Evo-Crete® vs concrete: A crack is not a crack

Evo-Crete+AC+Blocks+-+Complete+Mounting+KitThe technology of Evo-Crete® is defying all common concrete conceptions, including the generally accepted notion that a crack spells the end for the usefulness of a concrete slab.

Evo-Crete is ultra-lightweight fibre reinforced concrete that is three times lighter than standard concrete. It is a lightweight alternative with superior strength-to-weight properties over standard heavy pre-cast concrete products.

One key ingredient to Evo-Crete’s success is the proprietary blend of Evo-Fibre polyolefin fibre reinforcing. When added to a concrete mix the unique blend of Evo-Fibre provides improved abrasion resistance, as well as increased flexural and compressive strength.

As Evo-Fibre is distributed evenly throughout the concrete mix, the three-dimensional reinforcement matrix ensures maximum durability and product stability. Evo-Fibre helps prevent cracking in the first instance (pre-crack reinforcement) and offers excellent post-crack reinforcement.


Pizza Bases roll out nationally

Since the launch of Polyslab Pizza Bases, these hot water system support bases are becoming rapidly popular in the plumbing sector.

The popularity of the Pizza Base lies in its advanced design features. Plumbers have embraced the product as it is high quality, easy to use, one size fits all, Australian made and recycled. The rapid market uptake is reflective of the product’s simplicity, durability, and design features that have created a functional product with real cost and inventory benefits.

The standout feature of the bases is the innovative ‘snap-away’ design so installers simply snap away the outer ring for the required size reducing inventory requirements. The Pizza Base meets ASNZ3500 installation standard in terms of airflow and support ratios.

Anyone can now get their hands on a Pizza Base at their local plumbing supplies branch, no matter where they are based right across Australia.

Polyslab® Pizza Bases enter hot water system market

Product+-+Polyslab+Pizza+BaseThe Pizza Base is a slimline hot water system (HWS) support base that is already finding an important place in the HWS market.

All leading plumbing supplies retailers and wholesalers are currently stocking the one-size-fits-all Pizza Bases. The HWS support is available in 650, 520 and 410mm diameters all in one product. Thanks to their innovative ‘snap-away’ design, plumbers can snap away the outer rings of the base for the smaller sizes.

Pizza Bases are designed and engineered to meet the hot water system installation standard ASNZ3500, specifically the airflow and support ratio and corrosion avoidance measures.

Evolve Composites’ Alyson Dunlop said that by sliding a Polyslab Pizza Base between the hot water system base and the supporting surface, legislation needs are easily met.

“Supporting surfaces can include concrete plinths or pathways, and they are great for safe-tray applications,” added Alyson. “They are suitable for indoor or outdoor use.”

Pizza Bases are 12mm thick and made from a highly durable UV stabilised co-polymer material.

“They are lightweight yet carry an impressive 1000 kilogram load rating. This base is tough enough to carry the weight of any hot water system on the market,” said Alyson.

All Polyslab bases are Australian made from 100 per cent recycled materials, meaning that the snap away excess material can be re-used and recycled.

“What our distributors are enjoying about pizza bases are the significant economic advantage that they provide by immediately reducing inventory and associated costs by 66 per cent,” explained Alyson.

“Retailers and plumbers only need to hold one product to match any hot water system sizing.”
