When the tide recedes, you will know who is swimming naked. After a heavy rain, the poor quality waterproofing of the real estate was revealed.
In the third phase of Taoyuan Village, Shenzhen, the owners only stayed on New Year's Day this year. They were happy to move in only 2 months and discovered that the residential houses had water leakage and other quality problems. In addition to the normal life and work, the residents of the area had to be divided into 'floods'. . This matter has caused the attention of relevant leaders of the Shenzhen Municipal Government.
Coincidentally, a sudden rain and snow days also exposed the quality problems of certain residential buildings in Daqing, Heilongjiang. The owners faced the 'wishes' that appeared in their homes and could not help but ask: Why is construction waterproof not always in place?
Water leakage into complaint hotspot
After receiving the report from the owner of the third phase of Taoyuan Village in Shenzhen, on February 18, the Deputy Secretary-General of the Shenzhen Municipal Government, Huang Jinkui, presided over the symposium. Huang Jinkui said that the relevant departments have to solve the leakage problem that has already occurred within one month, and the final result is to satisfy every household owner.
The person in charge of the Shenzhen Municipal Housing Project Management Station responsible for the construction of Taoyuan Village Phase III apologized to the owner. He said that the station has supervised the construction unit to increase maintenance efforts. After finding that it was not doing well, it hired 200 construction teams to enter the field for maintenance. With regard to leakage of toilet seepage, the station will organize experts to conduct demonstrations and communicate with the owner after repairs.
A responsible person in charge of housing quality supervision in Shenzhen said that: The construction unit will be instructed to organize the power to complain to the owner's home to check on the spot; a warranty plan shall be formulated to repair the problems reflected by the owners such as seepage water and hot and cold water pipes. First obtain the owner's approval; verify the relevant situation, and make public the results of the investigation; set a time limit for the warranty unit and complete the maintenance work as soon as possible until the complainant is satisfied.
The leakage of houses in Taoyuan Village, Shenzhen is not an example. According to Xinhua News reported on March 2, 'house leaking, house purchase deposit is not refundable, mobile phone black screen, clothing suspected of counterfeiting' has become a new complaint hot spot for consumers in Henan.
A news story in Daqing, Heilongjiang, reported the same problem: During the week from February 27 to March 5, residents of Daqing City reported more problems to the mayor's hotline, which was mainly related to the leakage of houses. According to reports, this week, the mayor of Daqing City accepted a total of 2415 incoming calls from the public.
Due to the changing weather in Daqing City this week, rain and snow are the main factors. Therefore, the rain leaked from the ceiling has not been dealt with for many years. Water leakage has continued after waterproofing has been done. Rainfall on the ceiling has become the focus of public concern this week. problem.
According to a public report, the room 4-26A-2-601 in Xincun has been leaking from the ceiling of the room for three years and has not yet been resolved.
Some of the top floors have been treated with water, but some citizens still report that they have just finished the waterproofing and the house leaks. Ms. Yang of the public encountered such distress. She lived on the roof of Ms. Yang’s house at Unit 3602 of Building 9-81 of Dongfeng New Village and had just finished a waterproof treatment. It rained the next few days and the house was still leaking.
A similar situation is Room 601, Unit 1, Building 2-49, Jian'an Group, Longfeng District. The indoor ceiling is leaking and the property has not been maintained. In addition, the public also reflected leakage in the ceiling of Room 2-601 in Building No. 1 of Yimin Community.
Well-known real estate also leaks
Vanke's development in Shanghai, Golden Arthur, was recently exposed by the “Daily Economic Newsâ€. Related reports said that it uses new technologies with shorter construction cycles, resulting in a variety of quality issues such as 'soundproof doors' and 'water leakage doors'. According to reports, there have been noise problems in the buildings of Vanke Golden Building which have been submitted to the housing. Upstairs, downstairs, neighbors can hear each other in the other room's voice. Bathroom seepage phenomenon also appeared. What's more, some of the bathroom leaks can leak into the bedroom and the study near the bathroom. However, Vanke Shanghai is rectifying the quality problems of Golden Art. By adding 'insulating cotton' to the walls and adding waterproof layers, the quality of the houses has been completely solved.
Recently, this reporter has also received a complaint about a well-known real estate. Ms. Xu, who lives in a well-known community in Beijing’s Asian Games Village, has a cracked floor at home. There is always a watermark from the floor up to a foot wide. Find a number of expert consultations to determine if there’s a problem with the building’s waterproofing. Leakage caused. Talked with property, developers, neighbors several times, no results. Ms. Xu complained to this newspaper that she 'wanted to waterproof her neighbor'.
Poor waterproof products flood the market
In the face of leakage, households have to spend a lot of manpower and material resources for repairs every few years. The quality of waterproof materials not only affects the service life of construction projects, but also directly affects people's work and life. Although the cost of waterproof material is negligible in the construction cost of the whole building, the waterproof effect of the building is of vital importance to the quality of the building for ordinary residents.
At present, China's waterproof material has basically formed a waterproof material industrial system that has a complete range of varieties, product specifications and grades, and process equipment development has begun to take shape. There are almost all foreign varieties in China.
However, compared with foreign advanced countries, China's waterproof materials currently have the following major problems: First, the product structure is irrational; the production and use of new waterproof sealing materials are very small; second, the product quality is generally low, and counterfeit products flood the market. Third, the application technology for design and construction needs to be improved, and the leakage of the building is still quite serious.
An expert from a waterproof material manufacturer in Beijing interviewed this reporter: “Currently, poor quality products are flooded with markets and waterproofing projects. This is related to the fact that many companies are engaged in workshop-style production and have not established a modern enterprise management system. '
According to reports, lack of technical personnel in waterproof material companies has become the main reason for hindering the development of enterprises. Most of the production and construction of enterprises are migrant workers. They learn to work hard and do not change the situation. Invisibly, they bury hidden quality problems in the project. Some business management is not in place and the production process is not strictly controlled. The production personnel do not have a thorough understanding of the entire production process and do not control the points that should be controlled in production. This results in unstable product quality. Some companies do not attach importance to the inspection work, and some laboratories are in name only, and some have insufficient laboratory inspection capabilities. The quality control of raw materials, semi-finished products and finished products is not in place. Some companies generally lack understanding of the environmental performance of products, coupled with the strict requirements of domestic raw materials on environmental protection indicators, and the high prices of imported raw materials, resulting in unsatisfactory environmental protection indicators for products. The waterproof material industry needs to adjust its structure and regulate the market.
Design and construction hidden dangers
The problem of leakage has become increasingly serious. Many water spills occurred in the year of delivery to the new building. Not only are they related to poor quality waterproof materials, but they are also largely related to design and construction.
In recent years, the pursuit of changes in urban architectural modeling has become a trend. There are more and more odd-shaped building facilities and new types of roofing decoration materials. Residential decoration is becoming more and more upscale and luxurious, which greatly increases the difficulty of waterproofing projects.
A designer of the China Institute of Architectural Design and Research told the reporter that at present, architectural engineering design is not enough attention to waterproofing, and many designers do not quite understand the application of waterproof materials, actual engineering conditions, waterproof material standards and construction specifications, resulting in design and actual The situation is out of touch. Coupled with some unscrupulous dark box operations, restricted the selection of materials, in this case, waterproof quality can not be discussed.
In the past, large-scale construction companies basically had established waterproof branch offices. The employees were stable and had strong technical force. In recent years, under the subcontract system under the general contracting system in the construction market, many professional construction waterproofing companies of the year have become 'professional renters' due to various reasons, and a large number of migrant workers without any professional training have entered under the leadership of contractors. This area. As a result, they either blindly operate because they do not understand the construction process, or because they have violated the technical specifications by their own interests, or they have perfunctory in the name of grabbing time.
Since the waterproof layer is a concealed project laid under the tiles, it is difficult to identify the overall quality and endurance period through water-removal experiments. Therefore, many unscrupulous construction workers take advantage of the loopholes to fool consumers with the unspoken rules of 'keep yok' for a year. They earn more profits by cutting corners, and after completing the money, the promised five-year warranty often becomes a nonsense.
Some contractors had finished their work and left 5% of the funds to be settled. It is nominally a guarantee fund. Once a water leak occurs, it is difficult to find them again. Because a considerable number of contractors are aware that dealing with partial leaks is often more troublesome than doing new projects, they would rather give up 5% of the final payment.
Experts remind consumers that if you want to eliminate leakage concerns, you must first use well-known brand products with advanced technology and reliable quality to avoid the damage caused by counterfeit materials. In addition, it is necessary to entrust the supervision or personal on-site supervision and require the construction party to refer to the product description for construction and to avoid arbitrarily reducing the operation and materials.
New standard 17 building materials standards implemented in March this year
Recently, the National Development and Reform Commission approved 228 industry standards, including 17 building materials industry standards.
The standard names are as follows: glass fiber reinforced plastic pultruded hollow profile for doors and windows, alum stone expansion cement, cement mortar sandstone wear resistance test method, self-stressed cement physical inspection method, stucco plaster, chromium alloy cast grinding ball for building material industry, cement Rubber sand shrinkage test method, cement grinding aid, rapid inspection method for cement strength, multi-channel pulverized coal burner for cement industry, antibacterial performance of antibacterial plastic pipe for construction, glass fiber reinforced cement (GRC) decorative products, concrete antifreeze, Precast reinforced concrete square piles, glass balls for glass fiber industry, one-component polyurethane foam sealants, and soft water-permeable pipes.
New Development Guangdong Quality Supervision Penalty Country Garden Subsidence Building Materials Door
On February 26th, Guangdong Province, the Quality Supervision Bureau of Guangdong Province announced the use of unqualified building materials on the list of projects, Country Garden Foshan Gaoming Phase II project was among them. Due to the use of unqualified single-phase three-pole plugs in the renovation process, Country Garden's project was ordered by the Bureau of Quality Supervision to make corrections.
According to the inspection report by the Bureau of Quality Supervision, the single-phase three-pole plugs used by Country Garden Foshan Gaoming Phase II project did not meet safety requirements in heat, heat and flame resistance tests. ' Under certain conditions of use, there may be excessive thermal deformation, endangering safety or even the risk of fire. 'As a result, the Bureau of Quality Supervision requested that the project be rectified immediately.
According to the public information of Country Garden, Country Garden Foshan Gaoming Phase II Project is a boutique mansion invested by Country Garden with a total investment of 1.5 billion yuan. It covers an area of ​​100 hectares and is located next to the two natural reservoirs in Lixiaping and Changkeng of Gaoming Sanzhou. It is Country Garden in Foshan. One of the flags.
'This problem should cause alarm. 'A Guangzhou industry person familiar with Country Garden said that although this does not represent a serious problem with Country Garden's product quality, at least 'Country Park has been overlooked in the process of product quality control'. According to the “Daily Economic News†report, Taishan Country Garden’s house also experienced wall cracks, seepage, and water leakage. Even Country Garden's first project outside the Guangdong Province, Changsha Country Garden Phase 1, also exposed quality problems and may have led to poor sales.
According to the staff of the Quality Supervision Bureau, it was found that the unqualified building materials quality did not mean that the construction quality was unqualified. If the construction unit took timely remedial measures, it could still recover the impact.
