Geotextile series
Made from high-strength industrial synthetic fibers and produced by weaving technology, it has the characteristics of high strength, durability, corrosion resistance, and water permeability.
Used for highways, railways, airports, water conservancy projects, sand reclamation projects, freshwater dock pipe pile bags, soft mattress, environmental protection projects, power engineering, etc.
Reference standard: GB/T17640-2008
