Mirafi 140NL/O Orange Delineation Geotextile Fabric - 15' x 360' Roll - Solmax
FREE SHIPPING
This Mirafi orange delineation geotextile combines proven nonwoven separation with a high-visibility warning layer.
Built on the same needle-punched polypropylene platform as the standard N-series, the orange fabric separates and drains while its bright color acts as a buried marker, alerting future crews that they have reached the boundary of engineered fill or a utility zone.
It is specified where separation and a visual warning are both needed, adding a safety and delineation function to everyday drainage and stabilization work without sacrificing fabric performance.

Why Choose Mirafi 140NL/O?
5 reasons this orange delineation geotextile outperforms generic alternatives
Built-In Layer Identification
The high-visibility orange coloring is integrated into the fabric — not a surface coating — making it easy to identify geotextile placement layers during inspection, documentation, and future excavation.
Same Performance as Standard 140NL
The orange delineation version meets identical ASTM filtration, separation, and strength specifications as standard 140NL — you don't sacrifice performance for visibility.
Accepted for Delineation Specs
When project plans call for visually delineated geotextile layers, Mirafi NL/O meets that requirement. Generic fabrics typically cannot be specified as a compliant substitute on delineation-required projects.
USA-Made, BABA Eligible
Produced in Georgia, Mirafi 140NL/O can meet Build America / Buy America requirements on federally funded projects — a compliance advantage orange-dyed imports cannot reliably provide.
TenCate Quality Assurance
Every roll is manufactured under TenCate's ISO-certified quality system with documented test data per ASTM standards — giving inspectors and owners confidence that the fabric meets spec before it goes in the ground.
