In the summer, there was an increase in rainwater, and many families successively reported housing leakage. People have always thought that only old houses will be leaking when they are in disrepair. Nowadays, many new building owners have found that there are water seepage and water leakage in the bathrooms.
It is understood that because the waterproof layer is a concealed project laid under the tiles, it is difficult to identify the overall quality and endurance period even through water-removal experiments. As a result, some real estate developers and their downstream companies have earned profits from them by cutting corners and other means, but in the end it has always been the owners. Therefore, the industry can only increase vigilance on this invisible or intangible link, so as to truly save money for the use and maintenance of the house in the future.
Buildings are also like people's bodies. They need to face the wind and rain and experience the natural process of 'death, death, sickness, and death'. If you are old, you should pay attention to health care. However, the problem of seepage and leakage due to human factors tends to be 'rejuvenated'.
Case 1
It’s a mischief
Ms. Mei purchased a house about ten years old and hired a contractor through a friend's introduction. After a month of renovation, the house is doing well. The contractor finished work and left 5% of the pending funds to Ms. Mei, which is nominally the warranty fund. After all, the renovation of second-hand houses is difficult N times than the renovation of new houses. However, in less than three months, the toilet leaked. According to professional analysis, it may be due to the reduction of the waterproofing process caused by the decoration.
Comments: The decoration team is mingling with many workers who have not received any professional training. Others are deliberately violating technical specifications for their own interests. The general manager of urban love family Yu Zhong-ling suggested that the industry should mainly entrust trustworthy people to supervise or personally supervise on the spot to prevent workers from arbitrarily reducing their processes. It is understood that there are only N steps in waterproofing. The industry mainly pays attention to whether the construction team has completed the following processes: pouring fine-grained concrete side beams with a height of no less than 120mm around the bathroom, and carefully inserting and inserting the compaction or not, and then laying hollow bricks or lightweight walls to prevent water Leakage from the corner of the wall; pipes should be embedded in the steel casing when passing through the floor; small-bulk concrete should be poured into the gap between the steel casing and the pipe; and the steel casing should be buried in the middle of the floor section. Add a BW sealing strip, and after removing the floor grout and oil impurities, apply primer and waterproof coating.
Case 2
Lose money
Ms Li, a white-collar worker in the city, has been in the new house for six months. The ceiling has recently become a 'water melon shed'.
Why does a new house leak? Generally speaking, the wet space in the bathroom and so on will increase the waterproof layer. Generally, the polymer made of the liquid material plus the powder material is used as the cement-based waterproof coating. After inspection, the engineering team may replace it with glue and other materials in order to save money.
Comments: The quality of waterproof materials not only affects the service life of the building space, but also directly affects people's work and life. Although the cost of waterproof material accounts for a small part of the construction cost of the whole building, the waterproof effect of the building is crucial to the quality of the building. However, because real estate developers put the cost of fine decoration projects at a low level, after the construction party obtains the construction order at a very low price, he must “do his work†in order to earn the remaining profits. There is a joke in the industry that waterproof projects can be 'qualified' more than a year ago.
Picking the waterproof coating is the key first step. There are various types of waterproof coatings on the market, and many professional nouns such as 'polymer', 'one component', 'water', and 'acrylate' have caused many consumers to feel dizzy. At present, there are various types of waterproof paints on the market, such as 'slurry' and 'gum paste', and there are also water-repellent coatings classified into type I and type II. Some people say that Type II is more suitable for indoor use. It is important to remind everyone that it is only necessary to know what kind of waterproof coating is used when purchasing. The price is also an important reflection of product quality. If two buckets of the same capacity of paint, if the price difference is too big, consumers have to question the product performance.
The construction team buys building material products usually have rebates, so consumers are best to go shopping for some building materials supermarkets themselves, to buy reputable building materials supermarkets waterproof coatings, because some building materials market mixed, it is difficult to ensure that consumers buy It is real goods.
