Why Is Nonwoven Geotextile Fabric Widely Used in Construction?

Nonwoven geotextile fabric is a common material in civil engineering and construction projects. Although it looks simple, it plays an important role in improving ground stability, drainage, and long-term performance. From road construction to drainage systems, this material is used in many practical applications.

This article explains what nonwoven geotextile fabric is, how it’s made, and why it’s so widely used.

What Is Nonwoven Geotextile Fabric?

Nonwoven geotextile fabric is usually made through a needle-punching process. Fibers are mechanically bonded to form a strong and flexible fabric-like material.

The most common raw materials are:

• Polyester (PET)

• Polypropylene (PP)

These materials offer good strength, durability, and resistance to moisture and chemicals.

How Is Nonwoven Geotextile Fabric Made?

In needle-punched nonwoven geotextile fabric, fibers are entangled together using thousands of barbed needles. This process creates a thick and stable structure without using chemical binders.

The result is a fabric that:

• Allows water to pass through

• Blocks soil particles

• Maintains structural integrity under pressure

Main Functions of Nonwoven Geotextile Fabric

Filtration

Allows water to flow while preventing soil and fine particles from passing through.

Separation

Keeps different soil layers from mixing, improving ground stability.

Drainage

Channels water away from structures and foundations.

Protection

Protects membranes or other materials from damage.

Why Use Polyester or Polypropylene?

Polyester (PET)

• High tensile strength

• Good resistance to stretching

• Suitable for long-term applications

Polypropylene (PP)

• Lightweight

• Good chemical resistance

• Common in drainage and separation applications

Material choice depends on project conditions and performance needs.

Things to Consider When Choosing Non woven Geotextile Fabric

Weight and Thickness

Heavier fabrics provide more strength and protection.

Tensile Strength

Important for load-bearing applications.

Water Flow Rate

Must match drainage requirements.

Project Environment

Soil type, moisture level, and load conditions matter.

Testing and proper specification help ensure long-term performance.

Common Installation Tips

• Prepare a smooth surface before laying the fabric

• Avoid excessive stretching during installation

• Overlap joints properly

• Cover promptly to prevent UV exposure

Correct installation improves effectiveness.
