Mirafi 140NL Geotextile Fabric - 12.5' x 360' Roll - Solmax
FREE SHIPPING
Mirafi 140N is a workhorse nonwoven geotextile, built to separate soil layers and let water pass while holding fines back.
This needle-punched polypropylene fabric is a go-to for subsurface drainage, French drains, and under-aggregate separation, where it keeps base stone from pumping down into soft subgrade and clogging with silt. High flow-through and strong particle retention let it drain freely without losing the soil beneath.
Contractors reach for the 140-class because it balances durability and permeability at a working-grade price. It rolls out fast, conforms to uneven ground, and stands up to installation stress on driveways, roadways, drainage trenches, and erosion-control projects where long-term separation matters.

Why Choose Mirafi 140NL?
5 reasons engineers and contractors specify Mirafi N-Series over generic nonwoven geotextiles
USA-Made, BABA Eligible
Produced in Georgia, Mirafi 140NL qualifies for Build America / Buy America requirements on public projects — a compliance advantage generic imports cannot offer.
Consistent AOS Every Roll
The 140NL is engineered for reliable Apparent Opening Size (AOS) performance that keeps fine particles in place without sacrificing hydraulic conductivity — meeting AASHTO M288 filtration criteria.
Needle-Punched Uniformity
Unlike heat-bonded or spunbond-only fabrics, Mirafi's needle-punched polypropylene creates a consistent three-dimensional fiber matrix that resists soil piping and maintains long-term filtration without clogging.
40+ Years of Infrastructure Reliability
TenCate Mirafi has been a trusted geotextile standard on civil and transportation projects for over four decades. That institutional knowledge and field data simply doesn't exist for generic alternatives.
Pre-Approved on State DOT QPLs
Mirafi N-Series fabrics appear on DOT Qualified Products Lists across the country. Using a pre-approved Mirafi product eliminates the uncertainty of spec substitution reviews.
