Inno-GeosynWoven vs Nonwoven Geotextile: Which Do You Need?
Geotextiles come in two families, and picking the wrong one is a classic (and expensive) mistake. Here's how they differ.
Woven geotextile: strength first
Woven geotextiles are made by weaving polypropylene tapes, like a heavy-duty fabric. They deliver high tensile strength at low elongation — ideal where the fabric must carry load: soft-soil reinforcement, unpaved road stabilization, embankment support. Their filtration is limited compared to nonwovens.
Nonwoven geotextile: filtration first
Nonwoven geotextiles are needle-punched from staple or continuous filament fibers into a felt-like mat. They excel at filtration, drainage and protection: high permittivity, good elongation, and a cushioning effect that shields geomembranes from puncture. Typical uses: drainage trenches, landfill protection layers, separation under pavements.
| Property | Woven | Nonwoven |
|---|---|---|
| Tensile strength | High | Moderate |
| Elongation | Low (10–25%) | High (50%+) |
| Filtration / permittivity | Lower | Higher |
| Puncture protection | Poor | Excellent |
| Best for | Reinforcement, stabilization | Filtration, drainage, protection, separation |
Rule of thumb
Need the ground to hold together? Think woven. Need water to pass through while soil stays put — or need to protect a liner? Think nonwoven. Many road projects actually use both: woven for reinforcement at the subgrade, nonwoven as a separation/filtration layer above.
