White NW6 Non-Woven Geotextile Fleece 80gsm

Lightweight Geotextile Membrane For Separation & Filtration

NW6 is a white non-woven geotextile fleece, designed for domestic and light trade use. With a weight of 80gsm, it’s ideal for separating soil layers, wrapping soakaways, lining French drains, and use beneath driveways and porous paving systems.

Practical Benefits

This membrane provides effective separation and filtration while allowing water to pass through, making it suitable for a range of groundwork and drainage projects:

• Allows water to drain naturally through the ground

• Prevents soil mixing between layers (e.g. sub-base and sub-grade)

• Ideal under gravel, EcoGrid, or block paving

• Compatible with attenuation tanks and soakaway crates

• Equivalent to Terram Advantage

Common Applications

• French drains and trench lining

• Soakaway and attenuation tank wrapping

• Porous paving and driveway underlay

• Weed suppression

FAQs

Is this membrane suitable for wrapping soakaway crates?

Yes, NW6 is ideal for wrapping around attenuation tanks and soakaway crates. It allows water to enter the system while keeping soil and debris out.

Can NW6 be used under gravel driveways?

Absolutely. It acts as a separator between sub-base and ground while allowing water drainage, preventing sinking or rutting over time.

What’s the difference between NW6 and heavier grades?

NW6 is a lighter membrane, suited to domestic and light-duty jobs. Heavier grades (like NW8 or NW18) offer higher strength for areas with regular traffic or where extra protection is needed.

Does the membrane suppress weeds?

Yes, it helps to reduce weed growth while still allowing water to pass through. For landscaping, it provides a durable, permeable barrier beneath gravel or soil.

How should I install it?

Unroll directly over a prepared sub-surface. Overlap adjacent sheets by at least 300mm (600mm on soft ground). Avoid stretching. Secure with pegs if needed before backfilling.
