Non Woven Filter Fabric

4.5 oz non woven geotextile fabric

Non Woven Filter Fabric
120 Grab Tensile Strength

4.5 oz Non Woven Geotextile Filter Fabric

4.5 oz Non Woven Filter Fabric, one step thicker than the 4.0 oz, features a grab tensile strength of 120 lbs., making it the strongest and most rugged of the lightweight non woven filter fabrics. Still offering a high flow through (permeability) and drainage rate, non woven geotextile filter fabric is very effective when used in filtration projects. For projects with more rigorous site conditions needing stronger fabrics, consider mid or heavy-weight non woven filter fabrics.

4.05 oz Non Woven Filter Fabric Applications

The 4.5 oz. non woven geotextile filter fabric is the perfect material for drainage and filtration applications. When compared to medium or heavy-duty models, light weight fabrics offer greater permeability and greater strength than the other light weight non woven filter fabric options. See below for a list of non woven filter fabric applications:


4 oz Non Woven Geotextile Filter Fabric is commonly used in projects such as:

  • Filtration
  • Pipe Wrapping
  • French Drains
  • Asphalt Overlay
  • Beneath Pavers
  • Road Construction
  • Drainage
  • Separation of Soils & Aggregates
  • Sediment Control
  • Slope Stabilization
  • Railroad repair

Light weight geotextiles typically include non woven filter fabrics with a weight from 3 to 5 oz. Non woven geotextile filter fabrics are available in medium weight (5-8 oz) and heavy-weight (9-16 oz) options also. To see our full selection: Non Woven Filter Fabrics.


If strength is more important to your project than filtration, Woven Geotextile Filter Fabric may be what your project needs. Give us a call at 1-863-261-8388 for more information or Contact Us through our web form.


4.05 oz Non Woven Filter Fabric Details

The 4.5 oz non woven geotextile filter fabric is a popular choice for filtration, drainage, stabilization, and separation projects. It still offers the budget benefits of being a light-weight fabric, but it is more durable and stronger than other non woven filter fabrics in its classification. Constructed from a series of needle punched pores, non woven filter fabrics allow water to flow through while blocking sediment and silt.


The 4.5 oz non woven filter fabric boasts a grab tensile strength of 120 lbs and a flow rate 120 gpm. Made of highly durable polypropylene fibers, non woven geotextile filter fabric is highly resistant to UV exposure, rot, degradation from certain chemicals, and other environmental factors. It is also chemically inert and stable from 2 to 13 pH levels. You can check our Nonwoven Geotextiles (PDF).
