Enviroclad Expanded Polystyrene voids are a cost effective, light weight structural fill solution.  They decrease the volume of concrete helping to reduce the overall weight whilst increasing the structure strength. Voids can be used as a temporary application or as part of a formwork system.  Voids are typically used in a variety of applications from roadways, underpasses, shopping centres, bridges, tank cradles, foundation and embankments.  At Enviroclad we manufacture voids to suit your project.
