Abstract: The last three decades have brought tremendous improvements to quality control (QC) procedures for construction and post-construction verification of deep cutoff walls installed in active high-hazard dams. Developments have been made in every aspect of the construction processes, including drilling/excavation, cleaning of inter-element joints, preparation and placement of backfill materials, verification of the constructed product, and data collection, representation, and monitoring of dam instrumentation.
