Composite Geomembrane for Landfill engineering

Composite geomembrane for landfill is a waterproof barrier material made by heat-laminating HDPE geomembrane with needle-punched nonwoven geotextile. It combines the excellent impermeability of HDPE with the tensile strength, filtration, and protective properties of geotextiles. This product is widely used in municipal solid waste landfills, hazardous waste containment, and industrial waste disposal sites to prevent leachate leakage and environmental contamination.

Main features

  • High physical and mechanical performance indicators: Including tensile resistance, tear resistance, and burst strength.
  • Excellent product characteristics: High strength, good elongation properties, and large deformation modulus.
  • Outstanding material properties: Acid and alkali resistance, corrosion resistance, aging resistance, and superior impermeability.

Purpose

  • Leakage Prevention: Landfill composite geomembranes provide excellent impermeability, effectively containing hazardous waste materials and preventing soil/groundwater contamination.
  • Groundwater Protection: Acts as an efficient barrier layer, blocking harmful substances from infiltrating and preserving groundwater purity for sustainable use.
  • Space Optimization: Enhances landfill capacity by compacting waste volume, reducing land occupation while increasing usable area.
  • Gas Containment: Effectively controls methane and other organic gases generated from waste decomposition, minimizing air pollution emissions.
