form Ballast Nedam.
• 2001: Ballast Nedam, Dredging Division, and Ham merge to form Ballast Ham Dredging.
• 2002 Ballast Ham Dredging owned by Dragados Spain and sold to BAM NBM
• 2003: Van Oord ACZ en Ballast Ham Dredging merge to form Van Oord NV

Only the dredging division was taken over by Van Oord. Ballast Nedam, which now offers a wide range of products and services related to construction, still exists (http://www.ballast-nedam.com).
