Large-scale construction projects require careful planning and expert execution. Every aspect, from material selection to logistics, downtime and labour costs, significantly impacts the project’s timeline and budget.
For a long time, construction companies had few alternatives for big-ticket line items. For example, the high costs and long timelines for concrete pavement were seen as unavoidable.
But that’s all changing thanks to the emergence of cost-effective alternatives to traditional concrete slabs and paving in Perth.
Rethinking concrete pavement: The need for smarter solutions in large-scale construction
Conventional concreting methods demand significant labour, large volumes of costly materials and lengthy curing times. These challenges add up quickly.
However, there hasn’t been a better alternative. Cheaper materials weren’t strong enough. Stronger solutions were too expensive. Innovative materials weren’t adaptable to different environments and applications.
Until now.
Rombus concrete grid solutions offer a modern, efficient alternative that can save both time and money.
Rombus not only outperforms traditional paving in terms of strength, sustainability and efficiency. But those benefits also scale up to meet the needs of commercial, industrial, mining and civil construction projects.
Understanding Rombus concrete grid solutions
Rombus concrete grid is an innovative hybrid pavement system. Made from 100% recycled co-polymer propylene, the modular design is engineered to be lightweight yet incredibly strong.
Unlike conventional paving, Rombus concrete grids don’t require any formwork or steel reinforcement. That’s one reason it becomes more cost-effective over large expanses.
Rombus is also easy to work with, fast to install, and offers superior strength and durability in a range of applications.
Bottom line? Rombus helps you control costs, stay on schedule, and achieve exceptional performance in Perth paving projects.
Superior strength
Once installed and filled with a Rombus-approved mix design, our concrete slab system yields a compressive strength of 107 Mpa (10,900 tonnes per m2). That’s two to five times higher than concrete typically used on hardstands and day yards.
When filled with granular materials like road base, aggregate or limestone, Rombus concrete grid has an impressive 40 Mpa (4,000 Tonnes per m2) compressive strength.
Unlike traditional concrete, this strength doesn’t deteriorate. The recycled plastic material used to form the grid system is not subject to cracking, wear and tear or erosion.
Faster, cheaper installation
With a simple three-step installation process, the Rombus system eliminates the need for complex equipment like earthmovers and pump trucks:
- Ground preparation: The 40mm thickness means less earthworks and no need to remove the existing wearing course
- Grid placement: An innovative modular design means Rombus can be assembled quickly without requiring any specialised skills
- Filling: Rombus reduces cement requirements by up to 60% and can be spot-filled with permeable materials to allow for drainage
Rombus grids are stackable on pallets for cost-effective transport. The modular design allows for quick assembly. And the significant reduction in cement means shorter curing times.
All said and done, this streamlined process reduces installation times by up to 40%.
Material cost savings
Traditional concrete slabs require substantial volumes of concrete and additional reinforcement materials like steel mesh. Rombus, you’ll use significantly less concrete, reducing material expenses by up to 50% per slab.
- Traditional concrete pavement: 100m² = 10m³ of concrete
- Rombus concrete grid: 100m² = 4m³ of concrete
By cutting concrete requirements, your projects become both cheaper and greener.
Plus, laying a Rombus slab requires 33% less labour than conventional concrete pavement. That figure is even higher when preparing challenging sites. Rombus is 11% the thickness of traditional slabs (40mm compared to 350mm), meaning less earthmoving is required.

Less long-term maintenance
Rombus concrete grids offer exceptional durability compared to concrete. The recycled polypropylene is non-reactive, resists cracking, chemical exposure and weather, and is proven to withstand heavy equipment.
We have completed several Perth paving projects that are still going strong after years of use and abuse.
The modular design also simplifies sub-grade repairs, allowing for non-destructive maintenance.
This leads to significant cost savings over the long term. Plus, the modular design means you can repurpose the material. It’s perfect for semi-permanent applications like mine road access and temporary driveways.
Environmental and regulatory advantage
Sustainability is central to our mission at Rombus Industries. In developing a superior solution for paving in Perth, we are also addressing the planet’s greatest recycling challenges.
The result is a sustainable product that meets the needs of modern construction projects.
- 100% recycled: Rombus is made in Australia using recycled plastic, rubber and other waste-building materials, diverting these non-degrading materials from landfills.
- Curbing cement emissions: Cement makes up around 8% of global CO2 emissions and is a major ingredient in concrete, meaning every m3 you save with Rombus is reducing your emissions.
- Generating carbon credits: Reduce your concreting carbon emissions by 60% on average, generating carbon credits for your business.
- Reusable: You may be able to repurpose the modular concrete grid, reducing the demand for primary materials.
Together with the end-to-end efficiencies – less heavy equipment required, easier transportation, less earthmoving and better erosion control – Rombus is helping the Australian construction sector to combat climate change in every project.
