At Ballast Nedam Specialistisch Grondverzet, we keep our feet firmly in the clay. Drawing on our broad expertise in earthworks, we quite literally lay the foundations for a wide range of construction and infrastructure projects. Our activities include the delivery of complete excavation pits up to 30 metres deep, complex foundation works, quay structures, coastal and riverbank works, and both wet and dry earthmoving operations. While most of our projects are carried out in the Netherlands, we also work internationally when required. We do so using our own people and our own equipment.
