Ultra-Low Permeability HDPE Geomembrane 1×10⁻¹⁷ cm/s Anti Seepage for Hazardous Waste Landfill Zero Leakage Containment

Ultra-Low Permeability HDPE Geomembrane - 1*10⁻¹⁷ cm/s

With an impermeability coefficient of ≤1*10⁻¹⁷ cm/s, this HDPE geomembrane provides the ultimate barrier against liquid and gas migration. This extremely low permeability meets the most stringent environmental regulations for hazardous waste containment, ensuring zero leakage into surrounding soil and groundwater.

Barrier Performance

• Hydraulic conductivity: ≤1*10⁻¹⁷ cm/s (ASTM D5887)
• Water vapor transmission: <0.01 g/m²/day
• Methane gas transmission: extremely low barrier
• Effective barrier for VOCs and SVOCs
• Chemical compatibility with leachate constituents

Critical Applications

Hazardous waste landfill cells, nuclear waste interim storage, chemical plant secondary containment, contaminated site remediation caps, and groundwater protection barrier systems requiring maximum impermeability.
