Chemically Resistant PET Long Filament Geotextile for Landfill Liners and Heavy Metal Containment Projects

Product Description:
Engineered for the most challenging environmental containment projects, this Long Filament Geotextile serves as a critical component in lining systems for landfills, tailings ponds, and heavy metal treatment sites. Its continuous filament construction provides a high tolerance against the sharp aggregates and harsh conditions found in these applications, primarily functioning as a robust protective layer for geomembranes. The inherent chemical stability of polyester (PET) ensures excellent resistance to a wide range of leachates, acids, and alkalis, preventing degradation over time. Its consistent pore structure also acts as a drainage plane, facilitating the movement of liquids and gases within the composite liner system. By ensuring the integrity of the primary barrier, this geotextile is fundamental to safeguarding the environment from contamination.

Ideal Applications:

• Protection Layer in Municipal and Hazardous Waste Landfills

• Cushioning for Geomembranes in Tailings Impoundments

• Drainage & Filtration Layer in Heavy Metal Containment Sites

• Stabilization Fabric for Acidic or Alkaline Environments like Salt Marshes
