Rombus Grid V1
Same Strength. Less Concrete. Faster Installation.
The original Hybrid Pavement Technology. A modular, flexible system engineered as a high-performance alternative to traditional full-depth concrete slabs.
At only 40mm deep, Rombus Grid V1 delivers exceptional strength while significantly reducing concrete, excavation and installation requirements.
- Tested to withstand loads exceeding 10,000 tonnes per m²
- Only 40mm deep
- Approx. 3.8m³ of concrete per 100m²
- Fast, simple three-stage installation
- Reduced excavation and site preparation
- Lightweight 1m² grids for easy handling and installation
- Made using locally recycled polypropylene
- 100% Australian owned, designed and manufactured

Rombus Installation
How it works
Step 1
Lay the Rombus Grid onto a level surface
Step 2
Pour the concrete over the grid
Step 3
Use a vibrator to settle the concrete evenly with the top of the grid
Step 4
Trowel down the surface until you can see each and every individual cell
140%
Quicker installs
33%
Less Labour
Rombus is available in two versions: Grid V1 & Fusion V2
Which Rombus System Suits Your Project?
Both systems create durable, load-bearing surfaces using less concrete than traditional full-depth slabs.
The comparison below will assist in understanding key differences between each version to determine which option may be better suited to your site, installation and load requirements.

Yes. Expansion joints every 20 m² to ensure stability and long-term performance
No. Overlap joins so no edging required
Fast efficient installs without compromising strength or durability
Stronger, smoother and designed for heavier loads
Exceptional load capacity
Handles up to 10,900 tonnes per m² when filled with concrete.
Modular, flexible concrete
Outlasts and outperforms traditional concrete and asphalt systems.
Innovative grid-cell structure
A revolutionary modular design that delivers durable, dust-free, and gravel-free surfaces for industrial environments.
Faster installs
Versatile grid system installs up to 40% faster and requires 30% less labour.
Fewer deliveries, less material
40mm profile height significantly reduces concrete volume compared to conventional slabs.
Minimal downtime
Achieves full strength up to 75% faster than a 120mm traditional slab, allowing earlier access and reduced program delays.
Reduced carbon footprint
Low-profile 40mm design cuts embodied carbon by reducing concrete consumption across every installation.
Recycled materials
Each square metre of Rombus incorporates 5.4kg of 100% responsibly sourced recycled plastic, diverting waste from landfill.
Engineered for diverse sectors
Suitable for mining, construction, agriculture, storage, landscaping, and public infrastructure.

Heavy-Duty Warehouse Flooring
$500,000 Saved
Rio Tinto’s Hope Downs 4 Mine Warehouse needed a sealed, dust-free floor, but extensive slab damage and an unstable subgrade initially pointed to a full demolition and rebuild as the only viable solution. Rombus provided a saving ~$480,000 and 127 tonnes of CO₂ emissions while reducing downtime by 20 days.

Got a question? We're here to help.
What is Rombus?
An Australian-made modular pavement system that replaces traditional concrete slabs. Lightweight, flexible, and strong enough to handle 10,000+ Tonnes per m².
How does it work?
Rombus grids interlock and are filled with 4-4.8mm of concrete, creating a high-strength, low-thickness slab that installs quickly and performs for decades.
Where is Rombus made?
Rombus is manufactured in Australia from 100% recycled polypropylene.
What are the main benefits?
The system uses up to 90% less concrete, making it faster to install, more sustainable, and far better for the environment. The interlocking grids mean minimal downtime and long-term durability, built to last.
What’s the difference between Rombus Grid (V1) & Fusion (V2)?
Rombus Grid: 1000mm X 1000mm X 40mm, diamond-pattern, edging required, and expansion joints every 20 m² to ensure stability and long-term performance. Weight: 5.4kg Gross area per sheet: 1m2
Fusion V2: 1166 X 1166m X 48mm, hexagon pattern, overlaps so no joins or edging required. Weight: 6.1kg Gross area per sheet: 1.36m2
Has it been proven in the field?
Rio Tinto’s Hope Downs 4 Mine - Warehouse needed a sealed, dust-free floor, but extensive slab damage and an unstable subgrade initially pointed to a full demolition and rebuild as the only viable solution. Rhombus provided a saving ~$480,000 and 127 tonnes of CO₂ emissions while reducing downtime by 20 days. Link to case study
Aurizon’s Kalgoorlie Container Terminal - Rombus replaced damaged concrete with a fast, modular system that saved $350,000, cut over 172,000 kg of CO₂, and had the site operational again within seven days. Link to case study
