Column-point geomembrane for landfill closure is a specialized HDPE material engineered for landfill cap systems. Its unique column-point protrusions create an essential drainage gap between the cap layer and underlying waste, providing superior waterproofing to prevent rainwater infiltration while facilitating efficient surface runoff drainage.

Manufactured from high-density polyethylene (HDPE), this geomembrane offers exceptional resistance to UV radiation, temperature fluctuations, and chemical degradation from landfill gases, ensuring long-term performance in demanding environmental conditions.

This geomembrane is specifically designed for landfill closure and capping projects across various applications:

• Municipal solid waste landfill caps
• Industrial waste landfill closures
• Hazardous waste site remediation projects

As a critical component in landfill cap systems, it combines waterproofing with integrated drainage functionality to significantly reduce leachate formation. The column-point design ensures cap layer stability even as underlying waste settles over time, while supporting vegetation growth for effective ecological restoration of closed landfill sites.

• Enhanced Drainage: Column-point structure facilitates efficient rainwater drainage on landfill caps
• Leachate Reduction: Prevents rainwater infiltration, significantly reducing leachate formation
• Chemical Resistance: Resistant to landfill gases (methane, carbon dioxide) and chemical degradation
• Ecological Support: Supports vegetation growth for ecological restoration of closed landfills
• System Compatibility: Durable construction compatible with other landfill cap components including geotextiles and soil cover
