The road of the future is here.
Stronger. Faster. Greener. Cheaper.
Rombus surface.
-
Commercial
Need an unbreakable road or factory floor?
-
Agricultural
Fast, simple and efficient hard stands ideal for shed floors, wash bays, stockyards, feedlots, and driveways. Let us fix those farm headaches.
-
Residential
Get it done once. Tricky terrain no problem.
-
Retail
Need a floor as strong as it is aesthetic?
The Rombus flexible surface solution is a
dust-free, gravel-free wearing course
that serves the same function as asphalt or concrete slabs,
only with superior wearing and strength properties.
It is the first flexible pavement system with a hard concrete surface.
Installation is an easy 3 stage process consisting of ground preparation,
grid install and fill, then finish with Rombus approved mix design and desired finish.

STRONG
Stronger than traditional tarmac and concrete surfaces, Rombus is able to handle 10,900 tonnes of compressive strength per m2 when filled with concrete, and an impressive 4,000 tonne per m2 when using granular materials such as road base or limestone aggregates. Rombus has concrete interlocking key joints between each sheet, so whilst modular to install, it becomes one very strong surface once the concrete has cured.

GREEN
Designed and manufactured in Australia using 5.4kgs of 100% locally sourced recycled plastic per m2, and at only 40mm thick Rombus reduces the amount of concrete needed by a minimum of 60%, along with the associated carbon emissions. Less concrete also means less water usage. We can calculate the emissions savings on your next project.

FAST
Rombus can be laid and ready to go far quicker than a traditional tarmac or concrete surface. Our incredibly versatile grid is easily deployed, installed and can be removed in situ, saving considerable time and hassle compared to full-depth work.

CREATIVE
Using coloured fill, we’re more than hapy to work with you on creative requests.

STYLISH
If you’re looking for something a little more interesting from your concrete floor, Rombus can be honed and polished.

PERMEABLE
Rombus can easily be used as a drainage solution within a pavement by using permeable aggregates in nominated areas. This is increasingly necessary to protect against flooding effects of climate change.

AFFORDABLE
Requiring a mere 0.04 m3 of concrete per square meter to achieve strengths superior to a traditional concrete slab, Rombus is a cheaper solution.

FLEXIBLE
Depending on your use case, you can fill the Rombus grid with anything from air to soil to concrete to recycled crushed concrete! It can be filled with permeable or impermeable materials. It can accommodate significant deflections under load.
problems we solve:
-
poor drainage
Whether it be a suburban path or remote feedlot, poor drainage and erosion can cause expensive headaches such access issues, hardstand collapse and surface failures. Rombus can be filled with permeable fill to avoid these issues and their associated expense.
-
dust management
Uncontrolled dust also contributes to challenging and expensive health and equipment maintenance problems.
-
cost saving
Particularly when jobs are regional or remote, costs can blow out if not completed efficiently. Rombus is modular, making for much faster installation times and reduced construction schedules.
Less concrete and no formwork or steel ties are a cost-saver, and because concrete trucks can drive onto the empty grid, the significant cost of a concrete pump can be avoided. -
failing pavements
An all-too-common occurence that can easily be prevented using Rombus. Not only are pavement fractures are hazardous and can interrupt business and access.
-
safer work
The Rombus grid weighs 5.4 kg per 1m2 sheet, saving employees the heavy and awkward task of working with steel mesh. There is also less concrete to move around. Both of these things make work easier and safer.
WHY IT MATTERS
Roads and pavements form a large part of the urban environment. Cement is responsible for 6-8% of the worlds carbon emissions.
Replacing traditional concrete slabs and pavements with Rombus hybrid
pavement system can reduce your carbon footprint by up to 90%.
Reducing concrete in these will lower carbon emissions, conserve resources, improve air quality
and lower construction costs.
In some applications, you may want to do away with concrete altogether!
Rombus is a less dense structure drawing and releasing heat into the atmosphere.
In this way, Rombus can keep suburbs cooler.
We need to reduce the amount of concrete we use. Rombus is one significant way to do that.

In airport surfaces, any CASA approved methods may be applied. The product would be suitable for taxiways and aprons, however consideration is required for the application in the touchdown areas of runways where further analysis will be required. In any airport runway application, either flexible or bound, design shall be undertaken in accordance with Civil Aviation Safety Authority (2011) Advisory Circular Strength Rating of Aerodrome Pavements.
