  • Are PVC-P geomembranes degraded in underground application conditions?
  • To analyse the long-term degradation of PVC-P geomembranes in underground application conditions, in this study, a specifically designed accelerated ageing device has been used for the tests. Furthermore, plasticizer absorption tests have been used to estimate the dependence of plasticizer loss on temperature and plasticizer content.
  • What are PVC-P waterproofing geomembranes?
  • Formualtion PVC-P waterproofing geomembranes are composed of 30–40% PVC resin and other additives ( Koerner, 2012), mainly plasticizers. Plasticizers are a group of more than 1000 different polymers used to change the behaviour of PVC from a rigid material to a semi-rigid or flexible one.
  • Are PVC-P geomembranes durable?
  • Currently, the most commonly used technology for tunnel waterproofing is plasticized polyvinyl chloride (PVC-P) geomembranes. However, not much is known about the long-term durability of these geomembranes, especially in relation to the long expected lifespan of new tunnels (i.e. 100–150 years).
  • Does plasticizer loss affect the behaviour of PVC-P geomembranes?
  • Further, to better analyse the influence of plasticizer loss on the behaviour of geomembranes, eight different formulations of PVC-P geomembranes are studied and tested for their mechanical properties. Long-term extrapolations of the ageing of PVC-P geomembranes are estimated on the basis of the plasticizer absorption tests.
  • Does plasticizer loss affect geomembranes in underground applications?
  • In the hypothesis that plasticizer loss is the only degradation process relevant to geomembranes in underground applications, the loss of plasticizer can be evaluated through the loss of weight of the specimens. Accordingly, all the specimens were cleaned, dried in the desiccator for 72 h and weighed before testing.
  • How does a PVC-P geomembrane aging device work?
  • The device accelerates the ageing of the geomembrane in conditions similar to those in underground applications. Two commercial PVC-P geomembranes are tested, and mechanical tests are performed on the aged geomembranes to evaluate the effect of ageing on the properties of the material.
