Abstract:The anti-seepage and anti leakage work of the basement in high-rise buildings is crucial to ensure the safety and functionality of the entire building structure. With the acceleration of urbanization and the increase in underground space utilization, the number of high-rise buildings is increasing, which makes the waterproof and moisture-proof technology of basements an important consideration factor in building design and construction. This article discusses the relevant seepage and anti leakage construction techniques from several aspects, including common diseases, causes, and treatment methods of basement leakage. Taking a high-rise building in Macau as an example, the key technologies of basement waterproofing construction are introduced in detail.
