Rombus
A modular pavement system engineered for heavy-use surfaces in demanding environments
Rombus combines a 100% Australian recycled plastic grid with a reduced-depth concrete infill to create a high-strength flexible pavement system. Designed as an alternative to full-depth slabs, it reduces excavation, concrete volume, steel reinforcement and installation time while delivering durable surface performance for hardstands, pavements, access roads and industrial areas. Tested load performance exceeds 10,000 tonnes per square metre.
For Industries That Need Stronger, Cleaner Ground Support
Rombus is designed for sites where traditional concrete, gravel and asphalt can become costly, slow or difficult to maintain. From Agriculture and Construction to Landscaping, Transport, Logistics and Mining, Rombus creates durable, dust and gravel-free surfaces with less excavation, less concrete and faster installation.

Industrial Slab Performance, Reimagined
From Grid to Industrial Grade Surface
At the Manawatu Cold Storage facility in Feilding, NZ, Rombus was installed as a faster, lower-concrete alternative to traditional slab construction.
Rombus is capable of delivering high-performance slab systems for large-scale industrial facilities. Watch the pour process to see how the grid is filled, finished and transformed into a durable industrial surface.
Concrete is poured into interlocking grid system, it absorbs movement and distributes pressure, to reduce cracking.



ROMBUS FUSION V2 EMPTY GRID
48mm Hexagonal Grid Profile
Each Fusion V2 sheet measures 1166mm × 1166mm × 48mm, with a gross sheet area of 1.36m² and approximately 6kg weight per grid with 48mm concrete fill depth.
FINISHED SURFACE
Smoother Connected Finish
Fusion V2 uses an upgraded hexagonal cell structure with overlapping joins to create a more continuous surface finish. The system is designed to improve load distribution and reduce system-wide stress across high-traffic and fatigue-prone areas.
COMPLETED PROJECT
Designed to Streamline Installation
Fusion V2 is designed to cover more ground per sheet, eliminate the need for expansion joints and reduce installation complexity. It requires approximately 4.6m³ of concrete per 100m², helping deliver a durable pavement surface with less concrete than traditional full-depth slabs.

ROMBUS V1 EMPTY GRID
40mm Diamond Grid Profile
Each Grid V1 sheet measures 1000mm × 1000mm × 40mm, with 1m² gross area, approximately 5.35kg weight per grid and 40mm concrete fill depth.
FINISHED SURFACE
Diamond Pattern Surface
Rombus Grid V1 creates a structured diamond-pattern finish once filled with concrete, providing a strong, lower-concrete alternative to traditional full-depth slabs.
COMPLETED PROJECT
Tested Load Bearing Performance
Grid V1 is installed using a three-stage process: ground preparation, grid installation and concrete infill using the approved 32MPa mix design.
The system has been tested to withstand loads exceeding 10,000 tonnes per square metre.

What is Rombus Flexible Concrete?
Rombus is a modular flexible concrete pavement system engineered for agricultural, industrial and commercial load-bearing applications. It combines a recycled plastic grid structure with a reduced-depth concrete infill to create a durable, high-performance surface that reduces concrete volume, excavation, formwork and installation requirements compared with traditional full-depth concrete slabs.
How does freight work for Rombus?
All Rombus orders require a freight quote from our sales team. Follow the links provided on product page to submit a request.
What is the difference between Rombus Grid V1 and Fusion V2?
Grid V1 is a 1000 × 1000 × 40mm diamond-pattern panel with 1m² coverage per sheet. Fusion V2 is a 1166 × 1166 × 48mm hexagon-pattern panel with 1.36m² coverage per sheet and overlapping joins for a continuous connected surface. Both systems are designed to reduce concrete volume and installation requirements compared with traditional full-depth slabs.
