In recent years,with the improvement of China's social and economic level,the construction industry is also developing and innovating technical means,striving to take a more long-term development path,coupled with the residents'architectural planning needs and social construction needs with the economic development and continuous expansion,the corresponding engineering construction quality is also constantly strengthening.In the construction of construction projects,the problem of water seepage prevention has always been one of the key points that the industry attaches great importance to,which will not only affect the performance of the building,but also easily affect the safety and service life of the building.Therefore,in the construction project,we should focus on the problem of water seepage,make a summary of the key points one by one,and put forward comprehensive technical improvement measures in combination with the application of the actual water seepage construction technology.
