3. How To Choose Right Non Woven Geotextile Drainage Fabric?

Choosing the right non-woven geotextile drainage fabric involves several key considerations to ensure it meets the specific requirements of your project. Here’s a guide to help you select the appropriate fabric:

3.1 Understand the Project Requirements

• Purpose: Identify the primary purpose of the geotextile (e.g., drainage, separation, filtration, reinforcement).
• Environment: Consider the environmental conditions where the fabric will be used (indoor/outdoor, soil type, water exposure).

3.2 Material Properties

• Permeability: Ensure the fabric has adequate permeability to allow water to pass through while filtering out soil and other particles.
• Durability: Look for high UV resistance and tear strength if the fabric will be exposed to sunlight or heavy use.
• Chemical Resistance: Choose a fabric resistant to any chemicals it might encounter in its environment.

3.3 Fabric Weight and Thickness

• Grammage: The weight of the fabric per square meter (gsm) affects its strength. It also affects durability. Heavier fabrics are generally more durable. They may be less permeable.
• Thickness: Consider the thickness based on the application. Thicker fabrics offer more protection. Protection against root penetration. Also, they provide protection against mechanical damage.

3.4 Filtration Efficiency

• Open Area: The percentage of open area in the fabric is key. It determines filtering capabilities. The fabric can filter out fine particles effectively. At the same time, it allows water to pass through.
• Particle Retention: Ensure the fabric can retain the desired soil particles without clogging.

3.5 Mechanical Strength

• Tensile Strength: Check the tensile strength in both machine and cross directions to ensure it can withstand loads.
• Tear Resistance: High tear resistance is crucial for applications involving heavy equipment or dynamic loads.

3.6 Installation Requirements

• Ease of Installation: Consider the ease with which the fabric can be cut, handled, and installed on-site.
• Compatibility with Other Materials: Ensure compatibility with other materials used in the project, such as soil, concrete, or asphalt.
