Cupolex® Concrete Forming System
Cupolex is lightweight, easy to install, and generates minimal on-site waste.
Cupolex® is an innovative, eco-friendly concrete slab forming system made from 100% recycled plastic. It replaces traditional polystyrene pods with a dome-shaped design that forms a voided slab—reducing concrete and steel use while improving strength and durability.
The system creates an under-slab void that helps manage moisture, vapour, and gases like radon. This makes it ideal for residential, commercial, and industrial builds, especially where ventilation or ground contamination is a concern.
Cupolex is lightweight, easy to install, and generates minimal on-site waste. The pods interlock without cutting, speeding up slab preparation and reducing labour costs. Accessories such as Beton Stops, Flat Stops, Reinforcing Chairs, and Load Spreaders ensure a complete and reliable system.
Cupolex Ecodome R-Value Calculator
Unlock the full thermal performance of your Cupolex Ecodome system with our intuitive R-Value Calculator. Designed for architects, engineers, builders, and specifiers, this tool provides fast, accurate insights into the insulation performance of your Cupolex foundation design.
The calculator analyses key project inputs — including slab depth, fill material, ventilation conditions, and Ecodome configuration — to generate a precise R-Value estimation in line with New Zealand building standards. Whether you’re designing for residential, commercial, or high-performance energy-efficient builds, our calculator helps you plan with confidence and optimise thermal efficiency from the ground up.
Environmental Benefits
The system is presented as an eco-friendly alternative, as it uses locally sourced recycled materials for the construction of the dome-shaped pods.
Structural Strength
The patented design of the Cupolex pods offers superior structural strength, providing stability to the overall concrete floor system.
Installation Ease
The interlocking design of the pods allows for easy and quick installation, potentially reducing construction time and labor costs.
Transport Efficiency
The stackable nature of the Cupolex pods makes transportation more efficient and helps save space during shipping and storage.
Supporting Components
The Cupolex system includes components like Beton Stops (for pod spacing), Flat Stops (for leveling), Reinforcing Chairs (for supporting steel), and Load Spreaders (for load distribution)—all working together as a complete concrete floor solution.
Engineering Approval
The system meets engineering standards, with concrete type and details typically specified by a Chartered Professional Engineer or reference document.
