The Future Of Concrete Solutions
Rombus is a flexible pavement that works like asphalt but is stronger, lasts longer and is only 4cm thick. Rombus is a fast, clean, and affordable concrete solution.
Why Rombus?
Rombus is an eco-friendly solution made from recycled plastic, offering a greener alternative to traditional paving. It’s quick and easy to install, requiring less time and effort, and delivers a durable, dust-free, gravel-free surface that outperforms concrete and asphalt.
Endless Applications
Rombus Flexible Pavement is a smarter, more durable alternative to traditional concrete. Engineered for strength at just 40mm thick, it stands up to heavy machinery, harsh weather, and high-traffic use without the cracking, surface wear, or the costly repairs of standard slabs.
Proudly Australian-made, Rombus delivers long-lasting performance across industries like mining, construction, agriculture, and landscaping, proving you don’t need a thick slab to get serious strength!

Our team has pioneered a unique and effective approach to sustainable pavement solutions and concrete slabs, utilising recycled plastic, rubber, and other waste building materials to construct our primary product Rombus Grid –an alternative to asphalt and/or concrete.
Provide a stronger, greener, cheaper, and faster solution to the building industry.
Reduce carbon emissions by an average of 60%, generating carbon credits for businesses
Rombus Grid Specifications
Lightweight and measuring 1m by 1m Rombus Grid is extremely versatile and strong.
It’s also easy to pack and store on pallets and can quickly and easily be installed onsite.
With the concrete slab cost calculator for Australia, you can measure your effort and see just how much of an impact you can make on your next project. Rombus reduces the amount of concrete needed for a typical concrete slab by up to 60%. At only 40 mm thick and with a compressive strength of 107 Mpa excess concrete needed to build up the structure is eliminated.
By reducing the concrete slab thickness using Rombus you can save thousands of dollars on your concrete slab cost per m2 and make the change necessary to reduce carbon emissions.
What would a 60% cost reduction from traditional concrete mean to your bottom line? Feel great knowing that you are genuinely making a difference by using a product that has been 100% designed developed and manufactured in Australia, makes use of recycled plastics and is making a difference to our carbon reduction efforts and the war on plastic.
Reduce Concrete Slab Cost & Carbon Calculator
Are you looking to save on concrete costs while minimising your environmental impact? With the Rombus , you can save up to 60% on concrete costs and create a stronger, more durable modular pavement hardstand, outperforming traditional concrete slabs. You will also be contributing to a greener future! Significantly reducing your carbon footprint by cutting down on cement usage, lowering carbon emissions by as much as 65-95%.
Rombus Projects
Rombus Grid is an innovative “Modular Pavement Technology” which is the first of its kind with outstanding capabilities. It has been engineered for use in a wide range of applications as a cheaper and more sustainable substitution for even the thickest of concrete slabs. This job was for Lift Equipt in Bibra Lake. There was no access to the yard where heavy machinery needed to be stored.
Rombus is revolutionising concrete with a greener, smarter alternative. Cement is a major source of global emissions—Rombus changes that with a 100% Australian-made recycled plastic grid system that’s stronger, faster, and more sustainable than traditional slabs. At just 40mm thick, each 1m² grid uses 5.4kg of recycled plastic and, when filled with 32MPa concrete, supports over 10,000 tonnes per square metre
