Woven vs Nonwoven Geotextile: Geotextile Nonwoven Fabric Guide Pakistan
.
Woven vs nonwoven geotextile difference is construction, filtration and cost — nonwoven is needle punched PP/PET for drainage filtration — woven is woven tape for separation reinforcement — see glossary and what is nonwoven fabric. Olefins Pakistan supplies geotextile nonwoven fabric 100-800 GSM ex-stock Karachi as per product portfolio and TDS per product and textile nonwoven and interlining.
What is Geotextile Nonwoven Fabric?
Geotextile nonwoven fabric is needle punched or thermal bonded PP or PET 100-800 GSM, width 1-6 meter, for separation, filtration, drainage, protection in roads, railways, landfills, retaining walls, river banks — GSM as per GSM guide and width as per width guide. For bonding see spunbond and spunbonded olefin vs spunbond PP and SMS vs SMMS. For sourcing see sourcing guide and quality and innovation and TDS library. Olefins geotextile is UV stabilized for Pakistan climate with 24 months shelf life as per MSDS.
Woven vs Nonwoven Geotextile — Difference Table
As per TDS — FOB Karachi — info@olefins.net — Olefins Pakistan — width 1-6 meter
| Feature | Woven Geotextile | Nonwoven Geotextile (Olefins) |
|---|---|---|
| Construction | Woven PP tapes — warp/weft | Needle punched PP/PET — as per spunbond |
| GSM | 100-400 | 100-800 as per TDS — see GSM guide |
| Function | Separation + reinforcement — high tensile | Filtration + drainage + protection — low clogging |
| Permeability | Low — 0.01-0.05 cm/s | High — 0.1-0.3 cm/s — as per ISO 11058 |
| Tensile | High 20-80 kN/m | 10-50 kN/m as per ISO 10319 — see TDS |
| Application | Roads subgrade separation | Drainage, landfill, railway — see textile nonwoven |
| Elongation | Low 10-20% | High 40-80% — better conformability |
| Cost | Higher per m2 | 30-40% lower — as per sourcing guide |
How to Choose Geotextile GSM
100-200 GSM → separation light roads, filtration — tensile 10-20 kN/m — AOS 0.12-0.20 mm
200-400 GSM → drainage, railway, landfill protection — tensile 20-35 kN/m — most common in Pakistan — see width guide
400-800 GSM → heavy protection, landfill liner — puncture >3000 N — CBR >4000 N — see GSM chart and TDS library
Geotextile Nonwoven Fabric — Specs As per TDS
Olefins geotextile nonwoven: 100% PP/PET needle punched, GSM 100-800 tolerance ±5%, width 1-6 meter tolerance ±1%, roll length 50-200 meter, thickness 1.0-6.0 mm as per ISO 9863, tensile 10-50 kN/m as per ISO 10319, elongation 40-80% as per ISO 10319, CBR puncture 1500-6000 N as per ISO 12236, AOS 0.08-0.20 mm as per ISO 12956, permeability 0.05-0.30 cm/s as per ISO 11058, grab tensile 600-2500 N as per ASTM D4632 — as per TDS-OLE-GEO-100-800. UV stabilized with 2% carbon black for Pakistan climate. Width tolerance ±1%, GSM tolerance ±5%. Roll length formula as per width guide: Length = Weight × 1000 / (Width × GSM) and area = Length × Width. Always order by m2, not kg. Lot-specific TDS, COA per lot — see TDS library and quality and innovation. For GSM comparison see GSM guide.
Woven vs Nonwoven Geotextile — Which to Use in Pakistan Projects?
Use woven when you need high tensile separation and reinforcement for soft subgrade roads — low elongation 10-20% prevents subgrade mixing and reduces aggregate thickness 15-25%. Use nonwoven when you need filtration and drainage — nonwoven allows water to pass while retaining soil particles — ideal for behind retaining walls, French drains, landfill leachate drainage, railway track bed, river bank protection. Many NHA and WAPDA projects in Pakistan use both — woven at bottom for separation, nonwoven on top for filtration and protection of geomembrane. For procurement see product portfolio and sourcing guide. For comparison see SMS vs SMMS and interlining and furniture.
