Short fiber needle punched non-woven geotextile

① Product Introduction:

Short fiber needle punched geotextile is made of polyester or polypropylene short fibers that are needle punched and consolidated. The fibers are arranged in a three-dimensional structure, entangled and intertwined, and have good mechanical properties that are uniform in all directions. At the same time, it has good longitudinal and transverse drainage performance, excellent elongation performance, and high chemical stability such as biological, acid and alkali resistance, and aging resistance. At the same time, it also has a wide range of pore sizes, a tortuous pore distribution, excellent permeability and filtration performance.

② Product features:

1) High strength, due to the use of plastic fibers, it can maintain sufficient strength and elongation in both dry and wet conditions.

2) Corrosion resistance, able to withstand corrosion for a long time in soil and water of different pH levels.

3) Good permeability is due to the presence of gaps between fibers, resulting in excellent water permeability.

4) Good resistance to microorganisms and insect infestations without damage.

5) Easy to construct, due to its lightweight and flexible material, it is convenient for transportation, laying, and construction.

6) Complete specifications: The width can reach up to 7 meters. Unit area mass: 100-1000g/m ²

③ Application scope:

1) Road surface maintenance for highway and bridge engineering Reinforcement; Protection, reinforcement, and prevention of reflection cracks in the renovation of old roads.  

2) Foundation treatment and roadbed drainage for high-speed railways, expressways, and high-grade highways Frost heave soil treatment and salt prevention, slope erosion prevention, applied to reinforced layers, isolation layers, cement stabilized layers: tunnel protection, isolation, and drainage.

3) Reinforcement, isolation, and protection of the bottom, slopes, and sealing of environmental protection projects such as landfill sites, oil storage tanks, and ash yards.

4) Anti filtration of hydraulic engineering embankments and slope protection: isolation and anti-seepage of hydraulic channels, river management, and artificial lakes.

5) The foundation isolation, filtration, drainage, soil slope, retaining wall, and pavement reinforcement and drainage of highways, railways, road construction, buildings, and airport runways.

6) Soft foundation treatment for port engineering, reinforcement and drainage of beach embankments, harbor docks and breakwaters.
