在建筑工程中,外墙渗漏问题不仅会直接影响居民的正常生活,而且可能导致建筑整体稳定性的下降,影响建筑的使用安全。因此,做好建筑外墙防渗处理,是需要建筑施工人员重点关注的问题。本文对建筑外墙出现渗漏的主要原因进行了分析,并提出了相应的防渗漏施工技术,希望能够为建筑外墙的防渗漏工作提供一些参考。 In construction projects, the problem of external wall leakage will not only directly affect the residents’ normal life, but also may lead to the decline of the overall stability of the buildings and the safety of the buildings. Therefore, to do a good job of impermeable exterior wall construction, construction workers need to focus on the issue of concern. In this paper, the main causes of seepage on the exterior wall of the building are analyzed, and the corresponding anti-seepage construction technology is put forward, hoping to provide some references for the anti-seepage work of the exterior wall.
