Mirafi® Nonwoven Geotextile Drainage Fabric
One of our other popular mid-weight nonwoven drainage fabrics is the Mirafi® N-Series polypropylene nonwoven geotextile. This nonwoven geotextile fabric is constructed to easily conform to ground or trench surfaces for problem free installation. The N-series’ high flow-through rate makes this geo drainage fabric perfect for French drains, as well as other soil separation, drainage and filtration applications.
Mirafi® geotextile for drainage and filtration eliminates the challenge of determining aggregate gradation required to match soil conditions, ensuring effective filter performance.

6 oz. Nonwoven Geotextile Drainage Fabric Details
This 6 oz nonwoven geotextile drainage fabric is part of our medium weight geotextile fabric line for drainage, asphalt overlay, and filtration projects. Mid-weight non woven geotextile fabrics are stronger and more rugged than lighter-weight drainage geotextiles, but still provide a reliable flow-through rate for stormwater. Geotextile non woven drainage fabrics are available in weights from 3 to 16 oz, with lower weights offering greater flow and higher weights providing greater strength to meet site-specific specs.
Made from UV and pH stabilized polypropylene fibers, this needle punched nonwoven geotextile drainage fabric drains quickly while providing a protective barrier against erosion. The felt-like drainage geotextile fabric filters and retains sediment as stormwater flows through, resists rotting and deterioration, and offers a long active use life in the field. With strong permittivity and flow ratings, 6 oz nonwoven geotextile fabric can handle demanding drainage and filtration applications.

6 oz. Nonwoven Geotextile Drainage Fabric Applications
If you are responsible for keeping bases stable and drainage working on a site, 6 oz nonwoven geotextile drainage fabric is often the “just right” option. It is strong enough to support traffic and loads, but still open enough to let water move through so your aggregate base does not pump, rut, or wash out.
In the field, contractors, engineers, and municipal crews rely on this mid-weight drainage geotextile under gravel roads and driveways, along French and trench drains, behind retaining walls, and on slopes or embankments where erosion control and soil separation are critical. It also shows up in landfill lining and stabilization, earth retaining structures, and as a protective underlayment where liners or surfacing need a stable, well-drained base.
On lighter-duty civil and landscape projects, the same fabric pulls double duty as an underlayment under walkways and driveways, a separator between soil and decorative stone, and a pond underlayment that helps protect liners while allowing water to move through surrounding soils. Whenever you need to manage site drainage and protect your aggregate from mixing into the subgrade, 6 oz nonwoven drainage fabric is a practical, easy-to-handle choice.
Typical project types include:
- Site drainage management, French drains, and trench drains
- Road construction, railroad repair, and driveway or walkway separation
- Slope reinforcement, erosion control, and earth retaining structures
- Landfill lining, pond underlayment, and general landscaping underlayment

6 oz. Nonwoven Geotextile Drainage Fabric Installation
Follow these general guidelines to install 6 oz nonwoven geotextile drainage fabric. Always follow project specifications and engineer-approved drawings when available, as site conditions may require adjustments.
- Prepare the Subgrade: Clear the area of debris, roots, sharp objects, and standing water. Grade and compact the subgrade as required.
- Place the Fabric: Unroll the nonwoven geotextile drainage fabric in the direction of the work, keeping it smooth and free of wrinkles or folds.
- Overlap Seams: Overlap adjacent edges according to project requirements (commonly 12–24 inches) to maintain continuous soil separation.
- Secure the Fabric: Use staples, pins, or ballast as needed to hold the geotextile in place, especially on slopes or in windy conditions.
- Place Backfill or Aggregate: Install gravel, soil, or other specified materials over the fabric, avoiding direct contact with sharp equipment edges that could damage the geotextile.
6 oz. Nonwoven Geotextile Drainage Fabric - Frequently Asked Questions
Both woven and nonwoven geotextile fabrics are nonbiodegradable, UV and rot resistant, and allow water to pass through. Woven geotextiles are made on industrial looms and offer very high tensile strength, so they are often used where reinforcement is the priority. Nonwoven geotextile drainage fabrics are needle-punched into a thicker, felt-like material that conforms to the ground and provides excellent filtration and drainage. For most drainage, separation, and underlayment applications, a nonwoven geotextile like this 6 oz fabric is the typical choice.
Key measurements for nonwoven geotextiles include fabric weight (oz/yd²), strength values, and flow or filtration properties. Weight gives a quick sense of how robust the fabric is; 6 oz is a mid-weight that balances strength and drainage. Grab tensile, tear strength, and CBR puncture resistance describe how the fabric will handle loads and installation stresses. Permittivity, permeability, and AOS (Apparent Opening Size) indicate how easily water can move through the fabric and how effectively it filters soil. Together, these measurements help match the fabric to your drainage, separation, and erosion control requirements.
