Where Should It Be Installed?

Primary Layer (Recommended)
Install directly over prepared soil after excavation and before sub-base installation.

Secondary Layer (Optional)
Can also be installed between sub-base and artificial grass for additional weed control.

For most installations, one properly installed base layer is sufficient.

How to Order

This membrane is supplied 4.5m wide as standard.

Simply select the required length and you will receive:

Example:
Your chosen length X 4.5m width
Therefore ordering 10m long will provide 45m² coverage.

How Much Should I Order?

When calculating requirements, allow for:

  • Minimum 200mm overlap
  • Edge trimming
  • Small cutting allowance

We recommend ordering approximately 10% extra.

Installation Tips

  • Roll out flat without stretching
  • Overlap joins by at least 200mm
  • Secure using U-Pins or Weed Membrane Pegs
  • Ensure full ground coverage before adding sub-base

Proper installation improves long-term performance and reduces weed breakthrough risk.

When Should I Choose 100gsm Over 70gsm?

Choose 100gsm if:

  • You want extra durability and stability
  • The ground is uneven or rough
  • You are installing on larger areas
  • You prefer fewer joins
  • You want a more premium base layer

For standard domestic installs, 70gsm is typically sufficient. For added strength and longevity, 100gsm is recommended.
