Landscape Fabric Under Gravel: When It Helps
Landscape fabric under gravel is a permeable sheet laid on the soil before the stone goes down. Its main job is separation: it keeps gravel from pushing into the soil and keeps soil from working up into the gravel, which helps paths, patios, and driveways stay firm and drain well. It also slows weeds growing up from below, though weeds that sprout in dust and debris on top of the gravel still appear. Choose the right fabric for the job and install it with good overlaps, and it adds years of life to a gravel surface.
Volume and tonnage calculator →Types of fabric
| Fabric | Best for |
|---|---|
| Woven geotextile | Driveways, parking pads, heavy loads |
| Nonwoven geotextile | Drainage, French drains, paths |
| Spun-bonded landscape fabric | Light-duty paths and beds |
| Perforated plastic | Generally not recommended under gravel |
Woven geotextile has high tensile strength and resists tearing under vehicle loads. Nonwoven fabric is felt-like and lets water pass easily, which suits drains. Thin landscape fabrics from garden centers work for foot traffic but can tear under driveways.
When it helps
- Soft or clay soils: fabric stops base stone from sinking into mud.
- Driveways and parking pads: separation keeps base thickness intact.
- Decorative gravel paths: limits mixing of soil and stone and slows weeds.
- French drains: nonwoven fabric keeps soil from clogging the stone.
When to skip it
On firm, well-drained soil with a thick, compacted base, fabric may add little. Under organic mulch, fabric can trap a layer of decomposing material where weeds grow anyway. In planting beds, fabric can block soil improvement.
How to install it
- Excavate and grade the area, removing roots and sharp rocks.
- Compact the subgrade if it will carry traffic.
- Roll out fabric with overlaps of about 12 inches; more on soft soil.
- Pin it with landscape staples every 3 to 5 feet and along seams.
- Run it up the sides against edging if possible.
- Place gravel by dumping onto the fabric and spreading forward, so equipment does not drive directly on bare fabric.

Gravel depth over fabric
| Project | Typical gravel over fabric |
|---|---|
| Decorative path | 2 to 3 in |
| Patio | 4 in base plus 1 to 2 in top |
| Driveway | 6 to 8 in base plus 2 in top |
Thin gravel layers let fabric show through as stone moves. Keep enough depth to cover it. The asphalt base calculator can estimate tons.
Edging
Edging holds gravel and fabric in place at the borders. See gravel driveway edging.
Maintenance
Rake gravel to cover exposed fabric, pull weeds when small, and blow off leaves before they break down into soil on top.
Bottom line
Landscape fabric under gravel separates stone from soil, keeps paths and driveways firmer, and slows weeds from below. Use woven geotextile for driveways, nonwoven for drainage, overlap seams about 12 inches, pin it well, and keep enough gravel on top to hide it.
Questions people ask
Should I put landscape fabric under gravel?
Usually yes on soft soil, paths, and driveways, to keep stone and soil separate.
What fabric is best under a gravel driveway?
Woven geotextile, which handles vehicle loads.
Does landscape fabric stop weeds in gravel?
It slows weeds from below, but seeds can still sprout on top.
How much should fabric overlap?
About 12 inches, more on soft ground.
