In architecture more and more difficult 3D curved shapes are required in concrete. The huge number of woodworking specialists in the mould making is very capable but they also experience an elevated standard. Nedcam developed several techniques in the yacht building and composite industry used today for 3D moulds for concrete. This method is based on a machined shape in MDF or EPS (Styrofoam) covered with a rigid layer of synthetic material. In this way small moulds as well as huge moulds like a complete bridge can be made!

In case of large objects Nedcam focuses mainly on the complexity of the shape. Machinable materials are used that can stand the surface pressure of the concrete during pouring. In cooperation with the construction company a complete custom made moulding system need to be engineered around the shaped Nedcam material.

On small scale Nedcam produced several EPS inserts in moulds for concrete. Our customer Heijmans used the inserts to create faces at the end of walls and tree structure to turn pillars of a viaduct into trees. In cooperation with Ballast Nedam, Nedcam did a pilot project for the new Central Station in Arnhem. Some prefab GFRC (glass fibre reinforced concrete) panels were made that fit in the challenging design of architect UN-studio.

On large scale Nedcam machined the complete bottom of the Spencer Dock Bridge in Dublin. The design of Future Systems (London) was converted by Nedcam into a building system:
3D drawing of a falsework with plywood sheet material     mounted with high accuracy. To be built by the contractor.
3D drawing of the mould divided in machinable parts that fit     seamless on the falsework.
Production engineering for the EPS-blocks at Nedcam
An assembly plan with numbering system that will assure     simple stacking of the parts as logistically arranged in the right     order.
