Product Overview
Our Long-Filament Geotextile is a heavy-duty, nonwoven fabric engineered exclusively for industrial waste landfill applications. Designed to endure aggressive chemical exposure, high mechanical stress, and long-term environmental challenges, this geotextile provides critical filtration, separation, and reinforcement functions. It ensures the structural stability of landfill layers, prevents contamination, and safeguards ecosystems from hazardous waste leachate.

Key Features

1. Exceptional Filtration & Drainage

   • Engineered pore structure ensures optimal permeability (>1200 L/m²/s) while retaining fine particles, preventing clogging in leachate collection systems.

   • Facilitates rapid drainage to reduce hydrostatic pressure on geomembrane liners.

2. Ultra-High Tensile & Puncture Resistance

   • Reinforced with continuous polyester/polypropylene filaments for unmatched tensile strength (≥1200 kN/m) to withstand heavy waste loads, sharp debris, and compaction machinery.

   • CBR puncture resistance ≥3000 N (ASTM D6241), ideal for abrasive industrial waste materials.

3. Chemical Inertness

   • Resists acids, alkalis, hydrocarbons, and heavy metals (e.g., lead, arsenic) commonly found in industrial slag and waste streams.

   • UV-stabilized for prolonged outdoor exposure during installation and service life.

4. Soil Stabilization & Layer Separation

   • Prevents intermixing of waste and subsoil, maintaining landfill integrity and preventing subsidence.

   • Enhances slope stability by distributing loads evenly across unstable substrates.

5. Eco-Conscious Design

   • Protects geomembranes from punctures, extending liner lifespan and reducing landfill maintenance costs.

   • Recyclable material supports sustainable waste management practices.

Why Choose Our Geotextile?
✅ Landfill-Specific Engineering: Optimized for extreme chemical and mechanical demands of industrial waste.
✅ Long-Term Reliability: 30+ year service life under harsh UV, chemical, and load conditions.
✅ Custom Configurations: Choose needle-punched, heat-bonded, or composite designs for enhanced friction or filtration.
✅ Global Compliance: Meets EPA, EU Landfill Directive, and ISO 9001/14001 standards.

Installation Best Practices

1. Subgrade Preparation: Level and compact soil; remove sharp objects to avoid fabric damage.

2. Roll Deployment: Unroll geotextile with 300–600 mm overlaps; secure with staples or adhesive.

3. Seam Integrity: Stitch or thermally bond overlaps in high-stress zones (e.g., slopes, joints).

4. Protection Layer: Immediately cover with drainage aggregate or soil to prevent UV degradation.
