Long filament geotextile, also known as polyester filament needle punched non-woven geotextile, is a non-woven material made from polyester filament through needle punching process. It does not contain chemical additives and has not undergone heat treatment, therefore it has good environmental characteristics.

Main features: Long filament geotextiles have excellent heat and light resistance, and their performance remains almost unchanged even after short-term exposure to high temperature environments. In addition, it also has long-term corrosion resistance to various natural soils, moisture, and microorganisms.

Function: Long filament geotextile can provide sexual isolation, long-term isolation of soil layers with different components and properties, and prevent their mixing. At the same time, it also has good anti filtration and anti-corrosion properties, and can withstand frost and the load-bearing requirements required for construction.

Application areas: Long filament geotextiles are widely used in civil engineering projects such as rivers, railways, highways, bridges, and cofferdams. It can effectively prevent soil collapse and erosion, improve the overall strength of the soil, increase the bearing capacity of the foundation, and ensure the stability of the project.
