COREgravel Install Guide

1. BASE PREPARATION.

For base preparation, level and clear the area, then excavate and compact allowing for grid thickness and an additional 10mm surface dressing of aggregate.

2. PLACE THE PANELS.

Position the panels on the prepared base with geotextile face down. Cut to shape with pruning shears or a utility knife. Use protective gloves to avoid abrasions. Top of hexagon cell panels should be 10mm below adjacent hard surfaced pavements or final grade. Place first row of panels against a stationary edge if possible. Stagger panels in a bricklayer pattern.

The panels have interlocking connectors, however most installations do not require them to be used. Only in areas with greater traffic or steeper grade are they used to lock one direction or both directions. No anchors are needed for gravel stabilizer panels since the geotextile backing prevents any push up.

3. FILL THE CELLS.

Infill gravel or aggregate into the hexagon cells by hand, or directly from a truck. Trucks should be careful to avoid sharp turns on unfilled panels. Preferably the truck should dump gravel first on the edge of the installation area, then work inward, therefore only driving on filled cells. Gravel can be spread by hand with flat shovels, asphalt or tarmac rakes, blades, or stiff brooms. A power broom may spread the gravel faster.

4. SMOOTH SURFACE.

Level gravel or aggregate to cover COREgravel gravel stabiliser panels by 1 cm (0.4 inches) so the panels are just out of sight. This allows for aesthetics, stability and protection. Optionally, a vibratory plate, compactor, or roller can be used to set the gravel into the cells.
