Staple Geotextile Water Permeable and Filterable for Soil Stabilization
Product Introduction
Staple fiber geotextile is a widely used geosynthetic material, which is mainly made of staple fiber through nonwoven process.
Product Properties
1. Isolation: As an isolation layer between different materials to prevent material mixing and maintain the integrity of the structure.
2. Corrosion resistance: It has good resistance to most chemical substances and is suitable for a variety of environmental conditions.
3. Resistance to biological erosion: Good resistance to microbial and insect erosion.
4. Aging resistance: It has certain anti-ultraviolet and weather-aging properties, extending the service life.
5. Water permeability: Staple fiber geotextiles allow water to pass through, helping water discharge and reducing pore water pressure in the soil.
6. Filterability: can prevent the loss of fine particles of soil, while allowing the flow of water, play a good filtering effect.
7. Reinforcement: Enhance the stability of soil or rock, improve the bearing capacity and durability of the project.
Product Application
1. Civil engineering: Used as reinforcement and isolation materials in the construction of tunnels, subways, airports and other infrastructure.
2. Slope engineering: Used for slope protection to prevent soil erosion and landslides.
3. Soil erosion control: used to control soil erosion and protect soil and vegetation.
4. Road and railway construction: improve the bearing capacity and stability of the roadbed and extend the service life of the road.
5. Hydraulic engineering: used for reinforcement and filtration in reservoirs, DAMS, canals and other projects.
6. Environmental engineering: Used in landfills, sewage treatment plants, etc., to prevent the spread of pollutants.
