Which Geotextile Membrane Do I Need? A Straightforward Guide

If you’re starting a landscaping, groundwork or equestrian project, there’s a good chance you’ve been told you’ll need a geotextile membrane. But knowing which one to choose - and why - can be less obvious.

Here’s a clear, no-nonsense guide to help you pick the right type for the job, based entirely on what you're building.

For Driveways, Paths and Patios

If you’re laying a sub-base and want to stop the layers mixing, you’ll need a non-woven geotextile membrane. These act as a separation and filtration layer. They’re most often used under:

• Gravel or stone driveways
• Patios and paths
• Artificial grass installs
• Trench lining and French drains

A lightweight non-woven roll is ideal for most domestic jobs and prevents sub-base loss over time.

Recommended product:
NW8 Non-Woven Membrane

For Heavier Loads or Soft Ground

When you’re dealing with unstable ground or heavy traffic, go for a woven geotextile membrane. These offer higher tensile strength and are designed to reinforce the ground.

• Access roads or farm tracks
• Car parks and lorry turning areas
• Paddocks and gateways
• Any surface prone to rutting or sinking

Recommended product:
G90 Woven Membrane

For Horse Arenas and Manèges

For any horse arena build, you’ll usually need a combination of both woven and non-woven membranes to get the right performance.

• A non-woven layer for drainage and separation
• A woven layer for strength and stability
• Jointing tape to secure overlaps
• Optional EcoGrid paving for added structure

For Soakaways and Drainage Projects

If you’re wrapping a crate or lining a trench, use a non-woven geotextile membrane that allows water to pass through while keeping soil out. This maintains proper drainage and reduces maintenance over time.

Securing It All in Place

To get a reliable result, use the correct installation accessories:

• Single sided jointing tape - for joining overlaps
• Barbed fixing pegs - to prevent movement
• Bay markers - useful for surface layout

All are compatible with ETC geotextile membranes and designed for fast, secure installation.
