GRASSRINGS Black Grass Protection System – 30mm x 500mm x 500mm – Pack of 4 (1m²)

GRASSRINGS is a heavy-duty grass protection and reinforcement grid designed to create durable, permeable parking areas, driveways and vehicle access routes while maintaining a natural grass surface. Supplied as a pack of four 500mm x 500mm grids covering 1m², the 30mm deep system provides a load-bearing capacity in excess of 350 tonnes per m² when correctly installed and filled.

Manufactured from 100% recycled, UV-stabilised HDPE, GRASSRINGS provides long-term reinforcement for grassed areas subject to vehicle and pedestrian traffic. The open cellular design provides over 90% root development area and 100% grass reinforcement coverage, allowing grass roots to grow laterally while helping to prevent damaging compaction of the root zone.

The individual 500mm x 500mm grass grids simply clip together before being laid over a correctly prepared stone sub-base. Once filled with a suitable topsoil and growing medium and seeded, the grids become integrated into the grass surface to provide a strong, stable and attractive permeable parking or access area.

What Are GRASSRINGS Used For?

GRASSRINGS grass reinforcement grids can be used anywhere a stable load-bearing surface is required while retaining grass and natural drainage.

Typical applications include:

• Grass driveways
• Residential parking areas
• Overflow car parks
• Occasional parking areas
• Commercial parking
• Vehicle access routes
• Caravan and motorhome parking
• Holiday parks
• Campsites
• Event parking
• Grass verges
• Emergency vehicle access
• Garden access routes
• Commercial developments
• Landscaped parking areas

The system can help increase usable parking or vehicle access space without covering the area with a conventional impermeable hard surface.

Are GRASSRINGS Suitable for Grass Parking?

Yes. GRASSRINGS are specifically designed to reinforce grass used for vehicle parking and access.

When installed over a suitable prepared stone sub-base, the grids distribute loads across the reinforced surface while protecting the underlying grass root zone from excessive compaction.

The open grid design allows the cells to be filled with an appropriate growing medium and seeded. As the grass establishes, the surface retains a predominantly natural grass appearance while the GRASSRINGS beneath provide structural reinforcement.

This makes the system particularly useful for occasional parking, overflow car parks and additional residential parking where maintaining green space is desirable.

Can GRASSRINGS Be Used for a Grass Driveway?

GRASSRINGS can be used to create reinforced grass driveways and vehicle access routes, provided that the ground and sub-base are correctly prepared for the anticipated vehicle loading.

The grids should be installed over a suitable stone sub-base before being filled with the correct topsoil or growing medium and seeded.

Correct preparation of the sub-base is essential because it provides the underlying structural support and drainage required for the completed grass reinforcement system.

How Much Area Does One Pack of GRASSRINGS Cover?

Each GRASSRINGS panel measures:

500mm x 500mm x 30mm

A single panel therefore covers:

0.5m x 0.5m = 0.25m²

Each pack contains four panels:

4 x 0.25m² = 1m²

You therefore need one pack of four GRASSRINGS for every 1m² of area before allowing for cuts or wastage.

Example GRASSRINGS Quantity Calculation

For an area measuring 5 metres long by 3 metres wide:

5m x 3m = 15m²

As each pack covers 1m²:

15m² = 15 packs of GRASSRINGS

Additional material may be required for cuts, edges and irregularly shaped areas.

How Strong Are GRASSRINGS?

When correctly installed and filled with the appropriate topsoil and growing medium, GRASSRINGS have a stated load-bearing capacity in excess of 350 tonnes per m².

The circular cellular structure is designed to provide substantial reinforcement while maintaining a large open area for grass growth.

Actual performance of the completed surface depends on correct ground preparation, sub-base construction, installation and filling of the grids.

Do GRASSRINGS Allow Grass to Grow?

Yes. GRASSRINGS have been specifically designed to combine structural reinforcement with healthy grass growth.

The open grid provides over 90% root development area, allowing grass roots to spread laterally through the system rather than being restricted within small individual cells.

The grids also help prevent excessive compaction of the root zone caused by vehicles. This allows the roots to continue accessing the oxygen, moisture and nutrients required for healthy grass growth.

Once properly established, the grass grows through and around the reinforcement grid to create a predominantly natural grass surface.

Are GRASSRINGS Permeable?

Yes. GRASSRINGS create an open, permeable reinforced surface rather than covering the ground with an impermeable material.

Water can pass through the grass and growing medium into the underlying construction, subject to the permeability and drainage characteristics of the complete installation.

This makes grass reinforcement grids a useful alternative to conventional hard surfacing where maintaining natural drainage and green space is an important consideration.

How Are GRASSRINGS Installed?

GRASSRINGS are designed for straightforward installation over a suitable prepared stone sub-base.

The 500mm x 500mm panels use an integrated clipping mechanism to connect adjacent grids and create a continuous reinforced surface.

Once installed, the grids are filled with a suitable topsoil and growing medium before being seeded.

The flexibility of the system allows the grids to follow gentle contours in the ground. Individual panels can also be cut where necessary, while joints can be staggered to accommodate curves and irregular boundaries with minimal waste.

Correct sub-base preparation is essential for achieving the intended strength, stability and drainage characteristics of the finished surface.

Frequently Asked Questions

How many GRASSRINGS do I need per square metre?

Each GRASSRINGS panel measures 500mm x 500mm and covers 0.25m². You therefore need four panels per square metre. This product is supplied as a pack of four panels covering 1m².

Can GRASSRINGS be used for car parking?

Yes. GRASSRINGS are designed for reinforced grass parking and vehicle access areas. They are suitable for residential and commercial applications when installed over an appropriate sub-base.

Can I use GRASSRINGS for a grass driveway?

Yes. GRASSRINGS can be used for grass driveways and vehicle access routes, subject to correct ground preparation and installation for the anticipated loads.

How much weight can GRASSRINGS support?

GRASSRINGS have a stated load-bearing capacity of more than 350 tonnes per m² when correctly installed and filled with the appropriate topsoil and growing medium.

What are GRASSRINGS made from?

GRASSRINGS are manufactured from 100% recycled, UV-stabilised high-density polyethylene (HDPE).

What size are GRASSRINGS?

Each grass reinforcement grid measures 500mm x 500mm and is 30mm deep, with a cell diameter of approximately 50mm.

How many GRASSRINGS are in a pack?

Each pack contains four 500mm x 500mm GRASSRINGS panels, providing a total coverage of 1m² per pack.

Are GRASSRINGS permeable?

Yes. The open-grid structure allows water to pass through the grass and growing medium rather than creating a conventional impermeable surface.

Can grass roots grow through GRASSRINGS?

Yes. The system provides over 90% root development area, allowing roots to grow laterally through the open structure while the grids reinforce and protect the surface.

Can GRASSRINGS be cut?

Yes. GRASSRINGS can be cut where required to accommodate boundaries, curves and irregular shapes. Joints can also be staggered to help minimise waste.

Do GRASSRINGS need a sub-base?

Yes. GRASSRINGS should be installed over a suitable prepared stone sub-base appropriate for the ground conditions and anticipated loading. Correct sub-base construction is important for the stability and performance of the finished surface.

Are GRASSRINGS suitable for commercial parking?

Yes. GRASSRINGS can be used for both private and commercial grass parking applications, including overflow and occasional parking areas, subject to appropriate design and installation.

GRASSRINGS Installation Information

Correct ground preparation and sub-base construction are essential to the performance of a GRASSRINGS grass reinforcement system.

The grids should be installed over a suitable prepared stone sub-base, clipped together, filled with an appropriate topsoil and growing medium and then seeded to establish the finished grass surface.

The required sub-base specification will depend on factors including existing ground conditions, drainage and the type and frequency of traffic using the completed area.
