Polyester Filament Nonwoven Geotextile

Good water permeability, and anti-corrosion, anti-aging, isolation, anti-filtration, drainage, protection, stabilization, reinforcement and other functions, can adapt to the uneven grass-roots level, can resist the construction of external damage, creep is small, long-term load can still maintain the original function.

Filament geotextile is a new type of construction material used in civil engineering, which is made of filament fibers arranged into a mesh through different equipments and crafts, and then through needle punching and other crafts to let different fibers intertwine with each other, entangling and fixing each other to make the fabric specification, so that the fabric is soft, plump, thick and hard to meet the use of different thicknesses, and the filament geotextile has a good mechanical function, good water permeability, corrosion resistance, anti-aging, isolation, anti-filtration, drainage, protection, stabilization, reinforcement and other functions, which can adapt to the uneven grass-roots level, and can resist the damage of construction. Good water permeability, and anti-corrosion, anti-aging, isolation, anti-filtration, drainage, protection, stabilization, reinforcement and other functions, can adapt to the uneven grass-roots level, can resist the construction of external damage, creep is small, long-term load can still maintain the original function.

Product properties of filament geotextile

The product is characterized by high strength, anti-aging, acid and alkali resistance, abrasion resistance, good flexibility and easy construction.

1, does not contain chemical additives, is an environmentally friendly building materials

2, has good mechanical properties, good water permeability, and can resist corrosion, anti-aging

3, has a strong anti-burial, corrosion-resistant properties of the structure of the fluffy, with good drainage properties

4, has a good coefficient of friction and tensile strength, with geotechnical reinforcing properties

5, with isolation, anti-filtration, drainage, protection, stabilization, strengthening and other functions

6, can adapt to the uneven grass-roots level, can resist the construction of external damage, creep is small.

7, good overall continuity, light weight, convenient construction

8, for the permeable material, so it has a good anti-filtration isolation function, strong puncture resistance, so it has a good protection performance.

◆ Utilizing filament geotextile's good air permeability and water permeability, make water flow through, so as to effectively intercept sand and soil loss; ◆ Filament geotextile has good air permeability and water permeability, so as to effectively intercept sand and soil loss.

◆ The filament geotextile has good water-conducting property, it can form a drainage channel inside the soil body, and the excess liquid and gas will be discharged out of the soil structure; ◆ The filament geotextile can strengthen the soil structure, so it has good protection property.

◆ Use geotextile to enhance the tensile strength and deformation resistance of the soil body, enhance the stability of the building structure to improve the quality of the soil body.

◆ Effectively spreading, transferring or decomposing the concentrated stress, preventing the soil body from being damaged by external force; ◆ Preventing the upper and lower layers of sand and gravel from being damaged by external force.

◆ Prevent mixing between upper and lower layers of gravel, soil and concrete.

◆ The mesh is not easy to be blocked because the mesh structure formed by indeterminate fiber organization has strain and movement.

High water permeability Under the pressure of soil water, it can still maintain good water permeability.

◆ Corrosion-resistant With polypropylene or polyester and other chemical fibers as raw materials, acid and alkali resistant, non-corrosive, non-insect, anti-oxidation; ◆ Advantages Light weight, easy to construct.

◆ Advantages Light weight, simple construction, easy to use, shorten the construction period, improve economic efficiency, and prolong the project life cycle.
