Gravelrings panels are designed to effectively contain and stabilise loose aggregate surfacing, preventing gravel migration, sinking and rutting and making it possible to walk, cycle and push small-wheeled vehicles, such as wheelchairs and pushchairs, over the surface. The unique design of this gravel retention grid includes an open mesh base that allows water to pass through whilst preventing the build-up of silt and fine debris within the cell. This prevents the aggregate working its way beneath the grid, causing it to lift and making it very difficult to rectify.
Installing gravel retention panels
Here’s a step-by-step guide to installing the Gravelrings system.
Step 1. Excavate soil (sub-grade) to the required depth (allowing for sufficient depth of sub-base material and the panels / surface finish).
Step 2. Lay DRAINTEX or DRIVETEX geotextile fabric as per instructions for relevant product (to find out which geo textile fabric is best for your application see our Geo Fabric Product Selector).
Step 3. Secure using EXTRAFIX fixing pegs.
Step 4. Lay stone sub-base layer (e.g. MOT Type 1 or 3 – Type 3 must be used for porous installations) to the required depth, compact and level to engineer’s specification.
Step 5. Blind the surface with a layer of sharp sand or granite fines to level out any undulations in the sub-base before laying the panels.
Step 6. Lay the Gravelrings Gravel panels over the base with the mesh side down and clip together. Fix down using Gravelrings Fixing Pins (if required). It is recommended that fixing pins are used on slopes, edges, turning circles, cross-overs and any areas more exposed to regular traffic. The number of pins required will depend on the application and site conditions but as a guide allow 1 pin per panel (4 per m²).
Step 7. Leave a gap (min 50mm) when adjoining a kerb or any other type of fixed edging, obstruction or structure, to allow for expansion of the panels.
Step 8. Spread the final gravel surface over the panels to a depth of approx 10-15mm higher than the top edge of the rings, so that they are concealed.
Step 9. Rinse the gravel with water (if required) and lightly compact the gravel to aid settlement and consolidation.
