How it compares

Diamond Grid™ against the three surfaces it usually replaces.

	Concrete	Concrete slabs / pavers	Asphalt	Diamond Grid™
Longevity	15–20 years	10–15 years	5–10 years	30+ years
Materials required	Cement and steel mesh, framework required	Pre-cast cement slabs	Asphalt mixture (tar and aggregate)	100% recycled polypropylene
Maintenance	Low — prone to cracking and becoming unlevel	Low — can become cracked and unlevel	High — top seal every 2–3 years	Very low — may need some gravel or grass upkeep
Cost & appearance	Black, uniform, industrial, high cost	Options available at a cost	Uniform, options at a higher cost	A variety of low-cost fills that blend into the environment
Permeability	N/A	15–30%	N/A	Up to 100%
Depth	3–11" depending on application	4–6" depending on application and loads	Average 4–4.5"	1–2"
Eco friendliness	High impact, not recyclable or reusable, high ground runoff	High impact, not recyclable, needs waste disposal if removed	High impact, oil-based derivatives, not recyclable or reusable	Low impact — recycled, movable, reusable, low runoff

Case studies

A selection of Diamond Grid™ installations from the product brochure.

Concrete hardstand

6,000 m²

Challenge: A cost-effective, durable solution to support heavy mining equipment at a heavy haulage facility.
Solution: Diamond Grid™ saved 65% over traditional concrete, with a tailored pavement plan, proper subbase prep and efficient installation.
Outcome: A robust, low-maintenance surface that handles heavy loads and lifts operational efficiency.

Heavy vehicle workshop slab

2,500 m²

Challenge: A durable workshop floor for heavy mining equipment, facing high costs and long construction times with traditional concrete.
Solution: Diamond Grid™ was installed over compacted road base and completed in 2–3 days.
Outcome: Operational within 7 days, reducing costs and disruption.

Industrial lay-down area

12,000 m²

Challenge: A reliable all-weather pavement to support heavy machinery and forklifts, minimising downtime.
Solution: A Diamond Grid™ unbound pavement gave a cost-effective, tough surface with quick installation.
Outcome: A low-maintenance pavement, operational within 7 days.

CHPP pavement solution

Challenge: A sealed pavement around the fixed plant to improve safety, manage coal spills and reduce water accumulation with minimal operational disruption.
Solution: Diamond Grid™ delivered a 78% cost saving over concrete, with quick sectional installation for a sealed, easy-to-clean surface.
Outcome: A safer, low-maintenance pavement installed with minimal disruption.

Holiday park turf stabilisation

1,050 m²

Challenge: A reinforced grass surface to withstand heavy foot and vehicle traffic while keeping a natural look.
Solution: Grass-filled Diamond Grid™ was installed for stability, erosion control and improved drainage.
Outcome: A long-lasting surface that preserves natural grass while preventing rutting and wear during peak use.

Remote private access road

350 m

Challenge: A sandy road with steep inclines needed a durable solution to improve access, withstand harsh weather and minimise maintenance.
Solution: Diamond Grid™ was installed and filled with aggregate, improving surface stability, load-bearing capacity and erosion resistance.
Outcome: Quick installation, improved terrain stability and reduced long-term maintenance.
