In this article, Eugene M. Gallagher et al. describe a series of investigations into the performance of a geomembrane capping at a low level waste repository in the United Kingdom. The investigations took place approximately 25 years after the interim cap installation.
This case history presents the approach, findings, lessons learned, and intervention strategies under consideration for the site. According to the authors, the study “has implications for other landfill caps and highlights the importance of construction processes, including construction quality assurance to ensure the integrity of geomembranes following placement is not adversely affected, also the need for good records management to assess system performance in service and plan future interventions.”
