Non Woven Geotextile Filter Fabric
Heavy-Duty Filter Fabric
With excellent strength and filtration properties, the 10 oz. non woven geotextile filter fabric is one of the strongest geotextiles available, with a 250 lb grab tensile strength. While 10 oz. geo filter fabric matches the strength of many woven materials, its needle-punched design allows for better water flow and filtration. It's ideal for tough applications like road bases, slopes, and retention ponds.
Non Woven Geotextile Filter Fabric Features
- Grab tensile rating of 250 lbs.
- 700 lb. puncture resistance rating
- Flow rating of 80 gpm/ft²
Non Woven Geotextile Filter Fabric Benefits
- Superior strength
- High level of filtration
- Rot resistant and long lasting
Non-Woven Geotextile Filter Fabric Details
The 10 oz non woven filter fabric is a heavy weight, high-strength material designed for filtration and soil stabilization. Made from needle-punched polypropylene fibers, it offers high water permeability and resists rot, UV exposure, and naturally occurring chemicals. This non woven geotextile is pH stable, cost-effective, and performs comparably to woven filter fabrics in strength.
Its 3D-structured surface delivers a sieve rating of 100, a permittivity of 1.2 sec⁻¹, and a flow rate of 80 gpm/ft². Common uses include slope stabilization, aggregate separation, erosion control, and cushioning for geomembranes in retention ponds.
For other material options, see our Geotextile Fabric Specifications Chart.
Available Sizes (sold by the roll or pallet):
- 12.5' W x 360' L (4,500 ft²/roll) | 3.8m W x 109.7m L
- 15' W x 300' L (4,500 ft²/roll) | 4.6m W x 91.4m L
Other Geotextile Options:
- Woven Fabric 200: Medium strength with moderate filtration
- Woven Fabric 150: Lightweight with higher permeability
- Mirafi® Mscape: Flexible and easy to install for light landscaping and weed control
Mirafi® N-Series Filter Fabric:
The Mirafi® N-Series non woven filter fabric is another high-strength option. This polypropylene geotextile conforms easily to ground or trench surfaces, making it ideal for French drains and drainage installations. Its high flow-through rate and durability make it a strong choice for filtration, separation, and erosion control applications.
The N-Series eliminates the need to calculate aggregate gradation to match specific soil types. Learn more about Mirafi® N-Series or explore all options on our Mirafi® Overview page.

Non Woven Geotextile Filter Fabric Applications
The 10 oz non woven geotextile filter fabric is built for demanding applications that require filtration, strength, and flexibility. Commonly used beneath roads, driveways, and sports fields, it prevents mixing between subsoil and aggregates while supporting drainage and erosion control. This geotextile fabric also wraps around pipes, protects pond liners, and stabilizes slopes where shifting or runoff is a concern.
Ideal uses for 10 oz non woven filter fabric include:
- Road and Driveway Underlayment
- Drainage Wraps for Pipes and Systems
- Slope and Embankment Stabilization
- Separation Between Rock and Subgrade Soil>
- Pond Liner Cushioning and Protection
Non Woven Geotextile Filter Fabric Installation
The steps below outline general installation guidelines for 10 oz non woven geotextile filter fabric in drainage applications. Always follow site-specific instructions when available, as they may override general recommendations.
- Clear the area of rocks, stumps, and debris to prevent fabric damage.
- Grade the surface until smooth and even to allow proper placement.
- Roll out the fabric per the site plan, overlapping edges by 12–18 inches.
- Secure the fabric with landscape staples, especially at overlaps and edges.
- Backfill with at least 6 inches of soil or aggregate; unstable soil may require more.

Non Woven Geotextile Filter Fabric Frequently Asked Questions
This will depend on the specifics of the project, but the 10 and 12 oz. non woven geotextile filter fabric is common for most average ballasts in railway construction projects. The 14 oz. geoxtextile fabric and 16 oz. geotextile fabrics are used for more rigorous site conditions. This is according to AREMA (American Railway Engineering and Maintenance-of-Way Association).
The 10 oz. non woven geotextile fabric can be placed either above or below the membrane to protect a geomembrane liner from puncture in retention or detention ponds. Placed below the membrane, it protects it from being damaged by any rocks or objects in the soil bed. Placed above the membrane, the 10 oz. geotextile fabric protects the membrane from damage that can occur on its surface.
