ASTM Standard Geotextiles

Geotextiles, also known as geofabrics, are highly permeable synthetic textile materials engineered to interact seamlessly with soil, rock, and other geotechnical elements. Manufactured from advanced polymers such as polypropylene or polyester through weaving or non-woven processes, these fabrics are specifically designed to serve as a critical structural component in geotechnical and civil engineering projects.   Due to their exceptional durability and versatility, multifunctional geotextiles are widely applied across diverse infrastructure sectors. In transportation engineering, they are essential for reinforcing highway and railway subgrades, stabilizing soft soils, and preventing asphalt reflective cracks. In hydraulic and coastal engineering, they play a vital role in riverbank protection, dam construction, and seawall reinforcement to prevent soil erosion and maintain structural stability. Furthermore, these infrastructure fabrics are extensively utilized in environmental and site development projects, including landfill liners, artificial lakes, and foundation drainage systems, providing reliable, long-term support for modern construction.
