Steel fibres have come a long way in a few decades – Helix Steel don’t make fibre, they make micro-rebar. With the price of steel and associated fixing costs going up, it makes sense that if we can replace processed reinforcing with micro rebar, we can make the Polyvoid Slab the simplest slab in the market. With app technology being proven at the batch plant and additional checks on site, all that is required is good finishing of the exposed areas of the concrete slab.
While simplification is always a win for everyone, an additional advantage is elimination of shrinkage cracking – reducing the concern for builders having to deal with this issue with the home owner.
Helix Steel are finalising the design and we look forward to undertaking this trial with our customers.
