1. The geotextile filter has strong drainage ability (equivalent to one meter thick gravel drainage),
2. 200g geotextile filter has high tensile strength,
3. The geotextile filter in landfill sites can reduce the probability of geotextile embedding into the mesh core and maintain long-term stable drainage;
4. The geotextile filter can withstand high pressure loads for a long time (able to withstand compression loads of approximately 3000Ka);
5. "Corrosion resistant, acid and alkali resistant, long service life filter" standard.
The geotextile filter must have a certain degree of fracture strength, elongation at break, and bursting to ensure that it will not be damaged. Geotextile filters must have a certain degree of UV resistance to ensure that their material properties are maintained before landfilling. Geotextile filters can be used to effectively filter various foundation soils. Laying a geotextile filter on the foundation soil can effectively filter groundwater, ensuring the stability of the contact surface between the foundation soil and the drainage layer. It has good fracture strength, fracture elongation, and top breaking, ensuring that it can resist the local stress generated by the drainage layer below the garbage.

Application of Geotextile Filter
The geotextile filter is composed of a three-dimensional plastic mesh with double-sided adhesive permeable geotextile, which can replace traditional sand and gravel layers. It is mainly used for drainage in landfills, roadbeds, and tunnel walls. This information is sourced from . In transportation infrastructure such as railways and highways, the safety and service life of engineering are closely related to its own drainage system, among which geosynthetics are an important component of the drainage system. Meet the application requirements of environmental protection and sanitation, water conservancy, construction, municipal engineering, landscaping, petrochemicals, mining, salt industry, agriculture, and aquaculture.
