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.
