The adaptability of geomembranes, combined with their economic viability, makes them a popular choice for environmental engineers seeking to mitigate environmental issues.

High-Performance Geomembranes for Landfill Liner Systems

Landfill liner systems are critical components in modern waste management strategies. These primary function is to prevent the migration of harmful contaminants from landfill waste into surrounding groundwater. To effectively achieve this, high-performance geomembranes have emerged as a vital material for constructing robust and reliable liner systems. Such geomembranes are engineered with superior physical properties to withstand the demanding conditions found within landfills.

Geotextiles are typically manufactured from flexible polymer materials such as high-density polyethylene (HDPE) or polyvinyl chloride (PVC). They exceptional flexibility allows them to conform to the complex geometry of landfill sites, providing a continuous and impermeable barrier. Moreover, geomembranes exhibit excellent resistance to degradation from the harsh environmental factors present in landfills.
