TNW2000 White Non-Woven Geotextile Membrane 200gsm

This product is a white, non woven, permeable geotextile membrane manufactured from UV stabilised polypropylene staple fibres using a needle punched process. At 200gsm, TNW2000 offers high tensile strength and puncture resistance, making it suitable for heavy duty separation and filtration applications.

In the ground, the membrane allows water to pass freely through the fabric while preventing fine soils from migrating into clean aggregate layers. This helps maintain drainage performance, protects the integrity of the sub base and reduces long term settlement caused by contamination of the stone layer.

TNW2000 is commonly specified beneath driveways, access roads, car parks and hardstanding where regular vehicle traffic is expected. It is also used as a robust filtration layer in French drains, soakaways and attenuation systems, particularly where the sub grade is weak, clay based or variable.

This grade is well suited to installations where lower weight membranes may be damaged during construction or compromised by sharp aggregates. The combination of tensile strength and elongation allows the membrane to flex under load while resisting puncture and tearing.

Install TNW2000 on a prepared sub grade free from sharp protrusions. Overlap adjacent sheets by at least 300mm, increasing to 500mm on soft or uneven ground. The membrane should be covered promptly with aggregate to prevent damage during installation.

• Heavy duty non woven geotextile for separation and filtration
• High puncture resistance for trafficked and poor ground conditions
• Allows water flow while retaining fine soils
• Suitable for driveways, car parks and access roads
• Performs well on clay or variable sub grades
• Supplied in a full width roll for efficient coverage

Manufactured from UV stabilised polypropylene staple fibres using a needle punched construction. This provides a permeable membrane with high mechanical strength and resistance to installation damage.
