Classification :
PRODUCT DETAILS
1.The Ultimate Solution for Road Subgrade Stabilization and Durability
Why Choose PET Filament for Road Reinforcement?
Our High Strength PET Filament Nonwoven Geotextile is engineered specifically to meet the stringent demands of modern infrastructure projects, particularly in road, railway, and highway construction. Unlike conventional staple fiber textiles, our product utilizes continuous PET filaments that are needle-punched and thermally bonded, resulting in a fabric with exceptional mechanical and hydraulic properties.
2.Key Performance Advantages:
-
Superior Tensile Strength: Provides the highest level of reinforcement, crucial for transferring loads across weak soil foundations and ensuring subgrade stabilization.
-
Minimal Creep (Low Creep): The high melting point and inherent properties of PET filaments result in extremely low creep deformation under long-term, heavy loads, guaranteeing the longevity of permanent structures like roads and railways.
-
Excellent Puncture Resistance: Offers a robust separation layer, effectively preventing the intermixing of base aggregate and soft subgrade soil, protecting the integrity of the pavement structure.
-
High Flow Rate Filtration: Functions as an effective filter, allowing water to pass through rapidly while retaining fine soil particles, preventing drainage systems from clogging.
-
UV and Chemical Resistance: Maintains performance integrity in various soil types and exposure to construction chemicals, extending the service life of the road infrastructure.
3.Core Functions in Road and Infrastructure Projects
The versatility of our PET Filament Geotextile makes it indispensable for numerous civil engineering challenges:
-
Subgrade Separation & Stabilization: Used beneath access roads, main highways, and railways to provide a stable platform over weak or inconsistent soils.
-
Pavement Overlay: Applied in asphalt pavement reconstruction to absorb stress and mitigate reflective cracking, prolonging the pavement's service life.
-
Filtration and Drainage: Acts as a crucial filter layer in trench drains, French drains, and around sub-surface drainage pipes, ensuring efficient water removal from the roadbed.
-
Embankment and Slope Reinforcement: Provides structural strength for steep slopes and road embankments, enhancing overall stability and preventing erosion.

Related Geosynthetic Materials
Geotextiles play a fundamental role when integrated with other geosynthetic materials to ensure long-term structural integrity in various engineering projects. In many civil applications, these fabrics are often paired with high-performance geomembranes to provide both mechanical protection and effective fluid containment. For instance, using a non-woven geotextile as a protective cushion for an HDPE geomembrane significantly reduces the risk of liner punctures in landfill or mining sites. In specific scenarios where a pre-bonded solution is required, a composite geomembrane offers the integrated benefits of both filtration and impermeability. Selecting the appropriate material combination is essential for meeting rigorous international standards and ensuring the durability of the infrastructure. Our technical team is ready to help you determine the optimal material configuration for your specific environmental and construction needs.

Geotextiles FAQs
1) What are geotextiles used for?
Geotextiles primarily serve five key functions: separation, filtration, drainage, reinforcement, and erosion control. They are widely utilized in highway subgrade reinforcement, railway construction, the encapsulation of retaining wall backfill, riverbank protection, and basement drainage systems, thereby extending the service life of engineering projects and reducing maintenance costs by optimizing soil structure.
2) What's the difference between woven and nonwoven geotextiles?
The fundamental difference lies in their functional emphasis: Woven geotextiles are fabricated by weaving fibers and possess high tensile strength, making them suitable for heavy-load applications such as soft ground reinforcement and embankment engineering. Non-woven geotextiles, produced via a needle-punching process, exhibit superior permeability and are primarily utilized for drainage in blind drains, filtration behind retaining walls, and the protection of impermeable membranes.
3) How do I choose the right geotextile (GSM/oz, permittivity, AOS)?
Engineers typically select materials based on five key metrics—basis weight (GSM/oz), Apparent Opening Size (AOS), water permeability, tensile strength, and CBR puncture strength—to ensure the material meets the project's load-bearing and drainage requirements.
4) Can geotextiles be used for drainage and filtration together?
Yes, needle-punched non-woven geotextiles possess excellent composite properties. Acting as a filtration layer, they prevent the loss of fine soil particles; simultaneously, their internal three-dimensional structure efficiently channels and drains water in the planar direction. Consequently, they are widely utilized in various underground anti-siltation and drainage systems.
5) Do geotextiles meet common standards (ASTM/ISO) and how do you provide QA?
Our products strictly adhere to international ASTM and ISO standards. We maintain oversight through a comprehensive, end-to-end QA/QC system; prior to shipment, every product batch undergoes rigorous testing for tensile strength, pore size, and water permeability, accompanied by third-party inspection reports. Furthermore, we offer customized R&D services to meet specific mechanical performance requirements based on engineering drawings.
