Sustainable alternatives to polystyrene void forming systems have been available in Australia for years. So why are most slabs still built the same way they were 20 years ago?

The barrier isn't technology or cost. It's awareness. And the cost of that gap shows up downstream: construction sites are the largest single source of the polystyrene that ends up in waterways like the Yarra.

Sustainable Foundations Group is an independent industry coalition. We don't sell products. We help builders, engineers and policymakers get the full picture before they decide.

What would you like to know about sustainable foundation systems?

Sustainable Foundations Group is built around one idea: give construction professionals the full picture and they'll make good decisions.

We don't tell anyone what to specify. We gather the evidence on foundation materials, check it, and share it clearly.

There’s a hidden source of construction waste beneath many concrete slabs.

Most people never see what sits underneath a concrete slab.

But during slab preparation, some foundation materials can break apart and create waste across construction sites.

This loose debris needs to be cleaned up and disposed of, adding to landfill and increasing work for builders.

It can also create safety hazards on site and lead to waste management issues that may attract attention from local councils or environmental regulators.

Since 2010, Cupolex has been supplying void-forming systems across Australia.

Cupolex modules are made from 100% recycled plastic and remain durable during installation, helping builders maintain cleaner construction sites.

Made in Australia, supporting more sustainable building practices.

Clean construction sites are safer construction sites.

onstruction sites can quickly become cluttered with loose materials and waste during installation.

Keeping the site organised helps improve efficiency, reduce cleanup work and improve safety for workers on site.

It can also help reduce the risk of waste issues that may attract attention from local councils or environmental regulators.

Since 2010, Cupolex has been supplying void-forming systems across Australia.

Cupolex modules are made from 100% recycled plastic and remain durable during installation, helping builders keep slab preparation areas clean, organised and safer.

Made in Australia, the system provides a practical and reliable approach to building foundations.

Why are domes one of the strongest shapes in engineering?

For thousands of years, builders have used arches and domes to create strong and durable structures.

You can see these shapes in historic buildings, bridges and aqueducts throughout Italy and across Europe.

The reason is simple — dome shapes distribute loads efficiently and transfer forces evenly through the structure.

This same principle is used in modern construction systems.

Since 2010, Cupolex has been supplying void-forming systems across Australia.

Cupolex modules use a dome-shaped design to create voids beneath concrete slabs while supporting structural performance.

Manufactured from 100% recycled plastic and made in Australia, the system combines proven engineering principles with modern sustainable materials.

What actually sits under a concrete slab?

Most people see the finished slab, but the systems underneath it are just as important.

In reactive soil conditions, the ground can expand and contract depending on moisture levels.

To manage this movement, engineers often design foundations with void space beneath the slab.

Void-forming systems create that space so soil movement occurs without pushing against the concrete.

Since 2010, Cupolex has been supplying void-forming systems across Australia.

Cupolex modules are made from 100% recycled plastic and create dome-shaped voids beneath concrete slabs.

Made in Australia, they provide a durable and sustainable foundation solution.

Why Australian manufacturing matters in construction.

Reliable supply is critical in the building industry.

When materials are manufactured locally, builders can benefit from better availability, shorter transport distances and stronger supply chains.

Since 2010, Cupolex has been supplying void-forming systems across Australia.

The system is made in Australia, supporting local manufacturing while providing a durable alternative to traditional foam waffle pods.

It’s a smarter and more sustainable way to build foundations.

Foam waffle pods vs recycled plastic void formers.

Many concrete slabs in Australia are built using EPS waffle pods.

While they are commonly used, foam pods can break during installation and create waste across construction sites.

Cupolex offers a different approach.

Since 2010, Cupolex has supplied dome-shaped void former modules made from recycled plastic.

The durable modules help create controlled voids beneath slabs while reducing site waste compared to traditional foam systems.

It’s a cleaner and more sustainable way to build foundations.
