Staple Geotextile Durable and Corrosion-Resistant for Environmental
Engineering
Product Introduction
Staple fiber geotextile is a kind of geomaterial with good water
permeability, which is widely used in civil engineering.
Product Properties
1. Water permeability: water permeable short fiber geotextile has
good permeability and water permeability, can make water flow
through, while effectively intercepting soil particles, fine sand,
small stone, etc., to maintain the stability of soil and water
engineering.
2. Filterability: When water flows from the fine soil layer into
the coarse soil layer, the permeable staple fiber geotextile can
play a filtering role to prevent soil loss.
3. Durability: It has good tensile strength and deformation
resistance, which can enhance the stability of the building
structure.
4. Corrosion resistance: can resist the erosion of a variety of
chemical substances, suitable for different environmental
conditions.
Product Application
1. Water conservancy projects: In reservoirs, DAMS, canals and
other projects, permeable staple fiber geotextiles are used for
reinforcement and filtration.
2. Road construction: improve the bearing capacity and stability of
the roadbed, extend the service life of the road.
3. Environmental engineering: Prevent the spread of pollutants in
landfills, sewage treatment plants and other projects.
4. Slope engineering: Used for slope protection to prevent soil
erosion and landslides.
