Geotextile fabrics are critical technical textiles in civil engineering, used for filtration, drainage, separation, reinforcement, and wrapping/lining functions in projects like roads, railways, dams, landfills, and coastal defenses. The choice of fibers for geotextiles significantly impacts their performance, durability, and suitability for specific geotechnical and environmental engineering applications. Geotextiles are made from synthetic polymers, natural fibers, and occasionally specialty materials like steel wires or glass fibers, each offering unique properties tailored to project requirements. This comprehensive guide lists the fibers used in geotextiles, explains their characteristics, and provides selection criteria to help engineers, contractors, and DIY enthusiasts in the USA choose the right geotextile fiber for their infrastructure projects.

Overview of Geotextile Functions

Before diving into the fibers, it’s essential to understand the principal functions of geotextiles, as these dictate fiber selection:

1. Filtration Function: Allows water to pass through while retaining soil particles, preventing clogging in drainage systems. Nonwoven geotextiles are ideal for filtration and separation in roads and landfills.
2. Drainage Function: Facilitates in-plane or vertical water flow to remove moisture from soil, used as vertical drainage wicks in embankments, railways, and airports.
3. Separation Function: Prevents mixing of dissimilar soil layers (e.g., fine subgrade and coarse aggregate) to maintain structural integrity, saving up to 30% of roadstone in road construction.
4. Reinforcement Function: Distributes loads across earthworks, stabilizing slopes, retaining walls, and dams by providing tensile strength.
5. Wrapping/Lining Function: Acts as a protective barrier or liner to contain soil, waste, or liquids, used in landfill liners, pond liners, and flood protection with geotextile bags (e.g., jute bags).

These functions guide the selection of fibers, as each fiber type contributes differently to strength, permeability, durability, and environmental impact.
