Advances in Constructional Engineering

As an important part of modern construction technology, the waterproof performance of the exterior wall system of prefabricated buildings directly affects the service life and safety of buildings. This paper conducts an in-depth study on the waterproof technology of the exterior wall system of prefabricated buildings, analyzes the main existing problems, and proposes a series of innovative solutions. Firstly, it explores the key factors affecting the waterproof effect, including material selection, construction technology, and design defects, etc. Then, through case studies, it verifies the practical application effects of different waterproof measures, points out the importance of optimizing the design scheme, and concludes that the use of new waterproof materials combined with scientific and reasonable construction technology can significantly improve the waterproof performance of the exterior wall system.
