Mirafi®Nonwoven Fabric Installation Instructions
Use as a guide, general nonwoven Mirafi® Mscape landscaping installation are listed below. It is best to use specific instructions designed for your project's unique conditions and environment.
- First, cut N series fabric prior to placement.
- Width should be enough to conform to the trench perimeter with at least a 6in (15cm) top overlap
- Place the soil separator roll over the trench, and unroll enough that fabric can be placed down into the trench.
- Anchor edges of the N series fabric with heavy objects to prevent fabric from falling into the trench.
- Where overlaps are necessary between rolls, allow for 3 ft. overlap from the upstream to downstream roll.

Non-Woven Filter Fabric Frequently Asked Questions
Mirafi® nonwoven geotextile fabric is a synthetic permeable fabric made by needle-punching the fibers during manufacture. This makes the fabric easily recognized by its felt-like appearance and texture. Non woven geotextiles are commonly used for filtration or separation in construction or erosion control projects.
Geotextiles are classified as either woven or nonwoven. As the name indicates, the main difference between the two products is how they are manufactured. Woven geotextiles are woven together with industrial looms in a consistently applied pattern. Nonwoven geotextiles are manufactured with a needle-punch process, using barbed staples to create a felt-like permeable fabric. Give us a call to find the right geotextile for you at 863-261-8388.
