400gsm Pet Continuous Filament Polyester Nonwoven Geotextile For Civil Engineerings
Polyester filament geotextile is a non-woven geosynthetic material made of polyester chips (PET) through spinning, laying nets, needle punching and other processes. Its performance is better than that of short-fiber geotextile and is widely used in the field of civil engineering.
Product Overview
Raw Materials and Process
Polyester filament geotextile is made of polyester chips through melt spinning, air-laid web and needle punching reinforcement process to form a three-dimensional pore structure. Compared with staple geotextile, its fiber arrangement is more uniform, and new materials are used in the production process without recycled materials.
Main Features
· High strength: The tensile strength is significantly higher than that of staple geotextile, especially suitable for high-load scenarios.
· Corrosion resistance: Acid and alkali resistant, aging resistant, adaptable to complex geological environments.
· Water permeability: The three-dimensional structure achieves efficient drainage and has anti-filtration function.
· Thermal stability: High temperature resistance (-60℃~120℃), good flexibility.

Key application scenarios
1. Water conservancy projects
· Anti-filtration layer of dams and slope protection to prevent soil erosion.
· Component of river regulation and anti-seepage composite layer of artificial lakes.
2. Transportation infrastructure
· Isolation and reinforcement of highway/railway subgrade to delay reflective cracks.
· Drainage of airport runway foundation to enhance foundation stability.
3. Environmental protection projects
· Anti-seepage and isolation of landfills and waste liquid treatment plants.
· Anti-scour protection layer in coastal beach reclamation.
Technical parameters and construction points
1. Specifications
·Weight range: 100~1000g/㎡ (commonly used 150~800g/㎡).
·Size: width 2~6 meters, length 50~100 meters (customizable).
2. Construction specifications
·Laying method: buried in the soil, covering thickness ≥30cm; overlap width ≥20cm, sutured or hot welded.
·Edge treatment: fixed with sandbags or wire to avoid displacement.
·Quality control: damage needs to be checked after construction, and patches of the same material should be used for repair.
Purchase suggestions
·Prefer high-strength filament products to avoid mixing with short fibers.
·Composite anti-seepage projects must be used with geomembranes, and the permeability coefficient must be ≤10⁻¹¹m/s.
