What is Non-Woven Geotextile?
Non-Woven Geotextiles are permeable fabrics that, when used in association with soil, can separate, reinforce, protect, or drain. Typically made from polypropylene or polyester, geotextile fabrics come in three basic forms: woven (resembling mail bag sacking), needle punched (resembling felt), or heat bonded (resembling ironed felt). A woven geotextile is manufactured from continuous filaments or strips of synthetic material which are woven together to form a uniform sheet.
A non-woven geotextile has a very uniform pore size which varies under load making it less suitable for filtering anything other than clean single-sized soils/fills.

Difference between Woven and Non-Woven
Woven Geotextile
- 1. Constructed from interlaced yarn, polypropylene, or other fibers
- 2. Semi-impermeable lower flow-through rate
- 3. High tensile strength and load capacity
- 4. Great for Stabilization and Reinforcement Applications
Non-Woven Geotextile
- 1. Typically made of needled punched synthetic fibers
- 2. Permeable with higher drain through flow rate
- 3. Measured by weight, commonly referred to as ounces/sq. yard
- 4. Excellent for drainage, separation, and filtration applications
