结合工程实例探讨建筑外墙渗漏的原因及防治措施（Combined with engineering examples, the causes of exterior wall leakage and its prevention measures are discussed） Causes and prevention measures with engineering examples to explore the external wall leakage of buildings Abstract: This paper combined with exterior engineering examples. The possible reasons for the problem of water seepage wall are analyzed, summarized a series of preventive measures. Keywords: exterior wall leakage; leakage; waterproof: material; construction; control measures 1 project overview In the construction of a comprehensive building engineering, building height 97.05m, 1 floor underground and 31 floors on the ground. The podium for a frame shear wall structure, the two main building shear wall structure. 1 layer underground garage, 13 storey office building, 4 to 31 storeys for residential. The total construction area of 45375.62m;. The brick masonry wall slag high-strength insulation block, wall thickness of the skirt building and building were 240mm and 190ram; the foam glass exterior insulation, specifications for 230mmx200mrax20mm. The construction sequence is: exterior wall brick slag high-strength insulation block 1:3 cement mortar crack resistance parameter 5%JX silicon waterproofing agent of a foam glass special polymer adhesive mortar (a foam glass paste of alkali resistant glass fiber mesh cloth in Yin and yang angle corner) a special waterproof anti cracking putty wall waterproof paint. According to the characteristics of the outer wall, in order to avoid and reduce the phenomenon of leakage occurs, firstly, may cause the outer wall leakage reason analysis, and put forward the comprehensive prevention and control measures, to effectively avoid the problem of exterior wall leakage. This paper summarizes the practice, to discuss with colleagues. 2, may cause analysis of exterior wall leakage caused by In 2.1 the material cause of exterior wall leakage (1) the mortar and mortar wall backing is not strictly i
