Landfill liner systems are complex assemblies designed to contain waste and collect leachate for treatment. Heavyweight nonwoven geotextile, typically ranging from 300 to 1200 g/m², is placed directly above geomembranes to provide cushioning and puncture protection from overlying drainage stone or waste materials . This protection function is critical, as even small punctures can compromise the entire containment system.
In leachate collection layers, geotextile filter fabric surrounds drainage pipes and aggregate, allowing liquids to flow freely while preventing soil and waste particles from entering and clogging the system. The filtration performance must be maintained over decades, requiring careful specification based on site-specific waste and leachate characteristics .
Geocomposites combining geotextile with drainage cores or geonets provide efficient leachate collection and detection layers within landfill designs. These factory-fabricated products offer consistent performance and simplified installation compared to separate component placement. At www.hzgeotextile.com, our landfill geotextiles are manufactured to meet rigorous chemical resistance and long-term performance requirements, ensuring environmental protection for generations.
