The prevalence of building leakage and the difficulties it has brought to people's lives have attracted the attention of CCTV. On July 9th and 10th, the financial channel (CCTV-2) was titled "Leaky Waterproof Materials" in the "Economic Information Broadcasting" program for two consecutive nights after the prime time, which caused the root cause of high construction leakage in China. The issue was thoroughly investigated and reported. The following is a record of the contents of the survey broadcast on July 9.
　　Leakage issues account for 40% of the number of construction judicial appraisal cases. It
　　is often said that "building is a hundred-year plan". In addition to being strong, the construction project needs to be waterproof and moisture-proof. However, the quality of waterproof materials is often ignored by people, so inferior waterproof materials are used. The resulting housing leaks occur from time to time, and the scope of the leaks is so wide and the hazards are unimaginable. The reporter recently selected Qinhuangdao City, which has the highest housing penetration rate in North China, to investigate and look at the reporter's report.
　　Jiao Zhensheng is an owner of Bohai Pearl District in Qinhuangdao City, Hebei Province. In 2009, the second year after he stayed in the community, he embarked on a difficult road of rights protection due to housing leakage and more than 2,000 residents of the community. .
　　Jiao Zhensheng, the owner of the Bohai Pearl District in Qinhuangdao City, Hebei Province, told reporters that there were only leaks in the homes of more than 100 residents at the time in 2009. After a heavy rain last year, more than 900 homes in our community were leaking, and some of them were wiped. It's so deep across the knee.
　　Jiao Zhensheng took out a thick file bag full of photos taken after a leak occurred in the residential area of ​​the community. He told reporters that due to the long-term leakage, nearly half of the residents in the entire community have varying degrees of peeling, hair growth and cracking on the walls, roofs and floors of the residents. For this reason, more than 500 residents of the community recently sued the community developers collectively.
　　Owner of Bohai Mingzhu Community, Qinhuangdao City, Hebei Province: The house leaked every day can't live, it's really poor waterproofing.
　　Owner of Bohai Pearl District, Qinhuangdao City, Hebei Province: Look at the mottled black spots on the outer wall of the building. These are the developers who have recently repaired the outer wall of the community.
　　Reporter: Was the external wall leaking badly before?
　　Owner: Very powerful. When it rains, there is rain in the windows.
　　The owner of the community also told reporters that the basement and underground garage of the community have been accumulating water for a long time, and it is impossible to enter it when it rains. Although it has been a week since the last rain, the reporter found that there is really deep water in the basement.
　　The reporter appeared (Zhang Wenjie): When I came to the basement of one of the buildings in the community, I found that there is still thick water. There are at least more than 20 rooms with deep water like behind me. Everyone sees that my shoes are soaked. By the way, the underground water can see how deep it is from this angle.
　　In the underground garage, there are at least ten leaking corners, and in severe places, parking is even impossible. Afterwards, the reporter visited five other communities in Qinhuangdao and found that there were also housing leaks.
　　Owner of a community in Qinhuangdao, Hebei Province: Some of us here are very leaky.
　　Owner of a community in Qinhuangdao, Hebei Province: The walls and floors of the house are damp, many and some have cracks.
　　According to statistics from the China Building Waterproof Association, the leakage rate of Qinhuangdao houses exceeded 80%, the highest in North China. At present, the average leakage rate of houses in the country is 65%, and the leakage rate of underground buildings exceeds 80%.
　　Ye Linbiao, deputy director of the Waterproof Technology Expert Committee of the China Architectural Society: In the field of construction, the most complaint is housing leakage, which accounts for 25% of the total complaints. There are many reasons for this. Raw materials are the foundation, and construction is the key.
　　Ye Linbiao told reporters that currently in China, building leakage has become the second largest problem affecting building quality in addition to building structure, and is called "building cancer".
　　Ye Linbiao, deputy director of the Waterproof Technology Expert Committee of the China Architectural Society, told reporters that the leakage will cause the steel bar to swell. After oxidation, the steel bar will swell more and more, which will squeeze the main structure and cause safety problems. The vicious cycle will continue to decrease Building life.
　　The sales of unqualified waterproof membranes in the building materials market became public secret
　　reporters learned through interviews that the direct cause of "building cancer" is inferior waterproof materials. So how did these inferior materials enter the construction site, and how did the sales of the building materials market? The reporter selected the Shanghai market, which has the strictest domestic supervision, to investigate.
　　This is Nanda Road, Baoshan District, Shanghai. There are more than 10 large and small waterproof material distributors on this street. One of the sales staff told reporters that they are a distributor of a certain brand, but when the reporter expressed The sales brand was not satisfied. When asked if they could get some other well-known brands, the sales staff agreed.
　　Reporter: Can Donghong Yuhong get it?
　　Shanghai Nanda Road Waterproof Material Distributor: Yes.
　　Reporter: Is it new?
　　Shanghai Nanda Road Waterproof Material Distributor: Yes.
　　However, it is understood that brand manufacturers like Dongfang Yuhong adopt the model of direct sales by enterprises. Generally, they are not sold through these small dealers. Will these small shops sell regular products? The dealer's special advice made the reporter feel that there was a big problem.
　　Shanghai Nanda Road Waterproof Material Distributor: We can get it for you, but you can't be the site that Dongfang Yuhong's salesperson has been to. If it's the site he's been to, you can't get it for you.
　　Later, the seller simply told reporters that the so-called brand waterproof materials they sell are actually fake and inferior substandard products, which are far from the national mandatory standards for waterproof materials, and this has almost become public. Secret.
　　Shanghai Nanda Road Waterproof Material Distributor: These are unqualified.
　　Reporter: How much?
　　Shanghai Nanda Road Waterproof Material Distributor: More than 70 pieces, otherwise it is so cheap?
　　Shanghai Nanda Road Waterproof Material Distributor: These are all non-standard, there is the national standard.
　　During the investigation of the reporter, it happened that a customer came to buy waterproof materials. The reporter stepped forward and learned that it was a property worker in a community who bought these substandard waterproof materials to repair the leakage of the house.
　　Reporter: Where are you from?
　　A staff member of a residential property in Shanghai: a residential property.
　　Reporter: What is this used for?
　　Property staff in a community in Shanghai: Leakage repaired by the community.
　　Reporter: How is the effect?　　
　　The property staff of a community in Shanghai bought customers: very good.
　　The unlicensed production of waterproof membranes by enterprises is eight times more profitable than regular enterprises
　　. The sales chaos in the building materials market is really surprising. It seems that selling unqualified products has become an open secret. So where did these unqualified low-quality waterproof membranes come from, and why they have not been effectively supervised, let us continue to look at the reporter's investigation.
　　During the investigation, some distributors told reporters that the unqualified waterproof membranes sold in Jiangsu, Zhejiang and Shanghai were mainly from Qidu Town, Wujiang City, Jiangsu Province, and Shuanglin Town, Huzhou City, Zhejiang Province. So, the reporter found a waterproof membrane manufacturer in Qidu Town, Wujiang City. When the reporter arrived, the door of the enterprise was locked and there was no factory nameplate on the door, but the outside of the door was filled with rounds for processing asphalt. Barrel, and vaguely can see that this barrel is just used. The reporter pretended to be a customer, hoping to enter the factory, but nobody opened the door.
　　Reporter: Anyone, I'll buy coils.
　　Employees of the waterproof membrane processing plant said the boss was not there.
　　Industry insiders said that these production dens are generally produced at night and closed during the day, because they do not have production licenses, so they are afraid of the management department checking.
　　Afterwards, the reporter went to Shuanglin Town, Nanxun District, Huzhou City, Zhejiang Province. On this road leading to Huzhou City, the reporter found three waterproof coil manufacturers. Apart from the closed door of an unnamed company, the other two were open. At the door of an enterprise, the reporter saw that the label clearly read the words Li's Wood, but when he entered the factory, he found that there was not even one piece of wood in the factory, and more than 200 bags were stacked on both sides of the factory. For waste asphalt, the trademark affixed to the waterproof coiled material piled in the plant is displayed as Li's brand.
　　Reporter: How much is this coil?
　　Employees of Waterproof Coil Processing Factory: More than 90 rolls.
　　On the other side of the plant is the processing equipment. Several furnaces are heating. The staff told reporters that the waste asphalt is heated in the furnace. After high temperature heating, the film is turned out to become a waterproof membrane. The reporter saw that the sewage in the entire production workshop was flowing horizontally, garbage was scattered everywhere, and thick dust covered the entire plant. In another processing plant that also had no factory name, the reporter saw that although it was not in production, there was a special person responsible for reception. When the customer came to the door, the staff took the initiative to give the reporter's phone number to the reporter.
　　Reporter: How much is your coil?
　　The owner of the waterproof membrane processing plant: more than eight square meters.
　　Reporter: Can the product pass the inspection?
　　The owner of the waterproof membrane processing factory: We are an enterprise without a license. How can the product be qualified?
　　Reporter: Can you produce a better brand?
　　The owner of the waterproof membrane processing factory: Yes, it is the production of counterfeit chants.
　　According to the person in charge of the enterprise, the unlicensed production enterprises like them generally use waste asphalt, and the price is only more than 400 yuan per ton, while the regular asphalt costs more than 5,000 yuan, which is more than ten times different. . Therefore, although the selling price of their products is only 8 to 9 yuan per square meter, which is much lower than the price of more than 20 yuan for regular products, corporate profits are about eight times higher than that of regular manufacturers.
　　Ye Linbiao, deputy director of the Waterproof Technology Expert Committee of the China Architectural Society, told reporters that this inferior waterproof membrane has much worse performance in terms of its hardness, thickness and high temperature resistance. For example, such high temperature weather, inferior membrane It will be long gone.
