GRAVELRINGS White Gravel Retention System – 25mm x 500mm x 500mm – Pack of 4 (1m²)

GRAVELRINGS is a heavy-duty, fully permeable gravel retention system designed to create stable and attractive gravel driveways, paths, parking areas and access routes without the common problems of loose stone migration, rutting and inconsistent gravel coverage. This pack contains four white 500mm x 500mm gravel grids, providing a total coverage of 1m².

Manufactured from UV-stabilised HDPE incorporating recycled material, each GRAVELRINGS panel features strong circular cells combined with an integral mesh backing grid. The 25mm deep system holds loose aggregate securely in position while allowing water, silts and fines to pass through the surface.

When correctly installed over a suitable stone sub-base and filled with the specified angular aggregate, GRAVELRINGS can provide a load-bearing capacity in excess of 350 tonnes per m², making the system suitable for a wide variety of residential and commercial applications.

Its fully permeable construction also makes GRAVELRINGS suitable for use as part of SuDS compliant schemes, subject to the design and construction of the complete installation.

What Are GRAVELRINGS Used For?

GRAVELRINGS can be used for a wide variety of applications where the appearance and permeability of loose gravel are wanted without the instability normally associated with an unrestrained gravel surface.

Typical applications include:

• Gravel driveways
• Residential parking areas
• Commercial parking
• Gravel paths
• Garden paths
• Vehicle access routes
• Overflow parking
• Caravan and motorhome parking areas
• Holiday parks
• Campsites
• Landscaping projects
• Courtyards
• Garden areas
• Commercial developments
• Permeable paving schemes
• SuDS drainage projects

Are GRAVELRINGS Suitable for Gravel Driveways?

Yes. GRAVELRINGS are specifically designed to stabilise loose aggregate on gravel driveways and other trafficked surfaces.

Traditional loose gravel driveways can develop problems such as wheel ruts, displaced stone and areas of inconsistent coverage as vehicles repeatedly travel across the surface.

GRAVELRINGS hold the aggregate within individual 50mm diameter circular cells, helping prevent lateral movement and keeping the gravel distributed more evenly across the driveway.

When correctly installed and filled, the grids remain hidden beneath the finished gravel surface.

How Do GRAVELRINGS Stop Gravel Moving?

GRAVELRINGS use a combination of circular retention cells and an integral mesh backing grid.

The circular cells restrict the lateral movement of loose aggregate as vehicles and pedestrians move across the surface.

The integral backing grid also prevents gravel from gradually working underneath the panels. Without a suitable backing system, aggregate moving underneath a gravel grid can undermine the panels and affect the stability and appearance of the finished surface.

The GRAVELRINGS backing remains open enough to allow water, silts and other fines to pass through the system.

Are GRAVELRINGS Permeable?

Yes. GRAVELRINGS are designed as a fully permeable gravel retention system.

Rainwater can pass through the loose aggregate and open grid construction into the layers below, subject to the permeability and drainage characteristics of the complete installation.

This allows GRAVELRINGS to be incorporated into appropriately designed Sustainable Drainage Systems (SuDS) where permeable surfacing is required.

The overall drainage performance and SuDS compliance of a project depend on the complete surface and sub-base construction, ground conditions and drainage design.

How Much Area Does One Pack of GRAVELRINGS Cover?

Each GRAVELRINGS panel measures:

500mm x 500mm x 25mm

A single panel covers:

0.5m x 0.5m = 0.25m²

Each pack contains four panels:

4 x 0.25m² = 1m²

You therefore need approximately one pack of four GRAVELRINGS for every 1m² of area before allowing for cuts and wastage.

Example GRAVELRINGS Quantity Calculation

For a driveway measuring 5 metres long by 3 metres wide:

5m x 3m = 15m²

As each pack covers 1m²:

15m² = 15 packs of GRAVELRINGS

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

What Size Gravel Should I Use with GRAVELRINGS?

GRAVELRINGS should be filled using 6mm to 20mm angular quarried aggregate.

Angular gravel is important because the individual pieces interlock with one another, helping create a stable finished surface within the retention grid.

Marine-washed, rounded and mixed aggregates should not be used.

Rounded gravel does not interlock in the same way as angular quarried stone and may therefore compromise the stability and intended performance of the completed system.

How Much Gravel Do I Need for GRAVELRINGS?

The approximate gravel requirement is:

58 to 67kg of gravel per m²

The system should be filled with suitable 6mm to 20mm angular quarried aggregate, with the gravel extending approximately 15mm above the top of the GRAVELRINGS cells.

The precise amount of gravel required will vary depending on the density and grading of the chosen aggregate.

For example, a 20m² driveway would require approximately:

20 x 58kg = 1,160kg

to

20 x 67kg = 1,340kg

This equates to approximately 1.16 to 1.34 tonnes of gravel, subject to the characteristics of the chosen aggregate and site conditions.

How Strong Are GRAVELRINGS?

GRAVELRINGS provide a stated load-bearing capacity in excess of 350 tonnes per m² when correctly installed and filled with suitable 6mm to 20mm angular gravel to approximately 15mm above the top of the cells.

The circular grid design provides high structural integrity while distributing loads across the completed surface.

Actual performance depends on the complete installation, including ground preparation, sub-base construction and the type and depth of aggregate used.

What Is the Integral Mesh Base For?

Each GRAVELRINGS panel incorporates a mesh backing grid beneath the circular cells.

This performs two important functions.

Firstly, it helps prevent gravel from migrating underneath the panel, where it could gradually undermine the grid and create an uneven surface.

Secondly, the open mesh construction allows water, silts and other fines to pass through, maintaining the permeability of the system and helping resist the build-up of material within the cells.

Can GRAVELRINGS Help Prevent Weeds?

The GRAVELRINGS design helps resist silt build-up, which can reduce the conditions that encourage weed growth within a gravel surface.

However, no external gravel surface can be guaranteed to remain completely weed-free. Airborne seeds and organic matter can accumulate on virtually any outdoor surface over time, so occasional maintenance may still be required.

Can GRAVELRINGS Be Installed on a Slope?

GRAVELRINGS can be installed on suitable sloping or gradient applications, but suitability depends on the gradient, anticipated traffic, sub-base construction and other site-specific conditions.

For installations on a significant slope, please contact our sales team for advice before ordering.

GRAVELRINGS Installation Information

Correct ground preparation and sub-base construction are essential to achieving a stable, permeable GRAVELRINGS surface.

The grids should be installed over a suitable prepared stone sub-base, clipped together and filled using 6mm to 20mm angular quarried aggregate. The finished gravel should extend approximately 15mm above the top of the grid cells.

The required sub-base specification will depend on existing ground conditions, drainage requirements and the type and frequency of traffic expected to use the completed surface.
