Marshalls Grassguard Permeable Paving: How It Works, Sizes & Best Uses

Marshalls Grassguard is a reinforced grass paving system designed for projects that need a usable access or parking surface without covering the whole area in conventional hard paving. The concrete grid supports the surface while allowing grass to grow through the openings, creating a greener finish and helping water pass through the paved area.

How Does Grassguard Work?

Grassguard uses open concrete paving units that are laid as part of a correctly designed build-up and then filled to allow grass growth through the surface. The concrete provides structural reinforcement while the open sections help retain the appearance of a grassed area.

This makes it useful for locations where a fully paved driveway or parking area would look too hard or where a more permeable surface is preferred.

Grassguard 130, 160 and 180

The range is available in three main specifications:

• Grassguard 180: 600 x 400 x 120mm, covering 5.76m² per pack.
• Grassguard 160: 600 x 400 x 120mm, covering 5.76m² per pack.
• Grassguard 130: 500 x 300 x 100mm, covering 9.60m² per pack.

The correct option will depend on the project specification, required loading and installation design, so it is important to confirm the exact requirement before ordering.

Where Is Marshalls Grassguard Best Used?

Grassguard is suited to parking areas, landscaped access routes, occasional vehicle overrun areas and reinforced grass spaces. Marshalls' product guidance states that Grassguard should be used in areas with occasional vehicle overrun rather than treated as a conventional continuously trafficked road surface.

It can be particularly effective on developments where designers want to reduce the visual impact of large hard-paved areas while still providing practical vehicle access or overflow parking.

Permeable Paving and Surface Water

Because the surface remains open between the concrete sections, Grassguard can help water pass through the paved area instead of creating the same level of surface run-off associated with a fully sealed hard surface. The performance of the system still depends on the complete installation build-up beneath the paving, so drainage should be considered as part of the overall project design.

What Colour Is Grassguard?

The paving itself is supplied in Earth Brown, helping the concrete units sit more naturally within the finished grassed surface as vegetation establishes through the grid.
