Technical Description: A geotextile is a permeable synthetic textile material used in civil engineering and construction works to improve soil performance and provide functions such as separation, filtration, drainage, reinforcement, and protection. It is typically manufactured from polymers such as polypropylene or polyester and is produced in woven, non-woven, or knitted forms depending on the intended application. Woven geotextiles provide high tensile strength for reinforcement, while non-woven geotextiles offer superior filtration and drainage capabilities due to their porous structure. Geotextiles are widely used in road construction, railways, embankments, retaining structures, drainage systems, landfills, and erosion control projects.
Operation: To operate (install) a geotextile, the ground surface is first prepared by removing sharp objects, vegetation, and debris to create a smooth base. The geotextile sheet is then rolled out over the prepared area, ensuring correct orientation and full coverage of the required zone. Adjacent sheets are overlapped or sewn together to prevent soil intrusion. Depending on the application, gravel, sand, or soil is placed over the geotextile carefully to avoid displacement or tearing. In filtration and drainage systems, the geotextile allows water to pass through while retaining soil particles, preventing clogging and soil erosion. In reinforcement applications, it distributes loads and improves soil stability. Proper installation and protection from UV exposure (when uncovered) are essential to maintain long-term performance and durability.
