Geotextile is a type of fabric used in civil engineering and construction projects. It is made from synthetic or natural fibers and is designed to improve soil stability, drainage, and erosion control. Geotextiles can be woven, non-woven, or knitted, depending on their intended use. These materials are commonly used in applications such as road construction, retaining walls, and landscaping. By separating soil layers, geotextiles help prevent mixing and maintain the integrity of the ground. They also allow water to pass through while filtering out soil particles, making them essential for effective drainage systems.
