Geotextile Series

PET Long‑filament Geotextile

PET long‑filament geotextile is made of 100% virgin continuous polyester filament via needle‑punched process. It delivers high tensile strength, superior anti‑aging and anti‑oxidation performance. Mainly used for geomembrane protection, separation, filtration and reinforcement in landfill, reservoir, highway and tunnel projects, gram weight 150‑1200g/m²

PET long‑filament non‑woven geotextile is manufactured from 100% virgin continuous PET polyester filament by advanced needle‑punched consolidation process, without binder additive.Core Advantages
  1. High Mechanical Strength: Superior tensile, tear and CBR burst strength, performs well under heavy‑load engineering conditions.
  1. Excellent Anti‑Aging & UV Resistance: Polyester raw material offers stable performance for long‑term outdoor and buried service, suitable for landfill exposed‑laying sections.
  1. Stable Filtration Property: Uniform pore structure, realizes effective soil retention while allowing free water permeation.
  1. Good Chemical Stability: Resist most soil chemical components, weak acid and alkali corrosion.
  1. No adhesive residue: Needle‑punched only, avoid performance degradation caused by adhesive aging.
Main Functions‑ Protection: Cushion protection layer for HDPE geomembrane against puncture‑ Separation: Isolate different soil and fill layers‑ Filtration: Prevent soil particle loss while draining water‑ Reinforcement: Improve bearing capacity of road and slope foundationTypical Applications‑ Municipal & solid‑waste landfill geomembrane protective layer‑ Reservoir, river bank, artificial lake anti‑seepage project‑ Highway, railway subgrade reinforcement‑ Tunnel, underground works cushion layer‑ Mining environmental restoration projectCommon SpecificationsGram weight：150 g/m² ~ 1200 g/m²；Custom roll width available.Compliance: ASTM D4491, EN 13250 geosynthetic standards.
