Why does the terrace leak after tiling? Why does the terrace leak after tiling?

Terrace, including bathroom, kitchen and other places where tiles leak, the reasons and solutions are the same, you can refer to my previous answer:

The bathroom is the most stable place in the building structure, and the probability of water leakage is the lowest.

Toilets use a lot of water and use more water points, which is a habit of people. The ground, especially the corner and outlet, is wet all the year round. Once the water leaks, it is impossible not to treat it.

Since it must be dealt with, the first step is to determine the cause of the water leakage. There are generally only two main reasons for water leakage in the bathroom. One is that the pipeline leaks, and the other is that the waterproof layer fails to leak. These two must be one or two. To judge the cause of water leakage, the elimination method is usually used. There is always water in the pipe. If the water is suspended or not spilled on the ground, the water leakage problem is solved, usually the waterproof layer fails, and vice versa.

If there is something wrong with the water pipe, it needs to be replaced with tiles, and the waterproof layer will be destroyed. At the same time, vibration may affect the quality of the floor. Therefore, the waterproof layer should also choose the appropriate material. This kind of concealed work is suggested to be completed in one step, otherwise it will be troublesome and costly in the future.

If the simple waterproof layer fails to cause water leakage, there are two maintenance schemes:

Smash the tiles first, and then make the waterproof layer again. If you choose the right waterproof material, you can completely solve the potential water leakage problem in the future once and for all. Pay attention to the selection of suitable materials. But it will cost a lot of money, such as bathtubs, toilets, bathroom cabinets and other ancillary facilities, which are likely to be replaced. At the same time, if the wrong material is selected, the loss will be even more annoyed if it leaks again in the future.

The second is to use transparent waterproof coating, which is applied to the surface of ceramic tiles without breaking bricks. This method has low cost. The disadvantage is that the coating is thin and cannot be done once and for all. If the quality of the building is poor, brush it again in a few years. In addition, the market of this material is extremely chaotic, and there are many gimmicks without bricks, but few of them really work.

No matter which scheme it is, remember that waterproofing is never cheap. Greedy and cheap can't buy the real thing. People think waterproof is cheap, which is an illusion caused by counterfeiting. You can see how different the waterproof materials in the real national standard are from the counterfeit ones. The materials in the national standard can only reach the average protection level of 5 years according to the national regulations. This shows that the waterproof cost in western developed countries accounts for 7~ 1 1% of the total project cost.

Friends who want to solve the water leakage problem once and for all can learn about polyurea waterproof coating, which is the most advanced special protective coating in the world today. China has independently developed and mastered the core technology. Only a few major countries in the world have this technology, and developed countries like Japan and South Korea cannot independently develop it. At present, it has been listed as the promotion project of waterproof special scientific and technological achievements of the Ministry of Construction, but few people know it. All kinds of "Gui Li" also came out to dance wildly, endangering the people. Pay attention to screening. Waterproofing looks simple and the routine is deep.
