Mirafi 135N is a lightweight nonwoven geotextile for everyday separation and filtration work.

This needle-punched polypropylene fabric drains freely while holding soil fines in place, making it a practical choice for underdrains, French drains, and light separation between aggregate and subgrade. Its open structure moves water quickly without letting the soil beneath wash through.

As the entry weight in the N-series, 135N handles residential drainage, landscaping, and lighter site work where you need reliable separation without paying for heavier fabric. It rolls out easily and conforms to trench and slope contours.
