How to build a Polyvoid Slab

At Katana Foundations we have this little ripper – we construct these slabs daily in Melbourne.

It seems like a secret – we do tell folk about it, but we are working on making them even better. Polyvoid is a Suspended Ground Floor slab that allows expansive soils to do what they like under the slab without cracking, damage or differential settlement to your home – peace of mind.

Take a look at our time lapse, taken last Friday, note the piles sticking out the ground at the start and how the crushable voids come together to form the slab.
