POLYVOID - THE REACTIVE SOIL AND THERMALLY EFFICIENT SUSPENDED SLAB SOLUTION

Welcome to PolyVoid

PolyVoid is Australia’s first fully compressible EPS (expanded polystyrene) void former for concrete suspended residential ground slabs.

The PolyVoid is uniquely designed as formwork in conjunction with a fully suspended slab placed on-ground to offer significant protection against the effects of varying soil characteristics such as settlement and heave.

This means that you will have the most structurally sound foundation for your investment, and the Polyvoid slab allows heave and shrinkage of the underlying soil without significant damage to your slab.

As an additional benefit, the R-Value of your Polyvoid slab is significantly more than that of a traditional waffle slab – saving you on your future energy bills.

This website has been designed specifically to cater for all relevant parties throughout the building process. From the Geotechnical Engineer to Structure Engineer and the Builder to the Home Owner, we have your answer covered. If you would like to know more than the site provides, please follow the link below and fill in the form. We will be happy to help.

The Polyvoid design manual and good building practice notes are available upon request.
