Polyester filament nonwoven geotextile is a kind of highperformance geosynthetics made of highstrength polyester (PET) filament, processed by advanced spunbonding and needlepunching technology. It has excellent mechanical properties, chemical resistance, aging resistance and good water permeability and filtration, and is widely used in civil engineering, water conservancy engineering, transportation infrastructure, environmental protection engineering and other fields, and is one of the indispensable basic materials in modern engineering.

Product Characteristics 

1. High Strength and Durability 
Adopting high strength polyester filament, high tensile strength and low elongation, it can effectively withstand the loads in construction and use.
Resistant to acid and alkali, ultraviolet rays and aging, it can adapt to the complex environment, with a service life of more than 50 years.

2. Excellent filtration and drainage performance 
Threedimensional mesh fiber structure forms a good permeable channel, effectively isolating soil particles, preventing soil erosion, while ensuring smooth water flow.

3. puncture resistance and protection 
The dense structure formed by the needlepunching process can resist the puncture of sharp objects and protect the waterproof layer or the underlying structure from damage.

4. environmental protection and stability 
material is nontoxic and harmless, in line with environmental standards; good thermal stability, to adapt to the 60 ℃ to 120 ℃ temperature range.

5. Convenient construction 
Light weight, coil packaging, easy to transport; can be cut or sewn according to demand, to adapt to a variety of engineering scenarios.

Technical Parameters

Product Advantages 

Economical and efficient: prolong project life and reduce maintenance cost.

Multifunctionality: both isolation, reinforcement, filtration, protection and other functions.

Quality control: standardized testing from raw materials to production to ensure stable performance.

Suggestions for use 

Clean up the grassroots level before laying to ensure that it is flat and free of sharp objects.

The lap width is recommended to be 10~15cm, and can be reinforced by stitching or bonding.

Select the appropriate weight and technical specifications according to the project requirements.

Packaging and Storage 

Packed in rolls with PE film to prevent moisture and dust. (Customized packaging is available)
