Class 3 Geotextile Fabric - Nonwoven
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.
The Mirafi 140N is a class 3 geotextile fabric for surface drainage applications. This non-woven fabric is designed to allow for both water flow and dimensional stability. The fabric is both rot and mildew resistant and is designed for permanent commercial installations.
The definition of a “class 3 geotextile” can vary slightly depending on the municipality, DOT or project engineer. Be sure to refer to the specification sheet below to ensure that this fabric meets the specific definition of a class 3 geotextile for your project.
Please refer to the chart below and specification sheet for additional pertaining to this fabric and its AASHTO M288 classification.
