  1. WorkshopThe Service Life of Geomembrane Liners Chairman: Adrian Needham Panel: Bob Koerner Vladimir Nosko Ian Peggs

  2. Controlling Factors (1) • Quality of design • Material selection • Avoidance of tensile stresses • Slope stability and subgrade integrity • Adequate protection to liner • In landfills, waste settlement effects • Thorough site-specific specification • Do not make the installers job difficult!

  3. Controlling Factors (2) • Physical damage • Vulnerable to damage at all stages • Material degradation • Oxidation, UV, aggressive chemicals • Stress cracking ( mainly HDPE)

  4. Regulatory Requirements • How long is the required design life? • Many applications, different countries • UK landfill requirements • No fixed period • Until the waste stabilises and is not a pollution hazard to environment • Hundreds, even thousands, of years • Long term durability of geomembranes critical
