The main reasons for using long filament geotextiles in landfills are as follows:

1.Isolation and protection function: Long filament geotextile has excellent isolation performance, which can effectively isolate garbage and surrounding environment, prevent harmful substances in garbage from leaking into soil and groundwater, and protect the environment and human health.

2. Drainage and filtration function: Long filament geotextile has good drainage and filtration performance, which can effectively remove rainwater and leachate from landfills, preventing leachate from polluting the surrounding environment.

3. Enhance stability: Long filament geotextiles have high tensile strength and tear resistance, which can enhance the stability of landfills and prevent problems such as landslides and collapses.

4. Extended service life: The filament geotextile has excellent corrosion resistance and aging resistance, which can extend the service life of the landfill and reduce maintenance and repair costs.

In short, the application of long filament geotextile in landfills can effectively protect the environment, improve the stability and service life of landfills, and is a very effective protective material.
