Installation Instructions

For Loose Gravel Top Installation

1) Lay out job prior to excavation.

2) Remove all vegetation, debris or pavement.

3) Excavate soil to appropriate depth (see chart below)

4) Prep subgrade. Use gravel to level any areas if desired.

5) Install non-woven geotextile fabric overlapping by a minimum of 12" at the seams.

6) Lay out stakes.
- 4 stakes should be placed at each corner of expanded Grid dimensions.
- You should have 1 stake in each corner.

NOTE: Grid can be cut with any cutting tool to any shape or size as needed to fit the job site.

7) Unpack Grid.
- Remove bands with any cutting tool.
- Unfold the Grid.

NOTE: If using more than one piece of Grid refer to connection instructions below.

8) Expand Load Support Grid past each stake to uniformly expand all cells and then relax the Grid allowing corner cells to be placed over installed stakes. Add additional stakes as necessary.

9) Continue to add stakes or simply fill gravel in perimeter cells as needed to ensure proper expansion.

10) Install rebar j-hooks every 4' to keep the grid pinned down.

11) Begin filling cells with infill (see chart below for specified material).
- To prevent damage to the Grid, limit the drop height of infill to no more than 3 ft.

12) Machine infill. 
- It is safe to drive on cells that have been completely filled.


13) Rake or blade compact the infill to specified dimensions over top of cells (see chart below for dimensions).

14) Compact infill with a plate compactor or plate tamper.

COMPLETED: Gravel-Tek installation.

For Grassy Top Installation

Instead of a non-woven geotextile fabric, use Triax geogrid as the underlayment below the cells. This will allow grass roots to grow deep.

Instead of filling the cells with stones, fill with a 50%/50% mix of washed angular stones and topsoil.


COMPLETED: Grass-Tek Installation

For Paver Top Installation

- Traditional Method: Screed sand and lay pavers.

- Permeable Method: Lay permeable pavers.

Note: Rebar j-hooks as shown above are not necessary for this application.

COMPLETED: Paver-Tek Installation

*After compaction, infill settles to about 1/2" above cell
