Mirafi 170N Geotextile Fabric - 15' x 300' Roll - Solmax
FREE SHIPPING
Mirafi 170N is a nonwoven geotextile built for separation, drainage, and subgrade stabilization.
Needle-punched polypropylene gives 170N a strong balance of water flow and puncture resistance, letting it separate base course from soft soils, drain saturated ground, and stabilize working platforms. It filters fines while maintaining permeability.
Specified for subsurface drainage, separation, and stabilization across many road and site projects, 170N stands up to heavier aggregate and construction traffic than the lighter N-series fabrics.

Why Choose Mirafi 170N?
5 reasons engineers specify Mirafi N-Series over generic nonwoven geotextiles
Heavy-Duty Strength for Demanding Installs
The 170N offers elevated grab tensile and puncture resistance suited for applications with aggressive subgrade conditions, heavy construction traffic, or large angular stone — where lighter fabrics risk damage during placement.
Reliable Separation in Challenging Soils
Engineered for effective separation between subgrade soil and aggregate layers, the 170N prevents subgrade pumping and contamination over the design life of the structure — outperforming generic fabrics that may creep or degrade.
Fully Documented ASTM Performance
Mirafi 170N's grab tensile, puncture, AOS, and permittivity values are published and verifiable per ASTM standards — essential for project submittals where performance documentation is required.
USA-Made, BABA Eligible
Manufactured in Georgia, Mirafi 170N can meet Build America / Buy America requirements on federally funded road, utility, and infrastructure projects.
Backed by Decades of Civil Project History
TenCate Mirafi N-Series fabrics have been specified on DOT and civil infrastructure projects for over 40 years. That documented field history provides engineers with a level of confidence no generic nonwoven can match.
