Concrete & Marine Void Blockouts

Polystyrene Concrete Voids

Polystyrene Products makes blocks for use in the engineering, building and construction industry as void formers in concrete, and bridge void beams for block outs used in bridge construction. We cut them to any size and shape, including complex profiles.

The pieces are delivered to the jobsite pre-cut and ready to use. After the concrete cures, the EPS can then be removed or left in situ if required.
