Frequently Asked Questions (FAQ) for Non-Woven Geotextile Fabric

1. What is non-woven geotextile fabric? Non-woven geotextile fabric is a permeable textile material made from synthetic fibers, typically polypropylene or polyester, used in civil engineering, construction, and environmental applications for separation, filtration, reinforcement, protection, or drainage.

2. How is non-woven geotextile fabric made? Non-woven geotextile fabric is manufactured using processes such as needle punching, heat bonding, or chemical bonding to entangle or bond fibers together, creating a strong, durable fabric.

3. What are the common applications of non-woven geotextile fabric?

• Road and railway construction
• Drainage systems
• Erosion control
• Landfills and waste containment
• Soil reinforcement
• Coastal and shoreline protection

4. What are the benefits of using non-woven geotextile fabric?

• High tensile strength and durability
• Permeability for effective drainage and filtration
• Resistance to chemicals, UV radiation, and biological degradation
• Flexibility and ease of installation
• Cost-effective solution for various engineering applications

5. How do I choose the right GSM (grams per square meter) for my project? The choice of GSM depends on the specific needs of your project:

• 80-150 GSM: Lightweight applications like basic drainage and separation.
• 150-300 GSM: Moderate strength requirements for general construction use.
• 300-600 GSM: Heavy-duty projects needing higher tensile strength.
• 600-1200 GSM: Specialized applications requiring maximum strength and durability.

6. Can non-woven geotextile fabric be used for erosion control? Yes, non-woven geotextile fabric is effective in erosion control by stabilizing slopes, embankments, and shorelines, reducing soil erosion and promoting vegetation growth.

7. Is non-woven geotextile fabric environmentally friendly? Non-woven geotextile fabrics are often made from recycled materials and can be recycled after use. They help in environmental protection by preventing soil erosion and controlling pollution in landfills and waste containment.

8. How do I install non-woven geotextile fabric? Installation involves laying the fabric over the prepared surface, ensuring proper overlap between sections, and securing it in place using pins, staples, or weights. It can be easily cut to fit specific project requirements.

9. What is the difference between woven and non-woven geotextile fabric? Woven geotextile fabric is made by weaving fibers together, providing high tensile strength and stability. Non-woven geotextile fabric is made by bonding fibers through needle punching, heat, or chemicals, offering better filtration and drainage properties.

10. How long does non-woven geotextile fabric last? The lifespan of non-woven geotextile fabric depends on the application and environmental conditions. It is designed to be durable and can last for many years when properly installed and maintained.

11. Can non-woven geotextile fabric be used in coastal protection projects? Yes, non-woven geotextile fabric is used in coastal and shoreline protection projects to prevent erosion, stabilize coastal areas, and protect against wave action and storm surges.

12. How does non-woven geotextile fabric improve drainage systems? Non-woven geotextile fabric allows water to pass through while retaining soil particles, preventing clogging and maintaining efficient drainage in various systems like roadways, retaining walls, and landscaping.

These FAQs provide essential information about non-woven geotextile fabric, helping you understand its features, benefits, and applications for your projects.
