When North Blacktown Public School needed a driveway and car parking bays that could handle daily school-grounds traffic without adding to local stormwater pressure, permeable concrete was the obvious answer — and Wizcrete was contracted to install it.
The project covered 650m² of permeable concrete across the driveway and car parking bays, delivered in conjunction with Australian Permeable Concrete, the number one permeable contractor and supplier in Australia.

The Partnership
Permeable concrete isn't standard concrete. Getting it right takes specialist knowledge at every stage — from mix design to site preparation to finishing.
Working alongside Australian Permeable Concrete gave the school the best of both worlds: Australia's leading permeable supplier, paired with Wizcrete's experienced installation team.
Getting the Site Right First
Permeable concrete only performs if the site underneath is prepared correctly. Unlike a standard slab, permeable surfaces rely on water passing straight through into the sub-base and beyond.
That means the preparation has to support:
- Correct permeability through the full profile
- Structural capacity for vehicle traffic
- Reliable long-term drainage without clogging or ponding
Wizcrete prepared the site correctly before any concrete was placed — the unglamorous groundwork that determines whether the finished surface still works in ten years' time.

Why Permeable Concrete?
Five reasons made it the right solution for this school:
80% Less Runoff
Water drains through the surface, reducing stormwater load on council infrastructure.
Council Compliant
Meets WSUD requirements for new driveways, pathways and car parks.
Eco-Friendly
Filters pollutants and recharges groundwater naturally.
Reduces Heat
Lighter surface reflects heat, unlike dark asphalt.
Durable
Handles vehicle traffic and lasts for years without cracking or sinking.
The Installation
This is where permeable concrete diverges from standard concreting — and why specialist concreters were essential.
Permeable concrete cannot be pumped. Traditional concrete is typically pumped to the site for speed and convenience. Permeable concrete has to be placed directly, which changes the whole logistical approach and requires a trained crew on the ground.
Our specialist concreters carried out the work, screeding and finishing with our lightweight pole-mounted mechanical trowel — the right tool for achieving a consistent finish across a large permeable surface without overworking the material, which would compromise its permeability.
Permeable concrete being placed directly on site — it cannot be pumped
The Result
650m² of properly installed, correctly prepared permeable concrete — a greener, cooler, council-compliant surface built to serve the school community for years.
Driveway and car parking bays installed
Less stormwater runoff
Council compliant by design
Direct-placed, no pumping possible
