After the war, the years of construction, groundwork was started. Digging construction pits and constructing sewers was easy to combine with the transport company.
In the sixties things changed. The contract work was stopped. Transport shifted to steel, cranes and machines. It turned out to be an impulse for further growth. In the 1970s it was expanded with crane rental, mounting of steel structures and the rental of internal transport equipment.
In 2009 the family business of Elk Transport from Haarlem was taken over. In 2010, all activities of J. Verbeek Transport and Kraanverhuur B.V. added from Hoofddorp. In January 2013, the crane activities of De Koker from Hoofddorp were taken over.
In August 2014, the activities of Kieboom Transport Systems in Beverwijk were taken over. The Van Santen Group is now a company with more than 90 skilled employees.
