Mirafi 140N Geotextile Filter Fabric

In the realm of geotechnical engineering, the choice of geotextile materials plays a pivotal role in ensuring the longevity and efficacy of civil engineering projects. Among these, Mirafi 140N Geotextile Filter Fabric stands out for its remarkable performance and versatility. This article delves into the key aspects of Mirafi 140N, shedding light on its composition, applications, benefits, and significance in various construction contexts.

What is Mirafi 140N Geotextile Filter Fabric?

Mirafi 140N is a nonwoven, needle-punched geotextile fabric made from 100% polypropylene staple fibers, manufactured by TenCate for use in civil and environmental engineering projects. It offers several key advantages:

• Excellent filtration and drainage – with a high permittivity (~1.7 s⁻¹) and flow rate (~135 gal/min/ft²), it allows water to pass through while retaining soil particles;
• High strength and durability – featuring a typical grab tensile strength of about 120 lbs and a CBR puncture strength of around 310 lbs, it performs well under installation and site stresses;
• Chemical and UV resistance – stable across a wide pH range and retains over 70% strength after 500 hours of UV exposure, making it suitable for harsh environments;
• Versatile applications – commonly used in roadway separation, French drains, erosion control, embankments, and landfill protection.

Mirafi 140N meets AASHTO M288 Class 3 specifications and is available in rolls typically 12.5 to 15 feet wide and up to 360 feet long.
