The construction quality of tunnel waterproofing layers directly impacts the long-term stability and service life of tunnels. As a critical component in tunnel construction, quality control of waterproofing layers is particularly vital. This paper provides a detailed discussion on quality supervision during the construction process of tunnel waterproofing layers, proposing control measures from multiple aspects including design, material selection, construction techniques, and inspection methods. By implementing scientific and rigorous supervision management, the quality of waterproofing layer construction can be effectively ensured, preventing issues such as leakage in later stages and guaranteeing safe tunnel operations. Through practical case studies, common quality problems and their prevention strategies are analyzed, offering practical guidance for quality control in tunnel waterproofing layer construction.
