Geotextile

Geotextiles, also known as geotextile fabrics, are permeable synthetic fiber materials made through needle punching or weaving. They are one type of new material geosynthetic, typically in the form of fabric, with widths usually ranging from 4 to 6 meters and lengths from 50 to 100 meters. Geotextiles are categorized into woven geotextiles and nonwoven monofilament geotextiles.

There are mainly three series of geotextiles:

One, needle-punched nonwoven geotextile, available in any specification between 100g/m2 and 600g/m2, primarily made from polyester or polypropylene short fibers through needle-punching technology. Its main applications include riverbank, sea, lake, and embankment erosion control, sea reclamation for farmland, wharf, lock, and flood control engineering. It serves as an effective method for soil and water conservation and preventing pipeline siltation through backwashing.

Two, needle-punched nonwoven geotextile with PE film composite, available in 1 fabric + 1 film, 2 fabrics + 1 film configurations, with a width of 4.2 meters. The main raw material is polyester short fiber needle-punched nonwoven fabric, and the PE film is formed through lamination. Its primary use is for waterproofing, suitable for railway, highway, tunnel, subway, airport, and other engineering projects.

Three, Nonwoven and woven composite geotextiles, including nonwoven and polypropylene filament woven composite, nonwoven and plastic braid composite, suitable for foundation reinforcement and infrastructure for adjusting seepage coefficient.
