GridMats® OC (Open Cell)
40 MM Heavy Duty
What is it?
GridMats® OC (40 mm Heavy Duty) is a high‑load open‑cell paving system built to withstand demanding conditions, including industrial roads, bus depots, and heavy vehicle parking.
Each panel is crafted from recycled plastic and features an interlocking grid that can be filled with concrete, asphalt, or gravel. This design reduces the need for rebar and large concrete pours while delivering exceptional load support and reduced maintenance.
Use Cases
Heavy Industrial Roads
​Load zones for factories, mining sites, or shipping yards that handle frequent truck, forklift, or container movement.
High‑Traffic Commercial Areas
Warehouses, logistics hubs, or distribution centers needing robust, semi‑permanent surfaces without the hassle of full concrete roads.
