Polyester Continuous Filament Nonwoven Geotextile, also called PET filament geotextile, is produced with 100% virgin polyester PET chips via melt-spun, laid-web and high-density needle punching technology. Formed by endless continuous filaments without broken short fibers, it owns outstanding tensile, tear and puncture resistance, stable filtration void structure. It integrates separation, filtration, drainage, protection and reinforcement functions, widely matched with HDPE geomembrane, drainage board, geogrid for highway, railway, landfill, tunnel, hydraulic and municipal projects worldwide.
Core Product Features
Manufactured with anti-aging additives, fully compliant with GB/T 17639-2023 and international ASTM standards, core advantages as below:
- Superior Mechanical Strength & Low Creep Continuous long fiber interlocking structure delivers far higher tensile, trapezoidal tear and CBR puncture strength than staple fiber geotextile. Stable fiber structure brings tiny long-term creep, suitable for permanent heavy-load geotechnical reinforcement projects.
- Stable Filtration & Anti-Clogging Performance Uniform pore size distribution (AOS 0.07–0.20mm). Permits free water outflow while intercepting fine soil particles, effectively avoiding drainage channel blockage in long-term underground service.
- Excellent Chemical & Microbial Resistance PET polyester is inert to acid, alkali, salt, landfill leachate and industrial wastewater within pH 2–13. Resists mildew, insect and microbial erosion, no hydrolysis degradation under long-term wet burial conditionsAlibaba.co....
- Outstanding UV & Weather Aging Resistance Superior light stability among geotextile fabrics. With anti-UV formulation, outdoor exposed projects retain over 70% original strength after 500h UV accelerated test, long service life for slope and coastal projects.
- Multi-Functional Protective Cushion Layer Soft and tough texture works as buffer between geomembrane and sharp gravel, effectively preventing puncture damage to HDPE liner; widely used as composite geotextile for one-piece anti-seepage system.
- Lightweight & Easy Construction Wide roll width up to 6m reduces joint overlap, easy to cut, lay and overlap on site. Flexible for slope, vertical wall and curved structure laying, greatly shorten construction cycle.

Wide Application Scenarios
1. Highway & Railway Engineering
Roadbed separation & reinforcement, soft ground treatment, slope erosion control, bridge abutment backfill, anti-reflection crack layer between pavement and subbase. Separates soil and aggregate to prevent intermixing and uneven settlement.
2. Environmental Solid Waste & Mining Projects
Municipal landfill liner protective cushion, leachate drainage layer, tailings pond lining protection, heap leach pad filtration. Protect HDPE geomembrane from sharp stone puncture, stabilize drainage system.
3. Hydraulic & Water Conservancy Works
Reservoir, river, canal, seawall, dam core filtration layer, artificial lake anti-seepage cushion, coastal revetment erosion control. Drain groundwater while retaining soil to prevent bank collapse.
4. Tunnel & Underground Municipal Engineering
Subway, highway tunnel lining drainage layer, underground garage roof drainage, foundation pit waterproof protection, comprehensive pipe gallery filtration. Release hydrostatic pressure and avoid underground water seepage.
5. Landscape & Aquaculture Projects
Roof garden, vertical greening, football field drainage layer, fish/shrimp pond liner protection, park rainwater infiltration system. Maintain soil permeability and prevent root rot caused by waterlogging.
Five Core Engineering Functions
- Separation: Isolate different soil/aggregate layers, maintain independent structural performance.
- Filtration: Permeate water, block fine soil particles, prevent soil loss and channel clogging.
- Drainage: Form horizontal water flow channel to rapidly discharge excess groundwater.
- Protection: Cushion geomembrane and concrete from scratch, puncture and impact damage.
- Reinforcement: Uniformly distribute soil stress, improve overall stability of soft foundation and slope.
Product Classification
- Standard White Polyester Filament Geotextile General underground engineering grade, balanced strength and cost, for landfill, tunnel, reservoir, road base.
- UV-Stabilized Black Filament Geotextile Added carbon black anti-UV agent, specially for outdoor exposed slope, coastal embankment and long-term open-air projects.
