TNW1500 White Non-Woven Geotextile Membrane 160gsm

This product is a white, non woven, permeable geotextile membrane manufactured from UV stabilised polypropylene staple fibres using a needle punched process. At 160gsm, TNW1500 offers a significant increase in tensile strength and puncture resistance compared to lighter grades, making it suitable for more demanding groundworks and trafficked applications.

In use, the membrane allows water to pass freely through the fabric while preventing fine soils from migrating into clean aggregate layers. This separation function helps maintain drainage performance, reduces sub base contamination and limits long term settlement caused by fines pumping into the stone layer.

TNW1500 is commonly specified beneath domestic driveways, access roads, hardstanding and light commercial areas where vehicle traffic is expected. It is also used as a robust filtration layer in French drains, soakaways and granular drainage blankets, particularly where ground conditions are variable or installation stresses are higher.

This grade is well suited to sub grades with moderate bearing capacity where lighter membranes may be at risk of damage during construction. It provides a reliable balance of flexibility and strength, allowing it to accommodate stress and strain during aggregate placement while resisting puncture.

Installation should be carried out on a prepared sub grade free from sharp objects. Overlap adjacent sheets by a minimum of 300mm, increasing to 500mm on soft or uneven ground. Cover the membrane promptly with aggregate to protect it during construction.

• Medium to heavy duty non woven geotextile for separation and filtration
• Higher tensile strength for trafficked and load bearing areas
• Resists puncture during installation and aggregate placement
• Allows water flow while retaining soil and fine particles
• Suitable for driveways, access roads and drainage systems
• Supplied in a full width roll for efficient site coverage

Manufactured from UV stabilised polypropylene staple fibres using a needle punched construction. This produces a permeable, flexible membrane with increased mechanical strength for more demanding ground conditions.
