Filament geotextiles: filament geotextile acupuncture for polyester filament non-woven geotextile, do not contain chemical additives, are not heat treated, is environment-friendly building materials. It can replace the traditional engineering materials and construction methods, construction safety, and contribute to environmental protection, more economic, effective, durable solutions to basic issues in engineering construction. Geotextile filament mechanical function is good, good water permeability, and resistance to corrosion, anti-aging, with isolation, filtration, drainage, protection, stability, reinforcement and other functions, can adapt to uneven base construction, to resist external damage, creep, can still maintain the original function under long-term load. The company is specialized in the production of various specifications of geotextile, weight: 120g/ square meters --900g/ square meters, the largest single width up to 8 meters, in the same industry belongs to the width of the widest, weight the highest product, is unmatched by other enterprises.
