Features of Filament Nonwoven Geotextile

High tensile strength, good permeability, air permeability, high-temperature resistance, anti-freezing, anti-aging, corrosion resistance, no – moth. Needle-punched filament nonwoven geotextile is a geosynthetic material widely used. Widely used in railway subgrade reinforcement, road surface maintenance, sports hall, embankment protection, hydraulic construction isolation, tunnel, coastal beach, reclamation, environmental protection, and other projects.

Features Of Filament Nonwoven Geotextile

1. Filtration: When water passes from a fine-grained to a coarsely grained layer, Non-woven Geotextiles can retain fine particles well. Such as when water flows from a sandy soil into a Geotextile wrapped gravel drain.
2. Separation: To separate two layers of soil with different physical properties, such as the separation of road gravel from soft sub-base materials.
3. Drainage: To drain liquid or gas from the plane of the fabric, which leads to draining or venting of the soil, such as the gas vent layer in a landfill cap.
4. Reinforcement: To improve the load bearing capacity of a specific soil structure, such as the reinforcement of a retaining wall.
5. Protective: When the water flows to the soil, will concentrate the stress diffusion effectively, the transmission or the decomposition, prevents the soil to receive the external force action but the destruction, its protection soil.
6. Resistance to puncture: Combined with a geomembrane, the composite waterproof and impermeable material plays a role in preventing puncture.
