Geotextile Filter Mat
Geotextile filter fabric is a black, mesh-like geosynthetic material made from virgin polypropylene granules. It incorporates a specific proportion of carbon black masterbatch, along with anti-aging agents, antioxidants, UV absorbers, and stabilizers. The material is processed by drawing the raw material into oriented round or flat filaments, which are then woven together to create a durable, age-resistant nonwoven geotextile. Geotextile filter fabric features a three-dimensional plastic mesh structure, with permeable geotextile layers bonded on both sides. This innovative material is specifically designed as a filtration solution for landfill applications, primarily used for underground drainage filtration in landfills, surface infiltration control at closure areas, and efficient collection and treatment of leachate.

Detailed description
Overview:
Geotextile filter fabric is a black, mesh-like geosynthetic material made from virgin polypropylene granules. It incorporates a specific proportion of carbon black masterbatch, along with anti-aging agents, antioxidants, UV absorbers, and stabilizers. The material is produced by orienting and stretching the raw material into round or flat filaments, which are then woven together to create an age-resistant, non-woven geotextile. Geotextile filter fabric features a three-dimensional plastic mesh structure, with permeable geotextile layers bonded on both sides. This innovative material is specifically designed as a filtration solution for landfill applications, playing a key role in underground drainage filtration, surface infiltration control at landfill capping systems, and leachate collection and treatment processes.
Product features/benefits:
Seepage control: As a permeable material, geogrids help prevent water loss from soil layers, effectively mitigating soil erosion and natural disasters such as landslides and debris flows.
Reinforcement effect: Geogrids effectively enhance the stability and load-bearing capacity of soil, preventing cracks and deformations in infrastructure such as roads and railways caused by foundation settlement.
Filtering function: Geogrids can filter out impurities and contaminants from soil layers, helping to maintain the stability and permeability of the soil.
Separation function: Geogrids effectively separate and isolate different soil layers, preventing mutual infiltration and contamination between them.
Application scope:
1. Road Construction: In the construction of roads, highways, railways, and other infrastructure, geogrids are used to reinforce roadbeds, prevent foundation settlement, and stabilize road shoulders, among other applications.
2. Hydraulic Engineering: In hydraulic structures such as dams, canals, and flood control systems, geogrids are used to reinforce embankments, prevent seepage, and protect slopes.
3. Civil Engineering: In construction projects such as building construction and basement excavation, geogrids are used to strengthen foundations, reinforce bases, and prevent soil slope failures.
4. Environmental Engineering: In environmental projects such as landfills, manure management, and site remediation, geogrids are used for functions like impermeability, load-bearing, and isolation.
