Naylor GroundGrid Plus Gravel Grid – 40mm x 500mm x 500mm – Black

The Naylor GroundGrid Plus (MetroPave Plus) Gravel Grid 40mm x 500mm x 500mm Black is a heavy-duty cellular paving system engineered for commercial, industrial and high-traffic applications. Manufactured in the UK from 100% recycled plastic, GroundGrid Plus delivers exceptional load-bearing performance while creating a permeable, environmentally responsible surface suitable for gravel or grass finishes.

Designed for commercial car parks, access roads, overflow parking areas and service routes, GroundGrid Plus offers significantly greater strength than standard gravel stabilisation grids. When correctly installed, it can withstand axle loads of up to 60 tonnes, making it suitable for regular vehicle traffic and occasional HGV access. The reinforced cellular structure distributes loads evenly across the surface, helping to prevent rutting, settlement and gravel migration.

The fully permeable design allows rainwater to drain naturally through the surface and into the ground below, reducing surface water runoff and supporting Sustainable Drainage Systems (SuDS). Whether filled with decorative gravel or grass, GroundGrid Plus creates an attractive, durable and low-maintenance surface that blends seamlessly into its surroundings.

GroundGrid Plus can be installed on slopes of up to 15 degrees without additional staking or pinning. For steeper embankments and specialist applications, additional fixing methods can be used to provide enhanced stability. The modular interlocking design enables fast installation and easy adaptation around curves, edges and site obstacles.

Naylor GroundGrid Plus Gravel Grid Installation Overview:

GroundGrid Plus should be installed over a free-draining sub-base with a geotextile separation layer and suitable bedding material. For gravel applications, a 30mm compacted layer of 5mm grit is recommended beneath the grid, with 5mm to 15mm angular gravel used as the infill. The interlocking design allows rapid installation while providing exceptional long-term stability and load distribution. Read more on the Manufacturer Website
