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.
