3.1 oz Nonwoven Lightweight Geotextiles for Drainage and Filtration

filtration geotextiles, geotextiles, erosion control fabricThe 3.1 oz. nonwoven geotextile is a lightweight fabric used in filtration, drainage, paving, and various other landscaping applications. Whether wrapped around a drain or used to support a paver, these geotextiles can provide a combination of both strength and filtration. Common applications for 3.1 oz nonwoven geotextiles include:

  • French Drains
  • Subsurface Drains
  • Asphalt Overlay
  • Support Under Pavers or Roads

Nonwoven geotextiles shown here feature a 3.1 ounce weight, 80 pound grab tensile strength, and approximate Apparent Opening Size (AOS) of #50 US sieve. This allows for high a level of water to pass through the fabric when used in drainage or filtration areas. Additional fabrics, higher strengths, and woven models are also available.

Nonwoven Filtration Geotextile Applications

Nonwoven filtration geotextiles are a high quality filter fabric that can be used for a variety of drainage and filtering applications. These geotextiles are designed to retain fine particles when water passes from fine grained to coarse grained soil layers. This helps keep particles separated and prevents water from building up and causing erosion. Common applications include the following:

  • Soil Erosion Prevention
  • Stabilization Under Pavers
  • Erosion Control and Repair
  • Soil Restoration Applications
  • Drainage and Filtration Requirements
  • Drainage and Gas Venting
  • Asphalt Overlay

For increased stabilization or strength, geotextiles are also available in additional lightweight, medium weight, and heavyweight fabrics. View the table below for more information on each of these fabrics and how they can be used in erosion control areas.

Not Sure Which Needle Punched Geotextile You Need?

Nonwoven Filtration Geotextiles are typically classified into three categories based on their weight. Lightweight geotextiles range from 3 oz. to 5 oz. in weight, while medium weight geotextiles range from 6 oz. to 8 oz. and heavy weight geotextiles range from 10 oz. to 16 oz. Please feel free to view the chart below for more information on each of these fabrics and where they can be used.
