Anonymous users2024-01-24There may be two reasons for this, since you have tried water, it means a problem, and it is okay to be waterproof at first.
The first one may be that your water pipe is made under the waterproof, and the water pipe is leaking. This has nothing to do with waterproofing, because waterproof is on top, and no matter how good the waterproof is leaking below you, it will not be used. It is also easy to rule out whether this is the cause, and you can check whether the water pipe is leaking by pressing the water pipe.
The second is that the waterproof layer is damaged in the later construction, such as the construction slag is used when backfilling, and the construction slag is not paid attention to when it is poured, which is likely to damage the waterproof. It is also possible that the quality of the waterproof material is too poor, resulting in natural cracking in the later stage, which is very unlikely. If it's not a leaking pipe, it's a waterproof problem.
After the bathroom is waterproofed, it needs to be thoroughly dried, so that it can do the closed water test, you can contact the residents downstairs in advance, so that the leakage can be informed in time to avoid unnecessary losses of the downstairs residents When doing the closed water test, the depth of water storage can not be less than 20 cm, and the time can not be less than 72 hours, and the water level does not fall is qualified.
Let's go downstairs and tell me first. I'm going to test the waters, you pay attention. Then you test the waters for 24 hours. Take a flashlight downstairs to the shed to see if there is a water leak.
This even if it is a master does not dare to pack a ticket, how good is the waterproofing, with daily use, external factors, etc., especially with the aging of materials over time, there will be leakage gradually, and testing the water for ten days is just a test.
Generally, the waterproofing of the bathroom is made of flexible waterproof mortar, so it usually dries within 24 hours, and then you can do a closed water test, that is, test the water. This time is not absolute, some quick-drying waterproof coatings have been dried in 4-6 hours, so after 10 hours, you can do a closed water test. >>>More
It actually depends on what kind of waterproof coating you use, but the general waterproof coating such as JS, waterproof mortar, and polyurethane waterproof coating has a dry time of 24 hours, and you can do a closed water test after drying.
