  • Lightweight and economical

3.5 oz Non Woven Filter Fabric Details

Geotextile non woven filter fabric rolls are made from virgin polypropylene fibers, then punched with barbed needles to create the geotextile's felt like texture and filtration properties. Non woven filter fabric is not biodegradable and will last indefinitely once installed underground. Additionally, it is UV resistant, pH stabilized, resistant to rodents and insects, and will not rot or mildew. With a 150 gpm/ft flow rating, it can withstand high flow projects with ease. Geotextile non woven filter fabric is well suited for jobs needing 2 sec-1 permittivity and an apparent sieve opening of 50 US Sieve.

Filter Fabric Roll Sizes: Sold by the roll or by the pallet:

  • 12.5' W x 360' L (4,500 ft²) | 3.8m W x 109.7m L
  • 15' W x 360' L (5,400 ft²) | 4.6m W x 109.7m L

3.5 oz Non Woven Filter Fabric Applications

As one of four lightweight geotextile non woven filter fabric options, 3.5 oz accommodates a remarkably high flow rate while still providing good filtration and erosion control results. Truly a multi-purpose solution, non woven filter fabric rolls are often ordered in bulk as a convenient way to keep a ready supply on hand at the best pricing available.

Choose the type of geotextile non woven filter fabric needed based on the specific project requirements. Geotextile non woven fabric is available in light weight (3.1, 3.5, 4, 5 oz), medium weight (6, 8 oz), and heavy weight (10, 12 and 16 oz) options.

Use 3.5 oz geotextile non woven filter fabric rolls for:

  • Bank Stabilization: Sustains unstable banks, adding support to soil and sediment
  • Erosion and sediment control: With strong soil retention, protects slopes and banks from the effects of erosion
  • Underlayment: Non woven filter fabric as underlayment for road construction will reinforce soil on jobsites. Using tear resistant geotextile non woven filter fabric as an underlayment will prolong the life of your driveway or road.
  • Filtration/Drainage: Stormwater passes through while sediment and debris is retained
  • Soil stabilization: Sloping location with poor soil quality are given strength

3.5 oz Non Woven Filter Fabric Installation Instructions

For use as a guide, general non woven filter fabric installation instructions are listed below. When available, it is best to use specific instructions designed for your project's unique conditions and environment.

  • First, remove anything on the surface of the ground that could impede the non woven filter fabric. This can include rocks, debris, stumps and sharp objects that could damage the geotextile non woven filter fabric.

  • Once all debris is removed, you should smooth the install area, leveling it.

  • Placement pattern of each filter fabric roll will depend on the project plan.

  • Secure the non woven filter fabric with staples, overlapping the edges of 12-18". Pay special attention to the overlapping edges.

  • Geotextile non woven filter fabric will require a backfill over the fabric of at least 6".
