No Project Too Big Or Too Small

CUPOLEX® is the world’s leading smart void former made from 100% recycled plastic.

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. 

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.

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.


Covi Constructions

“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.

Jamie Macdouall

Project Manager, BT Homes

“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.
