Why Use Weed Membrane Under Artificial Grass?

Installing weed membrane beneath your artificial lawn helps:

• Suppress unwanted weed growth
• Improve long-term lawn stability
• Separate soil from sub-base
• Maintain clean drainage
• Reduce maintenance over time

While artificial grass itself blocks most light, a quality membrane adds an extra protective layer beneath your installation.

Product Specification

• Size: 15m x 1m (15m² coverage)
• Weight: 70gsm
• Type: Non-woven
• Permeable: Yes (allows water drainage)
• Suitable for: Artificial grass installations, borders & landscaping

This membrane allows rainwater to pass through freely while restricting weed penetration from below.

Where Should Weed Membrane Be Installed?

Layer 1 – Directly Over Soil (Recommended)

Place directly onto the excavated ground before installing your sub-base. This creates a barrier between soil and aggregate.

Layer 2 – Between Sub-Base and Artificial Grass (Optional)

Some installers choose to add a secondary layer beneath the grass for additional weed suppression.

For most domestic installations, one layer over the soil is sufficient.

How Much Weed Membrane Do I Need?

When installing, allow for:

• Minimum 200mm overlap at all joins
• Edges to be fully covered
• Slight trimming allowance

We recommend purchasing approximately 10% extra to allow for overlaps and cuts.

Example:
If installing 50m² of artificial grass, purchase approximately 55m² of membrane.

Installation Tips

• Roll out membrane flat and tension it gently
• Overlap joins by at least 200mm
• Secure using Artificial Grass U-Pins or Weed Membrane Pegs
• Avoid stretching excessively
• Trim neatly around edges

Correct installation ensures long-term performance and clean separation between soil and sub-base.

Is 70gsm Strong Enough?

Yes. 70gsm non-woven membrane is ideal for standard domestic artificial grass installations.

For heavy-duty or trade projects, a thicker membrane may be preferred.
