GravelGrid

The special surfacing grid.

For fire service access roads, service yards, embankments and to provide grip on inclines.

• Prevents tyre marks
• Stops gravel from spreading
• Fast installation
• Long-term water permeability

Produkt details

The special connection system and built-in overlap allow the ections to interlock and prevent displacement caused by temperature changes. The sections can only be laid in an interlocking arrangement, thus maximising the stability of the surface. The sections can be supplied with or without moulded ground spikes depending on the purpose for which they are used. An installation bed of approx. 3-4 cm is required if using ground spikes. The recesses on the underside allow an almost unimpeded flow of rainfall over the entire surface.

Installation

Beginning with the first row, connect the sections at the short ends. It is advisable to lay a batter board to aid alignment and to keep the row in position.

Then start the second row with a half section and continue fitting half sections in an interlocking arrangement. The third row can be started with a whole section and then the next row will start with a half section again, and so on.

Despite the porosity of the material, the infill cannot migrate down through the grid. The grid cannot flush out its contents.
