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
Rombus Features
ENGINEERED STRENGTH
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.

Rombus Grid Features
EFFICIENCY AT EVERY STAGE
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.
Rombus Grid Features
ENGINEERED SUSTAINABILITY
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.

Case Study
Rio Tinto Hope Downs 4 Rio Tinto Mine
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.
Frequently asked questions
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
