Track ballast material is subject to stringent requirements. It must be highly resistant to dynamic shattering. The material must not only be hard and durable, but also angular so that it interlinks well and provides lateral resistance. Railway construction is a project-related market. As a consequence, logistics is an extremely important factor. Projects require flexibility in terms of delivery with regard to both size and method of transport. Given that our terminal in Amsterdam is located close to deep water, directly alongside a motorway and with a railway link, we have the option of delivering by ship, lorry and railway wagon.
