Class 2 Geotextile Fabric - Nonwoven
FREE SHIPPING
Mirafi 160N is a mid-weight nonwoven geotextile trusted for separation, drainage, and moderate stabilization.
This needle-punched polypropylene fabric keeps aggregate from mixing into soft subgrade while draining water and filtering out fines. It is widely specified for subsurface drainage, riprap bedding, and roadway separation where moderate survivability is required.
160N hits a sweet spot between strength and permeability, which is why it appears across so many DOT and commercial specifications. It installs cleanly over uneven ground and holds up to the stresses of aggregate placement.
The Mirafi 160N is a class 2 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 2 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 2 geotextile for your project.
Please refer to the chart below and specification sheet for additional pertaining to this fabric and its AASHTO M288 classification.

Why Specify Mirafi by Name?
5 reasons to specify Mirafi fabric by product name rather than by class designation alone
Named Product Provides Documented, Verifiable Performance
Specifying a class requirement alone allows substitution with any fabric claiming to meet that class — with no guarantee the substitution has third-party ASTM-verified data.
Mirafi Meets Class Requirements with Published ASTM Data
Every Mirafi geotextile has published and verifiable ASTM test values for grab tensile, AOS, permittivity, and UV resistance — backed by ISO-certified manufacturing.
USA-Made, BABA Eligible
Mirafi geotextiles are manufactured in Georgia — qualifying for Build America / Buy America requirements on federally funded projects.
40+ Years on DOT & Infrastructure Projects
A class designation does not carry a project history. Mirafi does — decades of performance on state DOT projects with documented field results.
DOT Pre-Approved for Straightforward Project Acceptance
Naming Mirafi on a specification eliminates substitution review delays and ensures the product going in the ground is the one designed for the project.
