The actual depth is 40mm/4cm. On the top of the grid moulded into the design, are anti slip nodules to prevent slipping in icy conditions.
For a discrete looking finish, we recommend using 30kg of 10mm or 20mm gravel per grid. If you wish to see the top of the grids, we recommend 20kg of 10mm or 20mm gravel per grid.
None at all other than what you want to choose to fill them.
Per square metre, the grids can withstand weights of 500 tonnes. So forklift trucks and large artic lorries have no problem as they daily drive over them to collect and deliver multiple pallets from our factory.
The grids are designed with interlocking clips pre-moulded into all four sides of the grids, so you can assemble large areas in minutes.
One full stacked pallet measures 1.2m x 1m x 2.4m
