ABSTRACT: This paper presents the findings of a series of large-scale laboratory trials with the purpose of evaluating the leakage rate through a defect in a geomembrane used as a cover for a mine waste rock pile. Preliminary results were presented at GeoCalgary 2022 for leakage rates through a defect in an exposed geomembrane cover. This paper provides follow-up data for leakage rates through a defect in a geomembrane cover system, which included a drainage geocomposite and a cover soil overlying the geomembrane. The cover system was tested in a large-scale hillslope apparatus that allowed for control of slope angle and precipitation rate. The leakage rate was assessed for different sizes, shapes, and locations of defects.
