GRAVELRINGS Black 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 gravel driveways, parking areas, paths and vehicle access routes without the common problems of gravel migration, rutting and uneven coverage. This pack contains four black 500mm x 500mm gravel grids, providing a total coverage of 1m².

Manufactured from 100% recycled, UV-stabilised HDPE, GRAVELRINGS provides a strong and durable base for loose aggregate while maintaining a permeable surface suitable for incorporation into SuDS compliant schemes.

Each 25mm deep panel features a series of circular gravel retention cells with an integral mesh backing grid. This design helps keep loose aggregate securely in position while allowing water, silts and fines to pass through the system.

When correctly installed over a suitable stone sub-base and filled with the specified angular aggregate, GRAVELRINGS provides a stated load-bearing capacity in excess of 350 tonnes per m².

What Are GRAVELRINGS Used For?

GRAVELRINGS can be used anywhere a stable, load-bearing gravel surface is required while maintaining permeability and the appearance of loose aggregate.

Typical applications include:

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

Are GRAVELRINGS Suitable for Gravel Driveways?

Yes. GRAVELRINGS are specifically designed for stabilising loose aggregate on gravel driveways and other trafficked surfaces.

Without a gravel retention system, repeated vehicle movement can push loose stone away from wheel tracks, resulting in deep ruts, exposed sub-base and inconsistent gravel coverage.

GRAVELRINGS retain the aggregate inside individual 50mm diameter circular cells, helping restrict lateral movement and distribute the gravel more evenly across the driveway.

When correctly installed and covered with the specified depth of gravel, the black grid remains hidden beneath the finished surface.

How Do GRAVELRINGS Stop Gravel Moving?

GRAVELRINGS use two key features to help stabilise loose gravel.

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

An integral mesh backing grid beneath the cells prevents gravel from gradually working underneath the panels. This is important because loose aggregate beneath a grid can undermine the panels and lead to an uneven finished surface.

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

Are GRAVELRINGS Permeable?

Yes. GRAVELRINGS are designed to create a fully permeable gravel surface.

Rainwater can pass through the gravel, grid and underlying construction rather than being forced to run off a conventional impermeable surface.

This makes GRAVELRINGS suitable for incorporation into appropriately designed Sustainable Drainage Systems (SuDS).

The SuDS compliance and drainage performance of the finished project will depend on the complete installation, including the sub-base, existing 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 one pack covers 1m²:

15m² = 15 packs of GRAVELRINGS

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

What Size Gravel Should I Use with GRAVELRINGS?

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

Angular gravel is recommended because the individual pieces interlock with one another, helping to create a stable surface within the gravel retention cells.

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

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

How Much Gravel Do I Need for GRAVELRINGS?

The recommended gravel requirement is approximately:

58 to 67kg per m²

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

The exact amount required will depend on the density and grading of the chosen aggregate.

Example Gravel Calculation

For a 20m² driveway:

20m² x 58kg = 1,160kg

to

20m² x 67kg = 1,340kg

You would therefore require approximately 1.16 to 1.34 tonnes of gravel, subject to the density and grading of the chosen aggregate.

How Strong Are GRAVELRINGS?

GRAVELRINGS have a stated load-bearing capacity in excess of 350 tonnes per m² when correctly installed and filled with suitable 6mm to 20mm angular gravel.

For this stated capacity, the aggregate should extend approximately 15mm above the top of the GRAVELRINGS cells.

The circular design provides excellent structural integrity and helps distribute loads across the completed gravel surface.

Overall performance will also depend on correct ground preparation, sub-base construction and installation.

What Is the GRAVELRINGS Mesh Base For?

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

The mesh helps prevent loose aggregate from migrating underneath the panels, where it could gradually undermine the grid and affect the stability of the finished driveway or path.

At the same time, the open structure allows water, silts and other fines to pass through, maintaining the permeability of the system.

Can GRAVELRINGS Help Reduce Weed Growth?

The GRAVELRINGS grid design helps resist the build-up of silt and fines, reducing some of the conditions that can encourage weeds to establish within a gravel surface.

However, no outdoor gravel surface can be guaranteed to remain completely weed-free. Seeds and organic material can accumulate on the surface over time, so occasional maintenance may still be required.

Can GRAVELRINGS Be Installed on a Slope?

GRAVELRINGS can be installed on suitable gradients, but the maximum appropriate slope depends on factors including the gradient itself, expected vehicle traffic, ground conditions and sub-base construction.

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

GRAVELRINGS Installation Information

Correct ground preparation and sub-base construction are essential to the performance of a GRAVELRINGS gravel retention system.

The panels should be installed over a suitable prepared stone sub-base, clipped together and filled with 6mm to 20mm angular quarried aggregate.

The finished aggregate level should extend approximately 15mm above the top of the cells.

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