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.

What is a void former?

When building on reactive soils, the ground beneath a slab can move depending on moisture conditions.

If that movement pushes against the concrete, it can cause cracking.

A void former creates space under the slab, so the ground can move without damaging the structure.

Cupolex uses dome-shaped modules made from recycled plastic to create that space, which helps build stronger and more reliable foundations.

What is actually underneath a concrete slab?

Most people never see it — and it plays a huge role in how a building performs over time.

From managing soil movement to reducing waste on site, foundation systems are more important than ever.

Have you ever thought about what lies beneath your feet? Stay tuned for more insights on how Cupolex works and where it's being used across Australia! Don’t miss out on our upcoming posts!

Most people never see what's happening underneath a concrete slab.

Yet beneath every slab is a system designed to manage ground movement, protect the structure, and influence long-term performance.

In Australia, reactive soils are a constant challenge — and what sits below the slab matters more than most realise.

Have you ever thought about what lies beneath your feet? Over the coming weeks, we'll be sharing how Cupolex works, where it's being used, and why foundation systems are becoming part of the sustainability conversation. Stay tuned for more insights!

One of the things we enjoy at OBAVIC is seeing how alternative building systems can achieve smarter outcomes.

By reducing the volume of concrete, Cupolex void formers can reduce material usage, improve sustainability and achieve a more consistent result. It also maintains the recyclability in the event of future demolition instead of diverting contaminated concrete waste to landfill like a conventional waffle slab.

For owner-builders, it’s a good reminder that there are often multiple ways to solve a design challenge. The key is ensuring that your choice is backed by proper engineering and certification, so it works effectively for your project and achieves building permit approval and design goals smoothly.

Exploring alternatives isn’t just about saving costs. It’s about designing better buildings. Cupolex Australia
