Many owners of Jinmao Province, the western suburbs of Lane 885, Fengzhou Road, Jiading District, asked for help from "Xinmin Help" through the Toutiao Shanghai channel "Toutiao Help" #Toutiao Help #Entrance, and it was only two and a half years after the delivery of the new house, and the home leaked "miserable". "When I first got the house, there were traces of water leaking from the ceiling. Unexpectedly, it is getting worse and worse now, the soup drips every day in the house, the walls are moldy, and some people have changed the floor several times! ”
What makes the owners even more depressed is that the developer's "small repairs" of "headaches and pains" can not solve the problem at all, "missing repairs, repairs or leaks..." In the past few days, Shencheng has been raining continuously, and many owners' homes have become "soup rooms", so they are worried all day.

Repeated repairs and repeated omissions
According to the owners, there are 1,409 households living in the community. In August 2021, statistics for half a year of handover showed that 105 penthouse houses leaked. In the year since, the problem has worsened, with 65% of penthouse leaking water. Although the developer took measures to fill the leak, 110 households still leaked water until December 2022.
The owners told the Xinmin Evening News "Xinmin Bangnong" reporter that the living room, corridor and bedroom were the "hardest hit areas" for water leakage in the penthouse on the top floor. Since handing over the house, the owner, Mr. Yang, has found traces of water leakage from the ceiling, and last year even began to drip water, and now the walls of the living room, corridor and two bedrooms have printed water, cracks, bulges and mold. "It leaked all the way from the ceiling to the skirting board, and the floor was changed 3 times due to severe deformation!"
From the photos sent by the owners, it can be seen that after the delivery of the new house, water leakage continues, wall cracks, bulges, peeling, mold spots, etc. abound, and even large basins and small basins are used to receive water in the rainy season. When it comes to this, the owner, Ms. Ye, is full of resentment: "Many houses have been repaired for two years in a row, but they still keep 'running and dripping', the wallpaper is re-pasted once moldy, and Alla is about to collapse!" Ms. Ye said that the developer has only adopted the "grouting and filling leakage" method of "only treating the symptoms", while the "topping" plan of "treating both the symptoms and the root cause" previously formulated by experts is "hanging high".

The moldy house suffered
The ceiling was chiseled
The reporter of Xinmin Evening News's "Xinmin Gangnong" visited a number of "leaky houses" on the spot. On the ceiling of the living room and corridor of the owner's house, Ms. Shi, dark black mold spots, light yellow water stains are clearly visible, the wall skin is wrinkled and bulging, "big bags" and "small packets" are continuous, and the wall tentacles that tear off the wallpaper are wet. "When it rained outside, the overhead lights were coming out with water. At night my room was dark and rumbling, and my mother said I couldn't turn on the lights. Listening to the words of the four-year-old child "Qiu Qiu", the grandmother's face was full of helplessness, "The developer injected glue from the outside to repair the leakage, broke the embedded wires, and the child's bedroom still dare not connect to the electricity." There are two children in the Ara house, the eldest is 4 years old and the youngest is only 9 months old. For two whole years, the room was full of musty smells, and the developer only gave a dehumidifier, and if it goes on like this, the old and small ones will have to hold out big problems. ”
Dark black mold spots and light yellow water stains are clearly visible
The north and south corners of the living room of Mr. Zhou, the owner, still have basins that receive water, and the ceiling has been chiseled to reveal blue grid-like grille building materials, and bean water droplets mixed with milky white impurities are constantly dripping. The elderly at home complained while coaxing the child who had just woken up: "It has been chiseled for a while, and the construction team said that the blue 'capillary pipe' was leaking. Originally, this was a "high technology" used to adjust the room temperature by 'cold water in summer and hot water in winter', but now it is said that it will cause condensate to leak and drip. However, the place where the 'capillary pipe' is not laid is also leaking! ”

Waterproof construction design
There is a fatal error
Recalling the delivery of the home inspection at the end of 2020, Mr. Yang regretted it. "It was not the rainy season at the time of the inspection, and the water leakage problem was not very visible. At that time, there were only some traces of water on the ceiling, and the house was closed after writing 'printed water' on the home inspection form. "But I never expected that a heavy rain hit in mid-May 2021, and Mr. Yang's house leaked a large area, and it has been out of control ever since. The owner, Ms. Jiang, "complained": "After the water leaked in the south-facing small room in 2021, the construction team shoveled off the paint layer and found that the house had leaked seriously before delivery, and there was still a row of grouting nail holes. ”
According to the owner's statistics, the heavy rainfall in mid-May 2021 caused leakage of 24 of the 30 buildings to varying degrees. In the video of roof maintenance that year, workers chiseled the waterproof layer to clear a large amount of stagnant water, then added waterproofing membrane, removed the indoor ceiling "capillary pipe", and grouted it for repair. However, the good times did not last long, and after a heavy rain in late June 2022, the houses that had been repaired leaked water again, with a leakage rate of 91%.
It is understood that after the problem occurred, the developer also invited waterproof experts to the site for investigation many times. In the June 2021 written report provided by the owner, experts pointed out that the failure of the waterproof layer was the main cause of leakage, and heavy rain was the trigger; The design defects of the roof gutter caused the insulation layer to enter the water and the main waterproof layer to lose its continuous effectiveness; There are serious errors in the design of the waterproof construction.
In September 2022, the expert group further proposed the "special maintenance plan for roof waterproofing" in the "Demonstration Report of the Special Plan for Sub-projects with Greater Danger in Shanghai Construction Projects": consider redoing the roof renovation and list the detailed practices of roof waterproofing.
At the end of October 2022, after repairing No. 61-63, the developer introduced the "Oriental Yuhong Grouting Leakage" scheme in early December, and at the same time made it clear that it would no longer "top-up" for maintenance.
Repair leakage repair plan
Repeatedly questioned by owners
Why is "grouting to fill leaks" questioned collectively? The owners believe that this practice constantly destroys the waterproof layer in actual operation, causing new cracks, resulting in more and more leakage. At the same time, the weight gain of the grouting material after absorbing water is very likely to lead to the roof pressure overload and affect the safety of living.
Xinmin Evening News "Xinmin Bangnong" reporter community property company got in touch and was told that "no interview will be accepted". Xinmin Evening News "Xinmin Gangnong" reporter called the developer's service hotline again, the project leader Mr. Sun replied that the community is contracted by China Construction Third Bureau, and the developer has mobilized housing repair forces to station in the community, and has solved the water seepage problem of more than 60 households through the maintenance plan of "Oriental Yuhong Reconstructed Waterproof Layer", and the remaining 70 households are being docked one by one.
As for "why not adopt the 'top-up' maintenance plan recommended by the expert group", the developer explained: In order to avoid the impact of powder layer and noise on other owners, the comprehensive assessment of "Oriental Yuhong" is more in line with the reality of the community than "topping", and the owners who promise to sign the contract can get a ten-year maintenance period, and if there is further leakage, a punitive cash reward will be given, with a reward of 10,000 yuan for one place and 60,000 yuan for three or more places.
However, the developer's statement once again caused dissatisfaction among the owners: the contractor, China Construction Third Bureau, once claimed that the house was built using patented waterproof technology and equipped with an integral shear wall structural system, which could eliminate the problem of water leakage, but it was directly "slapped in the face" by reality. After the launch of the "Oriental Yuhong" maintenance plan, many houses have new leakage points, and the developer has prevaricated with the so-called "roof capillary phenomenon", and the promised "punitive cash reward" is even more "empty talk".
After the Xinmin Evening News "Xinmin Gangnong" reporter intervened in the investigation, some owners who sought solutions through various channels have been notified by the developer: "topping" and "grouting up" maintenance plans can choose one of the two. But most of the other owners still did not receive a clear answer.
In this regard, "Xinmin Gangnong" will continue to pay attention.
