Abstract: This research aims to explore the scientific application of waterproofing and seepage prevention technologies in construction projects, providing references for enhancing the durability and safety of buildings. Starting from the problems such as structural damage, functional failure and economic loss caused by building leakage, the necessity of applying this technology is clarified. By adopting the classified research method, the causes of leakage in areas prone to leakage such as basements, roofs, exterior walls, and kitchens and bathrooms are analyzed. It details the key points of suitable waterproofing and anti-seepage technologies, proposes solutions, and strictly controls details across design, material selection, construction, and management stages, emphasizing inspection and acceptance to prevent leakage risks. Based on engineering cases, it can be known that the reasonable application of this technology can reduce the leakage rate by more than 60% and significantly improve the structural stability. However, there are still problems such as uneven material quality, non-standard construction, and lack of later maintenance. Based on this, solutions such as optimizing material selection, strengthening construction control, and establishing maintenance mechanisms are proposed. At the same time, it is pointed out that the research does not cover the technical adaptability in special climate regions, and further research can be expanded in the future.
