Geotextiles are synthetic fabrics used in civil engineering and construction to improve soil stability, drainage, and reinforcement. Made from materials such as polypropylene or polyester, they are designed to be durable, permeable, and resistant to environmental factors like UV exposure and chemical degradation. Geotextiles are commonly used in applications such as road construction, erosion control, drainage systems, and foundation reinforcement. They help separate, filter, reinforce, protect, and drain, enhancing the performance and longevity of infrastructure projects. Available in various forms, including woven, non-woven, and knitted, geotextiles offer versatile solutions for a wide range of engineering needs.
