Product Overview
Our Long-Filament Geotextile is a premium-grade, nonwoven fabric engineered specifically for
the demanding conditions of mining landfills, tailings storage, and
waste containment systems. Made from high-tenacity polyester or
polypropylene filaments, this geotextile delivers exceptional
filtration, separation, and reinforcement properties, ensuring
long-term stability and environmental protection in harsh mining
environments.
Key Features
Superior Filtration & Drainage
Optimal pore structure allows efficient water flow while retaining fine particles, preventing clogging in leachate collection systems.
High permeability (>1000 L/m²/s) ensures rapid drainage, reducing hydrostatic pressure on landfill liners. Tensile Strength & Puncture Resistance
Reinforced with continuous long filaments for ultimate tensile strength (≥1000 N/m) to withstand heavy loads, sharp rock debris, and mechanical stress during waste compaction.
Resists abrasion and puncture (≥2500 N CBR puncture resistance) for durability in aggressive mining applications.
Chemical & UV Resistance
Inert to acids, alkalis, and heavy metals commonly found in mining waste (e.g., sulfides, cyanide).
UV-stabilized for extended outdoor exposure during installation and service life.
Soil Stabilization & Separation
Prevents intermixing of waste materials and subsoil, maintaining structural integrity of landfill layers.
Enhances slope stability by distributing loads evenly across weak or uneven terrain.
Eco-Friendly & Cost-Efficient
Reduces long-term maintenance costs by protecting geomembrane liners from punctures.
Recyclable material aligns with sustainable mining practices.
