Environmental-Friendly Staple Geotextile for Landfill Covers
Product Introduction
Staple fiber geotextile is a geosynthetic material made of short fibers by physical methods (such as acupuncture, chemical bonding, etc.). It is widely used in civil engineering.
Product Properties
1. Road construction and maintenance: as a reinforcement material of the base layer, improve the bearing capacity and durability of the road.
2. Hydraulic engineering: used as filtration and drainage materials in reservoirs, canals, DAMS and other projects.
3. Environmental engineering: Covers used in landfills to prevent waste from coming into direct contact with soil.
4. Foundation reinforcement: Provides reinforcement on weak foundations to increase the carrying capacity of the soil.
5. Slope engineering: used for slope protection and stability, to prevent erosion and landslide.
6. Tunnel engineering: plays the role of strengthening and waterproofing in the tunnel lining.
Product Application
1. Road construction: improve the carrying capacity of roads and extend the service life of roads.
2. Hydraulic engineering: used for reinforcement and filtration in reservoirs, DAMS, canals and other projects.
3. Environmental engineering: Used in landfills, sewage treatment plants, etc., to prevent the spread of pollutants.
4. Civil engineering: Used as reinforcement and isolation materials in the construction of tunnels, subways, airports and other infrastructure.
5. Slope engineering: Used for slope protection to prevent soil erosion and landslides.
