Staple Geotextile Effective In Preventing Pollutant Spread In
Environmental Projects
Product Introduction
Staple fiber geotextile is a kind of geosynthetic material made by
non-woven production equipment with short fiber as raw material,
and has good filtration performance.
Product Properties
1. Filterability: Staple fiber geotextiles have good filtration
performance, which can prevent the loss of fine soil particles
while allowing the flow of water. When the water flows from the
fine soil layer into the coarse soil layer, the staple fiber
geotextile can effectively intercept the soil particles, fine sand,
small stone, etc., and maintain the stability of soil and water
engineering.
2. Water permeability: The staple fiber geotextile has high water
permeability and can maintain good water permeability even under
the pressure of soil and water.
3. Corrosion resistance: staple fiber geotextile with polypropylene
or polyester and other chemical fiber as raw materials, acid and
alkali resistance, no corrosion, no moth, anti-oxidation.
4. Durability: Staple fiber geotextile has high tensile strength
and deformation resistance, which can enhance the stability of
soil.
5. Easy construction: short fiber geotextile light weight, easy to
use, simple construction.
Product Application
1. Water conservancy projects: In reservoirs, DAMS, canals and
other projects, 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.
