Geotextile fabric: why it's essential for your development projects

Whether it's for a gravel driveway, a patio, a sidewalk or a flower bed, the stability of your landscaping often depends… on what you can't see.

Geotextile fabric is a key element in ensuring the durability, drainage, and stability of your outdoor projects. Yet, it is often neglected or poorly chosen.

Here is everything you need to know before starting your project.

What is a geotextile fabric?

Geotextile fabric is a permeable membrane installed between the natural soil and granular materials (gravel, crushed stone, sand, etc.).

Its main role is to:

• Separate the materials

• Stabilize the base

• Allow drainage

• Reduce weed regrowth

Unlike a simple weed barrier fabric, geotextile is designed to support a load and reinforce the soil structure.

Why use a geotextile fabric?

1. Prevents the mixing of materials

Without geotextile, the gravel gradually sinks into the ground. The soil rises, drainage becomes less efficient, and the structure loses its stability.

2. Improves drainage

The fabric allows water to pass through while maintaining the separation of the layers. The result: less water accumulation and fewer problems related to freezing and thawing.

3. Extends the lifespan of your project

A well-structured base means less maintenance, less settling, and less need to add stone over the years.

In which projects should a geotextile fabric be used?

Geotextile fabric is recommended for:

• Gravel driveway

• Parking

• Interlocking paving stone base

• Patio

• Sidewalk

• Flower bed

• Outdoor trail

In summary: as soon as there is gravel or stone on natural ground, geotextile is highly recommended.

Which geotextile fabric should I choose? Standard or SolPro PUS?

At Gauvreau Terre de Surface, we offer two types of geotextile depending on the size of your project.

Standard geotextile fabric

Ideal for:

• Flowerbeds

• Light residential projects

• Decorative pathways

• Minor renovation work

It offers excellent material separation for moderate load projects.

SolPro PUS geotextile fabric

Recommended for:

• Car entrances

• Parking

• High-traffic areas

• Projects requiring greater strength

The SolPro PUS is more robust and designed to support heavier loads. It is ideal when long-term stability is a priority.

The most common mistakes

❌ Do not compact the soil before installation
❌ Do not overlap the geotextile strips
❌ Choosing a geotextile fabric that is too light for the project 
❌ Install directly on very soft ground without preparation

A good result depends as much on soil preparation as on the choice of product.

Installation tips

1. Level and compact the natural soil

2. Unroll the geotextile fabric

3. Overlap the strips by 6 to 12 inches

4. Add the gravel or stone on top

5. Compacting granular materials

Proper installation makes all the difference to the longevity of your setup.

A small investment for a big impact

Geotextile fabric represents a small portion of the total cost of a project, but it can save a lot in maintenance and repairs in the long term.
