SNW80 White Non-Woven Geotextile Membrane 650gsm

SNW80 is a superior grade needle-punched non woven geotextile membrane manufactured from polypropylene fibres. At 650gsm, it sits well above standard non woven membranes in both strength and puncture resistance, making it suitable for demanding ground conditions and high load applications.

Unlike thermally bonded membranes, SNW80 is needle punched only. This construction gives the fabric high elongation and toughness, allowing it to flex under load while resisting tearing and puncture. This makes it particularly well suited to installations where sharp aggregates, trafficking during construction or repeated loading are expected.

In the ground, SNW80 provides effective separation by preventing the migration of fines into clean aggregate layers, while still allowing water to pass through the fabric. This helps maintain bearing capacity and drainage performance over time, especially in applications where ground failure would be costly or disruptive.

SNW80 is widely used in equestrian applications such as horse arenas, paddocks and turnout areas, where high point loads and constant movement place extreme stress on the ground build up. It is also specified beneath driveways, access roads and hardstanding, as well as for trench lining, French drains and as a protection layer around soakaway crates and attenuation tanks.

This membrane is not intended as a lightweight landscaping fabric. Its primary role is reinforcement, protection and long term stability in high stress environments. For lighter duty separation, a lower gsm non woven membrane should be selected.

Install SNW80 on a prepared sub grade free from sharp protrusions. Overlap adjacent rolls by at least 300mm, increasing on soft or uneven ground. Cover promptly with aggregate to protect the membrane during construction.

• Very heavy duty non woven geotextile for high load applications
• Needle-punched construction for strength and flexibility
• High puncture resistance for use with sharp aggregates
• Suitable for equestrian, road and driveway construction
• Performs as separation, filtration and protection layer
• Large format roll for efficient coverage on site
