Road and Rail Separation
A permeable layer between subgrade and aggregate helps limit intermixing; traffic and subgrade conditions determine the required strength.
Nonwoven Geotextile Fabric
Specify needle-punched PP or PET nonwoven geotextile rolls for soil separation, filtration, drainage and geomembrane cushioning. Send your target mass, hydraulic and strength requirements for a project quotation.

Product overview
Nonwoven Geotextile for Project Procurement
A needle-punched nonwoven can act as a separator, a filter or a protective cushion, but the correct grade depends on the site assembly. This page focuses on staple-fiber PP or PET rolls. If your specification calls for a continuous-filament construction, request a separate offer and test schedule.
Select the Performance That Matters
For a drainage filter, provide the soil gradation and required hydraulic performance; opening size and water flow matter alongside mass. For road separation, provide the subgrade and aggregate loading conditions. For geomembrane cushioning, identify the liner, support surface and puncture exposure. A roll described only as “300 gsm geotextile” does not establish suitability for all three uses.
Build a Complete RFQ
Send the required polymer, nominal mass or strength class, tensile and puncture targets, opening-size and permeability requirements, roll dimensions, project quantity and destination. State the governing standard and test methods. The values above are reference indices for quotation; the offered grade’s technical data and any required test documents establish the final specification.
Applications
Drainage Filter Layers
Place around granular drains or drainage composites where soil retention and water passage must be designed together.
Geomembrane Protection
Use as a cushioning layer next to an HDPE liner; select mass and puncture resistance against the actual support surface and overburden.
Embankments and Waterworks
Provide filtration or separation in channels, slopes and bank works when the soil gradation and hydraulic conditions have been assessed.
Key benefits
Needle-Punched Structure
The flexible nonwoven structure conforms to irregular prepared surfaces and can serve as a permeable separator or filter.
Polymer Choice
PP and PET are quoted as distinct material options; confirm chemical exposure and system compatibility for the project.
Protection by Design
Mass, thickness and static puncture resistance provide a practical starting point when choosing a liner cushion.
Clear Procurement Schedule
Request one grade-specific schedule covering mass, tensile strength, puncture, opening size, flow and roll dimensions.
Technical specifications
Staple-fiber procurement reference: values are enquiry targets for the selected grade, with final figures agreed in the offered technical schedule.
| Test Item | Unit | Test Method | Requirement | Result / Notes |
|---|---|---|---|---|
| Mass per unit area — reference grades | g/m² | GB/T 17638-2017 | 200 / 300 / 400 / 500 | Select one nominal grade for quotation |
| Wide-width tensile strength, MD/CD | kN/m | Agree wide-width test method | ≥6.5 / ≥9.5 / ≥13 / ≥16 | Indicative RFQ targets in the same grade order |
| Thickness at stated pressure | mm | Agree pressure and test method | 1.7 / 2.4 / 3.0 / 3.6 | Indicative RFQ targets in the same grade order |
| Static puncture strength | kN | CBR-type test; agree test method | Specify for liner or aggregate loading | A 300 g/m² RFQ may start near 1.5 kN |
| Equivalent opening size | mm | Agree O90/O95 test method | Match design soil gradation | 0.07–0.20 is a common enquiry range |
| Vertical permeability | cm/s | Agree head and test method | Match drainage design | Request the grade-specific test value |

Installation guide
View documents ↓Prepare the Subgrade
Grade the surface and remove protrusions or debris that could damage the selected fabric or any adjacent liner.
Lay and Join Rolls
Unroll without excessive tension. Set overlap or seam details from the project specification, ground condition and placement method.
Place Cover Material
Keep the fabric in position while placing the next layer; control drop height and construction traffic to avoid displacement.
Inspect Before Covering
Check seams, overlaps, tears and continuity, then repair damage according to the approved site method.
Packaging & OEM
Roll Configuration
Quote the selected polymer, nominal mass, width, length and total project area together.
Packing and Identification
Confirm protective wrapping, roll labels and traceability requirements before the order is released.
Documentation
List the test methods, grade schedule and submittals required by the project or destination market.
Export Planning
Share the delivery port, unloading limits and preferred roll dimensions for a workable shipment plan.

Frequently asked questions
Is PP or PET the better choice for my project?
Both can be supplied as needle-punched nonwoven fabrics. Select the polymer against the required mechanical properties, temperature, chemical exposure and system design rather than assuming the two grades are interchangeable.
Can I select a geotextile by GSM alone?
No. Mass is a useful RFQ starting point, but filtration also needs opening-size and water-flow checks, while liner protection needs puncture and thickness checks.
What do the numbers in the table represent?
They are reference grade indices for planning an enquiry, not a batch test report. Request the offered grade's current technical schedule and agreed test methods before approval.
Do you offer a continuous-filament grade?
Ask for a separate quotation and technical schedule. Continuous-filament and staple-fiber nonwovens have different constructions and should be evaluated against their respective requirements.
What should I send for a quote?
Send the application, polymer preference, required grade or performance limits, roll width and length, total area, destination and required documents.
