Housing is an important carrier of family culture, and mortal life is accompanied by infinite joys, sorrows, and griefs at home on this eternal stage. As the most significant consumer investment in the lives of ordinary people, housing seems to have become a lingering pain in people's hearts. Relocations, dwellings, mortgages, complaints, etc. have all scratched and no time has passed.
During the period of 3.15, FM101.5 Chongqing Economic Broadcasting and Chongqing Owners Network released the “Chongqing Housing Quality Blue Book†in the transparent broadcast room of the Economic Broadcast Liberation Monument. The Blue Book shows that the failure to meet the standards for waterproofing in kitchens and bathrooms has become a common problem in commercial housing. Among the more than 1,000 commercial housings that have been inspected, nearly 90% of the waterproof housings fail to meet the standards.
"Release Name": House, anti-also. Wind and rain shelter are the hallmarks of housing construction. Such a high leakage rate is somewhat excessive. If Mr. Du Lao is there, and seeing this situation, a modern version of "The Thatched Cottage is the Song of Autumn" is bound to turn out.
In fact, this should not be a problem when building civilization and waterproof technology are so advanced. Solving this problem requires only a little more attention to the details of the waterproofing issue, as well as the conscience of the waterproof contractor.
90% failed, not a day's work. Waterproof market in Chongqing, the typical long time. The author believes that there are many causes of leakage, and improper use of timber is the main cause and the culprit. Here only some of the phenomenon of the existence of waterproof material in Chongqing market will be analyzed, readers may be able to see the glimpse of the leopard.
Repeatedly banned - flooding of unqualified waterproof materials In order to avoid suspicion of empty talk, I also quoted official data to confirm this issue: In the third quarter of 2010, the city quality supervision bureau organized the Shapingba District, Nanan District, and Yongchuan District of our city. , Beibei District, Bishan County, Hechuan District, and other places of waterproofing membrane material production enterprises conducted a spot inspection of a total of 20 batches of products 14 companies, qualified 14 batches, sampling inspection pass rate of 70.0%.
In general, once the regulatory authorities have heard the scrutiny of actions, manufacturers will pay special attention and try their best to cope with the past. The above pass rate should be the result of 'coping', and the passing rate in the real construction market is not so optimistic.
However, if you keep a careful, comprehensive sampling results of various time periods and the list of manufacturers being sampled, some unqualified manufacturers are stubborn in their vitality, more aggressive, and repeatedly defeated, and unqualified materials are also banned. Never stop. What I would like to add is that the above sampling inspections are for several common building waterproofing membranes and are mainly used for the roof and basement of new construction projects. Waterproof materials used in kitchens and bathrooms, especially in the circulation market of building materials, are not the focus of supervision. Checks are rarely or basically not checked, and the situation can be imagined.
Remove Wood - Mortar Water Repellent When Waterproof Coating If someone recommends a waterproof material to you, any building part can be applied. It is not only environmental protection, material saving, labor saving, but also cost-effective, once and for all, and the same life as the building, you will surely be puzzled. . But you don't have to believe it, because this perfect universal coating is available in Chongqing, streets and alleys, all over the place, and has been popular for many years.
If this is the case, Chongqing people should be proud, and the Chongqing Municipal Government should be recommended to apply for the Nobel Prize in Chemistry for the inventor of this material. You need to know that there are hundreds of waterproof materials in the world, and how many old waterproof material giants have studied for tens or hundreds of years. No one has yet figured out what the results are. No one dares to claim that a single drug is all-inclusive. It is a pity that there is such a universal protector in the house of the mountain people.
The common name for this material is mortar and concrete waterproofing agent. It is a type of cement admixture and implements the JC474-2008 building material industry standard. Cement admixtures are mainly used to improve the performance of cement or concrete to achieve the design requirements of the indicators or more convenient for construction operations. It is widely used as a single waterproof layer material, not only rare in the world, but also rarely seen in the national market.
In addition to building waterproofing, construction waterproofing requires the addition of one or more separate waterproof layers. After the building is completed, it will change with the environment, resulting in changes in telescopic deformation, settlement, displacement, etc., leading to large or small cracks in the structure. Therefore, the additional waterproof layer of the building code should be flexible, and the performance requirements of the waterproof material can have a certain degree of Extensibility prevents the waterproof layer from breaking due to cracking of the structure, thereby rendering the waterproof layer ineffective.
What we usually call waterproofing refers to the addition of a waterproof layer in addition to the waterproof structure. Concrete waterproofing agent can enhance the compactness of the structure to meet the requirements of self-waterproofing of the structure. However, waterproofing with water repellent mixed with mortar alone is a rigid waterproof layer. It is not suitable because it does not have the flexibility mentioned above. As time goes by, the surface of the structure of the house expands and shrinks continuously. Subtle cracks are produced, cracks in the waterproof layer will increase, and leakage will increase.
