Introduction
Woven geotextiles are synthetic fabrics manufactured by systematically interlacing yarns in a structured pattern. These engineered textiles provide reinforcement, separation, and filtration in geotechnical, civil engineering, and environmental projects. Unlike non-woven geotextiles, which have a random fiber arrangement, woven types offer superior strength and predictable performance due to their uniform weave.
Applications
- Road Construction: Reduces rutting by separating subgrade from aggregate.
- Railway Tracks: Stabilizes ballast layers.
- Erosion Control: Protects slopes and retaining walls.
- Coastal Protection: Prevents soil washout in revetments.
- Landfills: Act as a separator in waste containment systems.
- Mining: Reinforces haul roads and tailings dams.
Introduction
Non-woven geotextiles are specially engineered fabrics made from synthetic polymer fibres such as polypropylene or polyester. Unlike woven fabrics, these are created by bonding fibres through mechanical needling, heat treatment, or chemical binding. They serve vital roles in civil, environmental, and geotechnical works by performing separation, filtration, drainage, and protection functions. Owing to their high strength, permeability, and resistance to environmental wear, they are widely adopted in roads, erosion control, landfills, and water management projects.
Applications

- Landfill Engineering: Cushioning and protecting geomembranes while managing leachate flow.
- Erosion Protection: Under riprap or gabions to stop soil loss at coasts and rivers.
- Sports & Landscape Projects: Enhances drainage and soil stability.
- Underground Works: Provides drainage and protection in tunnels.
