Long Filament Woven Geotextile

Strength in Every Strand – Reinforcing Megastructures for Generations

Product Overview

Manufactured from high-tenacity polyester (PET) continuous filaments via precision-oriented weaving technology, this geotextile delivers unparalleled tensile strength, dimensional stability, and long-term durability. Engineered for critical permanent infrastructure, it serves as a core reinforcement material for high-speed railways, airports, seaports, and other heavy-load projects.

Key Performance Advantages

1. Extreme Tensile Strength

   • Longitudinal/Transverse Strength: ≥30~150 kN/m (industry-leading), with high modulus and low creep for sustained heavy-load resistance.

2. Century-Scale Service Life

   • UV Resistance Grade ≥Class 8 (GB/T 17630), resistant to chemicals, microorganisms, and biodegradation. Service life ≥100 years in buried conditions.

3. Precision Filtration Control

   • Uniform Aperture (0.08~0.3mm), Permeability ≥2.0×10⁻² cm/s, enabling optimal soil-water separation without clogging.

4. Superior Damage Resistance

   • Burst Strength ≥5.0 kN, High Friction Coefficient (≥0.8), resistant to installation abrasion and ground deformation.

Premium Applications

⚡ Heavy-Load Transport: Ballastless high-speed rail subgrades, airport runway base reinforcement
🌉 Marine Structures: Breakwater core stabilization, deep-water quay revetment layering
🏗️ Permanent Slopes: Mine rehabilitation embankments, nuclear containment cofferdams
🚄 Settlement-Sensitive Zones: Bridge abutment settlement control, 3D soft-soil reinforcement
🛟 Disaster Prevention: Debris flow barriers, rockfall containment meshes

Jiantong’s Excellence Commitment

• Ultra-Premium Material: 100% virgin PET filaments (EU REACH compliant), tensile strength ≥7.0 cN/dtex.

• Advanced Weaving: Produced on Germany’s Monforts wide-width looms. Custom seamless widths: 2~8m; precise warp-weft density control.

• Rigorous Certification: Dual compliance with GB/T 17639-2008 & ISO 10318. Tested via UV aging chambers, dynamic perforation testers.

• Engineering Intelligence: Structural calculations, BIM-based installation simulations, and lifecycle maintenance protocols.

Installation Protocol

Deploy under pre-tension (elongation ≤2%). Seams require high-strength sewing (strength retention ≥85%) or thermal bonding. UV exposure beyond 14 days mandates protective covering.
