Secondary materials: granulates

Concrete and brick rubble from construction and demolition projects, old foundation materials from road reconstruction work and asphalt from road buildings projects are crushed and processed at our site in Westervoort (NL).

The crushing plant in Westervoort serves the Arnhem, Nijmegen, Ede, Apeldoorn, North-Brabant and North-Limburg regions. 

The following products are manufactured: mixed granulate, asphalt granulate and concrete granulate for the road building, asphalting and concrete industry. Our approach guarantees optimum quality. The crushing process and delivery and distribution are subject to constant monitoring in respect of health and safety at work, environmental requirements and quality assurance.

On stock
Putman maintains a considerable storage capacity for uncrushed rubble and crushed products at a wide range of granular sizes. As a consequence, Putman is able to supply from stock and transports the products efficiently by road or water, using its own transport equipment. Putman has loading and unloading facilities and as a consequence is ideally capable of providing transport by ship.
