PET Geotextile: A High-Performance Geosynthetic Material for Diverse Engineering Applications

Material Properties

• Composition: Woven/nonwoven polyester fibers

• Key Advantages:

• Tensile strength: 20-100 kN/m

• UV resistance: ≥70% strength retention after 2000 hrs exposure

• Chemical stability: pH 2-12 compatibility

Engineering Applications

1. Road Construction

• Subgrade Reinforcement

• Increases bearing capacity by 30-50%, reducing differential settlement.

• Typical installation: Between subbase and base layers (150-300g/m²).

• Reflective Crack Mitigation

• Reduces asphalt pavement cracking by 60-80% when placed under overlay.

• Slope Protection

• Erosion control on 1:1.5 to 1:2 slopes with vegetation compatibility.

2. Hydraulic Engineering

• Dam Construction

• Core waterproofing (with geomembranes) achieving permeability<10⁻¹⁰ m/s.

• Prevents piping failures under 50m+ hydraulic heads.

• Canal Linings

• Saves 15-30% water loss versus unlined channels.

3. Railway Infrastructure

• Track Bed Separation

• Maintains ballast porosity (>35%) while preventing fines migration.

• Extends maintenance cycles by 2-3x.

4. Waste Containment

• Landfill Systems

• Filtration (O₉₀<0.075mm)

• Protection against geomembrane puncture

• Dual-function in composite liners:

5. Mining Operations

• Tailings Management

• Enhances consolidation rates by 40% through controlled drainage.

• Withstands 200kPa+ static loads in stackable designs.

6. Environmental Projects

• Water Treatment

• Filtration efficiency: 95% TSS removal at 10L/m²/s flow rates.

• Ecological Restoration

• Supports plant growth while containing contaminants (heavy metal retention >90%).
