by What should I do if it leaks after the five-year warranty period? Should this pot be carried in an assembled structure? What do you think of the standard inspection, so that every engineer can have a fair understanding! standard.
We all know that it is a temporary solution rather than a permanent solution.
Hello, everyone.
Soon after the first batch of residents were decorated and moved in, water seepage occurred on the walls of hundreds of residents’ homes in the typhoon season, resulting in a lot of losses.
Mr.
The preliminary plan adopted by the developer is to apply waterproof glue outside.
The process was not mature at that time and was vigorously promoted; Therefore, gaps appear at the joints of wallboards and other parts.
At present, the developer has carried out pilot leakage repair on two exterior walls under the guidance of relevant functional departments, technical departments and design institutes in accordance with the guidelines for the quality management of waterproof technology of assembled integral concrete buildings in Shanghai issued by Shanghai Municipal Commission of housing and urban rural development in March 2020.
At that time, the development of this process was not mature enough, and there were deviations in the preliminary operation and design, resulting in the emergence of water leakage.
It is also different from the multi mortar joint wall built with small bricks, which is easy to release stress.
Recently, a large area of exterior wall seepage occurred in * * Yiyuan community, Miaoqiao Road, Kangqiao Town, Pudong New Area, Shanghai, resulting in the waste of interior decoration.
Therefore, the developer has adopted the process of drilling holes and injecting glue on the leaking wall to enhance the waterproof capacity of the wall.
said it had repaired more than 170 households for water seepage.
It is expected to start next week, and the maintenance cost is about 6 million.
But the developer said it was difficult.
The community construction unit said that the community is the first batch of communities constructed by assembly technology in the new area.
Therefore, in addition to paying special attention to safety, precast shear wall structure should also pay attention to water seepage, and relative measures should be taken in design or construction.
I’m uncle Cha, the editor in chief of normative Cha, and an engineer with attitude.
But when typhoon fireworks came this year, water seepage appeared on the repaired wall again.
It will still leak after a rainy season ▲ the deep and shallow marks are all water leakage points.
This community is the affordable housing delivered in May 2020.
Precast shear wall is different from cast-in-situ shear wall, and there is a joint problem.
Residents heard this reason fried the pot and asked the developer to completely repair the joint gap.
Developer: the repair scheme can ensure no leakage for 5 years.
After the water spraying and wind resistance test, plus the test of a typhoon, the final waterproof implementation scheme has been determined.
In order to meet the needs of assembly rate, many houses now adopt precast shear wall structure.
Such repair may cost hundreds of millions of yuan.
Shen made it clear: “the repair plan will certainly ensure that there will be no leakage within 5 years.” The service life of this house is 70 years.
Friends who pay new attention will get 500 standard meeting gifts! The developer explained that the reason for the leakage was that a new “assembly” process was adopted during the construction of the community five years ago.

The project will be started in December 2016 and completed in April 2019, and will be delivered in May 2020; Residents said that about 400 people reported to the property for repair, while the community property management Co., Ltd.
