01 DuPont GroundGrid

A Geotextile Grid For Ground Stabilization

DuPont GroundGrid is a ground stabilization grid built from high-performance geotextile rather than rigid plastic. Panels ship compact, expand into a three-dimensional honeycomb on site, and are then filled with angular stone to produce a strong, stable surface where bare gravel would rut and wash out.

The confinement is what does the work. Filled cells lock the aggregate in place so it cannot migrate laterally, which is what turns loose stone into an even, load-bearing surface and keeps it that way through weather and traffic. The structure also lets water move horizontally through the grid rather than damming up alongside a pathway, so drainage improves instead of being interrupted. The fabric construction keeps it lightweight and flexible enough to follow ground contours, and easy enough to place without specialist plant.

Infill matters: GroundGrid must be used with 3/4″ angular stone. Do not use pea gravel as an infill. Rounded gravel shifts within the cells and will not lock up, and fines clog the permeability that makes the system drain.

108square feet per panel — 4′ × 25′

Expanded panels measure about 4.1′ × 26.3′, at a 2″ cell depth.

02 Why it works

Confined Stone Behaves Like Pavement

Loose aggregate fails because individual stones can move. Once each stone is confined in a cell, the surface distributes weight rather than displacing under it — so a driveway stops forming ruts at the wheel tracks and a path stops migrating toward its edges. Because the grid is permeable, rainfall still infiltrates instead of running off, which is what makes it an alternative to paving on sites where runoff is a concern.

03 Choose a grid

Small Grid Or Large Grid

The two versions are not interchangeable, and picking the wrong one will not perform. Cell size is the whole difference — and it decides what the panel may be used for.

Important: the manufacturer recommends the small grid for stabilizing driveways and walkways, because the smaller cell increases stability and reduces gravel and soil migration. The Large Grid (DPGG-50110) is not to be used on any ground stabilization application — it is a pond edge product.

04 Small grid

Ground Stabilization Applications

Anywhere a gravel surface has to carry traffic without rutting.

Residential driveways Parking lots Overflow parking Walkways & paths Fire lanes Emergency access roads Construction entrances Equipment & truck yards Wash-down areas RV & boat access Road shoulders Building sites

05 Large grid

Pond Edge Applications

The large grid exists for one job: retaining material along a pond edge, where the wider cell suits the placement and there is no traffic load to resist. Its heavier 8.5 oz fabric reflects the exposure rather than a higher load rating.

  • Pond and water feature edges — the intended application.
  • Not for driveways, walkways or parking. Use the small grid for any trafficked surface.
  • Not for ground stabilization of any kind, per the manufacturer.
Building a driveway or path? Order the small grid (DPGG-5055) instead.

06 Installation

Four Steps To A Stable Surface

  1. Prepare the base. Excavate and compact the subgrade to suit the load. Where the ground below is soft, lay a landscape fabric first — it stops weed growth and keeps aggregate from being pushed down into the soil beneath the grid.
  2. Expand and anchor. Pull the panel open to its full honeycomb form and anchor the corners with stakes or landscape pins so it holds its geometry.
  3. Connect and fill. Butt panels edge to edge across the area, then fill the cells with 3/4″ angular stone and compact.
  4. Finish flush. Add a thin top layer of stone so the cell tops are covered and the surface is even — that is what spreads load across the whole panel rather than into individual cells.

Measurements in the installation video are metric.

The video shows a ground stabilization application. Only the small grid is recommended for that use.

07 Underneath the grid

Fabric Below The Grid

If the ground below the installation area is soft, a landscape fabric is recommended underneath the grid. It does two jobs: it blocks weed growth coming up through the surface, and it stops aggregate being pushed down into the soil below, which is how a stabilized surface slowly loses the stone that makes it work.

08 Keeping it right

Maintenance

  • Top up the aggregate occasionally where it gets displaced, typically at entry points and turning areas.
  • Check the edges and anchors annually and re-secure anything that has shifted.
  • Rake walkway surfaces periodically for an even texture.
  • Keep the cell tops covered — exposed fabric wears faster than covered fabric.

11 Common questions

GroundGrid FAQs

Which grid do I need?
The small grid (DPGG-5055) for any ground stabilization work — driveways, walkways, parking, access roads. Its smaller cell increases stability and reduces gravel and soil migration. The large grid (DPGG-50110) is a pond edge product and is not to be used on ground stabilization applications.
What infill should I use?
3/4″ angular stone. Do not use pea gravel — rounded stone shifts within the cells instead of locking up, and fine material clogs the permeability that lets the surface drain.
How much area does a panel cover?
108 square feet. The panel is sold as 4′ × 25′ and expands to about 4.1′ × 26.3′, at a 2″ cell depth.
Do I need fabric underneath?
If the ground below is soft, yes. A landscape fabric under the grid blocks weed growth and keeps aggregate from being pushed down into the soil below, which is how a stabilized surface gradually loses the stone that makes it perform.
How is this different from a plastic geocell?
The cells are formed from welded geotextile fabric strips rather than rigid plastic sheet, which makes the panel lightweight and flexible enough to follow ground contours, and simple to place by hand. It also allows water to flow horizontally through the structure rather than damming alongside the pathway.
Will it handle vehicles?
The small grid is intended for trafficked surfaces including driveways, parking areas, fire lanes and equipment yards. As with any stabilized surface, the compacted base under the grid matters as much as the grid itself — build the base to suit the heaviest vehicle using the area.
How do I maintain it?
Top up aggregate where it gets displaced, usually at entry points and turning areas; check edges and anchor points annually and re-secure anything that has moved; and rake walkway surfaces occasionally for an even texture. Keep the cell tops covered with stone.
How much does shipping cost?
Shipping is free on every order at Landscape Discount — panels ship free with no minimum order.
