Needle Punched Nonwoven Geotextile Fabric

Our needle punched nonwoven geotextile fabric is manufactured from high-quality polyester (PET) or polypropylene (PP) staple fibers through carding, web forming and mechanical needle punching. The interconnected three-dimensional fiber structure provides a combination of permeability, filtration, separation, drainage and protection for civil engineering and geotechnical applications.

Available in a wide range of weights from 100 to 800 GSM, the geotextile can be customized according to project requirements for thickness, width, weight, material, color and roll length.

It is widely used in road construction, highways, railways, drainage systems, retaining walls, landscaping, foundation engineering, erosion control and other civil engineering projects.

Key Functions of Nonwoven Geotextile

1. Filtration

The porous needle-punched structure allows water to pass through while helping retain soil particles and fine materials.

This makes nonwoven geotextile suitable for:

• Drainage pipe wrapping
• French drain systems
• Retaining wall drainage
• Foundation drainage
• Subsurface drainage
• Road drainage systems
• Soil and water filtration

The filtration and permeability characteristics are among the main reasons needle-punched nonwoven geotextiles are widely used in drainage applications.

2. Drainage

The interconnected fiber structure creates continuous voids through the fabric, allowing excess water to move through the geotextile.

It can be used as a drainage layer in:

• Roads and highways
• Foundations
• Retaining walls
• Landfills
• Drainage trenches
• Underground drainage systems
• Landscape drainage
• Civil engineering projects

For drainage applications, the appropriate GSM and permeability should be selected according to soil conditions, water flow requirements and project design.

3. Soil Separation

Nonwoven geotextile helps separate different layers of soil, sand, gravel and aggregate while allowing water to pass through.

For example, it can be installed between:

Soil → Geotextile → Aggregate

to help reduce the mixing of fine soil particles with the aggregate layer.

This function is particularly important in road and foundation construction where separation between subgrade and aggregate is required.

4. Protection

The flexible felt-like structure can also act as a cushioning and protective layer between soil, aggregate and other geosynthetic materials.

Typical applications include:

• Geomembrane protection
• Waterproofing system protection
• Landfill liner protection
• Foundation protection
• Tunnel waterproofing protection

• Underground engineering

  
  

PET vs PP Nonwoven Geotextile

We can manufacture nonwoven geotextiles using polyester (PET) or polypropylene (PP) staple fibers, depending on the requirements of the application.

PET and PP are both widely used for needle-punched nonwoven geotextiles, but the appropriate material should be selected according to the project environment and required mechanical/hydraulic properties.

Available GSM

Our needle punched nonwoven geotextile can be supplied in different weights according to the required application.

100-200 GSM

Suitable for relatively lightweight filtration, drainage and separation applications.

200-400 GSM

Suitable for general civil engineering, drainage, landscaping, road construction and soil separation applications.

400-600 GSM

Suitable for applications requiring higher mechanical strength, puncture resistance and protection.

600-800 GSM

Suitable for heavier-duty civil engineering and geotechnical applications where greater thickness and mechanical performance are required.

GSM selection should be based on the actual project requirements rather than weight alone.

Applications

Road & Highway Construction

Needle punched geotextile can be installed between the subgrade and aggregate layers to provide separation, filtration and drainage.

Typical applications include:

• Highway construction
• Road base stabilization
• Rural roads
• Pavement construction
• Road widening
• Temporary roads
• Soft soil foundation treatment

Needle-punched geotextiles are commonly used in highway engineering because their flexible fiber structure can conform to uneven ground while providing filtration, drainage and separation.

Drainage Systems

Geotextile filter fabric is widely used around drainage materials and perforated pipes.

Typical applications:

• French drains
• Perforated pipe wrapping
• Foundation drains
• Retaining wall drainage
• Drainage trenches
• Underground drainage

• Landscape drainage

  
  

Railway Engineering

Nonwoven geotextile can be used in railway subgrade and drainage systems for separation, filtration and protection.

Retaining Walls

Installed behind retaining walls, geotextile filter fabric can help separate soil from drainage aggregate while allowing water to pass through.

Landscaping & Paving

Applications include:

• Paver base separation
• Walkways
• Garden drainage
• Landscape construction
• Gravel paths

• Parking areas

  
  

Hydraulic & Environmental Engineering

Depending on the specification, nonwoven geotextile can be used in:

• Dams
• Reservoirs
• Canals
• Drainage channels
• Erosion control
• Landfill systems
• Wastewater-related infrastructure

• Coastal engineering

  
  

Manufacturing Process

Our needle-punched nonwoven geotextile is produced through a mechanical fiber-entanglement process.

Raw Fiber

PET or PP staple fibers are selected according to the required product specification.

↓

Fiber Opening & Blending

The fibers are opened and blended to achieve a more uniform fiber distribution.

↓

Carding & Web Formation

The fibers are carded and formed into a uniform nonwoven web.

↓

Needle Punching

Barbed needles mechanically entangle the fibers to form a stable three-dimensional nonwoven structure.

↓

Finishing & Inspection

The fabric is inspected according to the specified GSM, width, thickness and performance requirements.

↓

Roll Packing

The finished geotextile is supplied in rolls or customized formats according to customer requirements.

The needle-punching process is particularly important because the mechanically entangled fibers create the characteristic porous structure used for filtration, drainage and separation.
