Geotextile Filter Fabric
Geotextiles have been widely used in various engineering projects over the past thirty years due to their excellent mechanical properties. These advanced geotextiles have excellent isolation, anti-seepage, drainage and reinforcement functions, far exceeding the performance of ordinary polypropylene geotextiles. Their good hydrophobicity further enhances their durability and application effect. From infrastructure construction to environmental protection, geotextiles have proven to be a reliable and long-lasting solution that can meet the high requirements of modern engineering practice.
Geotextile Filter Fabric excels in engineering and environmental protection, offering durability, recyclability, and pollution-free performance.With its multifunctionality and environmental benefits, Geotextile Filter Fabric has become an essential material in modern engineering and environmental protection, providing reliable support for sustainable development.
Application Scenarios:
Geotextile Filter Fabric is widely used in various engineering and environmental scenarios, including:
Road and Railway Engineering: Used for subgrade isolation, drainage, and reinforcement to prevent soil erosion and extend service life.
Hydraulic Engineering: Applied in dams, channels, and reservoirs for anti-seepage, filtration, and drainage, ensuring structural stability.
