No Project Too Big Or Too Small
CUPOLEX® is the world’s leading smart void former made from 100% recycled plastic. As a proven alternative to custom moulded polystyrene, it delivers strong environmental and structural performance across all project types.
Made in Australia with local distribution, CUPOLEX® are suitable for residential, commercial or industrial applications.
The 100% recycled non-toxic polypropylene domes interconnect to create a self supporting structure. The CUPOLEX® concrete slab system can also provide significant reductions in the volume of concrete, reinforcing steel and labour required to put the system down.
Because Cupolex produces negligible waste and debris that can escape site boundaries, EPA penalties are minimised. With no need for cutting or shaping on-site, it also avoids the mess typically associated with polystyrene recycling.
The stack-ability of the domes in transit means that you also save on transport costs. This also decreases site traffic and makes delivery a far less complicated procedure. Cupolex delivers project savings in many ways.

Moisture Protection and Air Quality
Cupolex improves slab performance by limiting ground contact and managing moisture beneath the structure. The under-slab void prevents water from wicking into the concrete, reducing the risk of mould, mildew and flooring damage. Venting the cavity helps control humidity, temperature and airborne pollutants. It also allows for passive ventilation of vapours like VOCs or methane, making it well-suited for reclaimed or high-risk sites with environmental concerns.
Sustainability in Construction
Cupolex is made from 100% recycled, non-toxic polypropylene and supports sustainable building practices. It is also an environmentally superior option to polystyrene recycling systems, eliminating mess, residue and landfill contribution. By replacing materials like custom moulded polystyrene (waffle pod)with a fully recyclable solution, Cupolex helps future-proof projects against rising sustainability standards.
Cost Advantages with Cupolex
Cupolex helps reduce overall construction costs by cutting down on materials and labour. The system lowers the volume of concrete and reinforces the steel needed, while quick installation reduces time on site. It also eliminates the need for compaction or heavy machinery. One pallet of Cupolex replaces up to 27.5 cubic metres of compacted fill, with no trucks, no compaction and no certification required.

Benefits of Using Cupolex
Here are the key advantages that make Cupolex a smarter choice for modern construction:
- Ready to install — Each component is delivered to site pre-packaged and ready to go. There’s no cutting, trimming or shaping required, which helps reduce mess and streamline installation.
- Soil adaptability — The system is engineered to suit all soil classifications without the need for custom adjustments. This makes planning easier and avoids delays caused by unexpected ground conditions.
- Strong underfoot — Cupolex domes are solid and stable, designed to hold their shape during placement. This reduces trip hazards and provides a safer working surface for crews during slab preparation.
- Low glare finish — Unlike polystyrene pods that reflect sunlight and create intense glare, Cupolex components are black and non-reflective. They’re easier and safer to handle under bright Australian conditions.
- Polystyrene-free system — Made from 100% recycled polypropylene sourced in Australia, Cupolex avoids the mess and environmental impact associated with polystyrene recycling. There’s no loose foam, no site debris and no cutting waste.
- Award-winning product — Cupolex has been recognised in Australia and internationally for its contribution to sustainable building practices. Awards include GreenSmart Sustainable Home of the Year and Best Environmental Product at Civenex Sydney.

Client Testimonials
“I have estimated we save at least 8-man hours per slab with not having to bar chair the H260 domes and clean up mess as you do with other systems. We no longer need to be so worried about the penalties from local councils for waste being blown off site.
“We have been using Cupolex for over 2 years now and are always totally impressed with how quick and easy it is to use. The Cupolex system is definitely the way to go for saving time and money as well as being great for the environment.”
“We made the decision to try the Cupolex System on a Job in Forbes this week. We have found that by using Cupolex we have saved dramatically on labour costs and have found this a very fast and efficient means of preparing a slab…. We have already scheduled for all our slabs to change over to Cupolex.”
“We find it is cost effective in comparison to the waffle pods and much easier and cleaner to work with. The Cupolex team are super helpful and gave our concreters all the training to install the product. We are very happy and highly recommend this slab system.”
