During the rainy season, many owners are miserable-as long as the house leaks, the whole family will suffer. Experts pointed out that the treatment of leakage in rainy season is only a stopgap measure, and the real root removal should wait until sunny and dry winter, which is the so-called "winter cures summer diseases". However, the treatment should also focus on methods, and the construction team should have construction qualifications to prevent the use of counterfeit and shoddy products. If it is difficult to determine the rights and responsibilities, we can introduce judicial expertise institutions to let everyone know.
House leakage damages the life of the building.
The editorial department of Jinghua Jiayuan can receive readers' inquiries about indoor and roof leakage all the year round, but a series of figures put forward by Zhu, chairman of China Building Waterproofing Association, let reporters really understand the universality and seriousness of building leakage. Last year, China Building Waterproofing Association released the 20 13 national project report on building leakage investigation. The sample survey involved 850 communities in 28 cities across the country, surveyed 2,849 buildings and interviewed 3,674 families. Among the 2849 building roof samples surveyed, 27 16 has different degrees of water seepage, and the leakage rate is 95.33%. Among 3674 households, * * * has 1377 households with different degrees of leakage, and the leakage rate is 37.48%. Zhu mentioned that according to the data of Beijing Construction Engineering Judicial Appraisal Center, the legal dispute of 1/4 was caused by building leakage.
"However, what we want to attract public attention is that leakage is not only related to the quality of life of a family, but also damages the life of the whole building and causes property losses." Zhu said that residents living in apartments are generally concerned about their rooms. If there is water seepage, they will make some minor repairs. There are many leaky houses that don't live or rent all the year round, so we let the problem exist. Including seeing water seepage in the underground garage, few owners take the initiative to reflect to the property, "walk over when you see a puddle." As we all know, building seepage is very harmful to the building itself. Experts also pointed out that the harm of building seepage is gradual and not obvious at first, so it is easier to be ignored.
Zhu explained that water is pervasive, and concrete itself has pores. Water can corrode internal steel bars through concrete, causing rust expansion and cracking of concrete. "In this way, water will penetrate more, forming a vicious circle, and the final result is the loss of building life." Zhu cited a real case. A villa bought by a resident in Dongguan has been leaking for ten years, but it has not been fundamentally treated. Finally, after judicial appraisal, the life of the house was damaged by water leakage in these years, while the life of the building was only 50 years. Finally, the court awarded a huge loss to the developer, which shows the harm of water seepage to the house.
Judicial expertise can solve disputes.
In addition to technology, the difficulty in solving room water leakage is to find the water leakage point. On February 17, China International Roofing and Building Waterproofing Technology Exhibition held a public welfare activity of "going into the community to treat leakage", an old gentleman suggested that his neighbor's house was leaking, so he could not find the leakage point and the property could not find a solution. Now he can only watch his wall being soaked by water. On-site experts pointed out that in order to accurately judge the water leakage point, the owner can entrust the judicial appraisal department to conduct on-site appraisal. Experts pointed out that at present, there is no professional instrument to simply determine the water leakage point, and professionals in the judicial expertise department can judge the source of water leakage from the field situation according to their own professional knowledge and experience.
Recently, the reporter consulted the Judicial Appraisal Center of Construction Engineering Quality of Beijing Institute of Civil Engineering and Architecture as a consumer. The staff of the center told reporters that it is indeed possible to judge the water leakage points in residents' homes, but there is no guarantee that the facilities at home will not be damaged. "It depends on the situation at the scene. Some can be judged by observation, but some must pass the necessary tests. " The staff also said that at present, they can only accept the entrustment of the court, which means that the owners must go to the litigation stage to introduce judicial expertise. Some experts also suggested. Now well-known waterproof enterprises such as Oriental Yuhong have set up home waterproof maintenance business. You can also ask professional companies to check the source of water leakage.
You can apply for overhaul fund if the roof leaks.
In addition to indoor water leakage, the top floors and external walls of some old communities also have water seepage. According to the reporter of Jinghua Times, these problems can't be repaired through the interior decoration of the family, and need to be repaired by the property and the original construction unit. However, the root cause of many maintenance projects is lack of funds. Most owners need to discuss and approve the use of overhaul fund. "The original use of overhaul fund needs to be discussed and approved by the owners whose exclusive parts account for more than two-thirds of the total construction area and more than two-thirds of the total number of people within the scope of residential special maintenance funds." Zhu said that in reality, many owners have not been affected by water seepage, so this fund is not easy to use.
However, it is necessary to remind the owners that the auditing standards for the use of special maintenance funds for residential buildings in Beijing have changed, and the leakage caused by waterproof roof damage has been listed as an emergency that threatens the safety of housing use. Without the discussion and consent of the owners, the special maintenance funds for residential buildings can be used for maintenance, renewal and transformation of the use parts in accordance with relevant regulations.
The construction unit must be qualified.
Who should I repair the water seepage at home? Experts stressed the need to find a professional team. How do ordinary consumers distinguish between professional teams and guerrillas? Zhu said that the first thing to look at is qualification. Domestic waterproof construction companies need qualification certificates from local construction authorities. "Before 20 14, the qualification of waterproof construction units was divided into two levels and three levels. This year, the relevant departments adjusted their qualifications, and now it is 1 level, level 2. " It is reported that the qualifications of all units will be adjusted by the end of next year. "At present, there is no problem with old qualifications or new qualifications, but you must have qualifications, otherwise you are a guerrilla." After consulting several professional waterproof companies, the reporter learned that it is necessary to go to the door to find out the reason for the blockage at home, and then the construction will be carried out by professional construction personnel. "Materials and labor need to be calculated according to the actual project." If the tiles are damaged, some companies can also provide tiling services.
As a chemical product, waterproof and plugging materials are difficult to enter the consumer's shopping list, let alone choose common sense. Some experts pointed out that some unqualified products are even toxic and harmful. Zhu pointed out that our products should be bought in large building materials supermarkets. "Even if the roadside store is nominally a big brand such as Oriental Yuhong and Zhuobao, it must be questioned." For harmful substances, there are clear restrictions in national standards. Qualified products can be used with confidence, and consumers can pay attention to the environmental certification mark of products. In addition, consumers should try to buy water-based materials instead of solvent-based materials, such as polymer cement coatings and acrylic coatings, which have little impact on the human body.
case analysis
1. There is a watermark on the ceiling of my downstairs balcony, and it is suspected that my house is leaking. The situation is that there is a washing machine on my balcony, but the drain pipe is plugged into the floor drain. The main engine of the wall-hung boiler is also in this space. If the underground pipeline leaks, the pressure of the wall-hung boiler will drop immediately, but now the machine is running normally. Unable to find the leak, the neighbor looked for the door several times. I also want to cooperate, but I don't know why, I can't let my neighbors dig holes to find leaks.
Expert analysis: Wu Ming, an expert from China Building Waterproofing Association, said that there may be two situations: First, the windows of the downstairs residents are aging and seeping into the rain, resulting in watermarks on the ceiling; Second, there is a gap between the floor drain and the cement joint connecting the washing machine pipeline. Usually, water overflows from the drain pipe and leaks downstairs along the gap in the ground. It is suggested that the owner adopt the exclusion method. First, he can buy plugging products to block the floor drain and see if the watermark downstairs has deepened. Because it takes a long time for the wall to dry out, we also ask the owners downstairs to cooperate with us to "observe for one or two months".
2. A household upstairs leaks water, which causes the ceiling of my bathroom to leak, but this situation sometimes doesn't happen. The people upstairs said that the house has been empty, there is no water at all, and there can be no leakage. I don't think it is possible for water to leak into my house just after passing through several houses. The property is now at a loss. What should I do?
Expert analysis: Wu Ming analyzed that the upstairs residents did not use water, and the source of water leakage is likely to be in the farther households. Why didn't the leakage of a resident upstairs directly show up in the nearest neighbor's house? This is because their floors or cushions are relatively dense, and water will flow into the owner's house along the loose concrete near the wall. As for why sometimes there is no, it is because flowing water will accumulate on the mat or floor, slowly leak and regain moisture. If there is no new water supply for a period of time, it means that the water leakage situation has improved. In view of the complexity of the situation, it is suggested that the owner ask the judicial expertise center for professional expertise to determine the missing points.
