Maintenance method: Look at the size of the water leakage point. If the scope of leakage is large and one or another line is leaked, then the bathroom can only be completely demolished and renovated. However, if the water leakage point is very small and there is only a little water leakage, it can be treated with osmotic waterproofing agent. Waterproofing agent has strong water permeability, which can reach the water leakage point through the floor tile and cover the water leakage point to dry. After drying, a hydrophilic membrane is produced to achieve the effect of river closure.
Reason 2: The waterproof layer leaks. In fact, there are some imperfections in the closed water test, such as the "water leakage point after the closed water test" mentioned above, which cannot be detected. There is also an imperfection: the closed water test only checks the pavement waterproof layer, not the wall waterproof layer. And only check the waterproof inside the bathroom. The bathroom door may need to be waterproof, but it can't be checked. If water seeps from the bathroom wall or overflows from the passage, it will also cause water leakage. It will also cause many problems such as Aspergillus flavus on the wall, bagging, deashing and falling.
Maintenance method: according to the analysis of damaged wall parts, judge the leaking parts. If the damaged wall is in the bathroom passage, water is likely to overflow from the bathroom passage. In this case, there are two ways. 1. All the floor tiles (wooden floors) entering the entrance are removed, and the waterproof layer is painted at the entrance of the bathroom 1 area). 2. Only one or two floor tiles (wood floors) are removed at the door, and doorstones are installed at the door of the bathroom. Stone is waterproof, so can the door in the shower. If other walls are leaking, it is likely that the walls are not very waterproof. At this time, it is suggested to use high-pressure grouting to make up for the water leakage. Make a hole in the wall next to the bathroom and use high-pressure grouting as waterproof slurry to make up for the leakage point of the waterproof layer.
Reason 3: The damage of water pipes leads to rapid water leakage and rapid expansion of water leakage range. And even if there is no water at home, the water is still leaking. There are many reasons for the damage of water pipes, which may be assembly problems (lack of joints) or late damage). During the renovation, the tap water pipe was trampled. There are various types of water pipes. It may be a cold water pipe or a heating pipe; It may be a drain pipe or a heating pipe. Maintenance plans vary from pipeline to pipeline.
Maintenance method: cold water pipe/heating pipe/heating pipe must find the water leakage point. Now there are also infrared detectors, which can see the water flowing on the surface of the tap water pipe passing through the floor tiles and concrete. At the location of the water leakage point, you can see too much water overflowing. Even without professional equipment, you can use in-ear auscultation or rent it. After finding the leaking point, take out the floor tile near the leaking point, disconnect the leaking pipe and replace it with a new one. The most important thing is to find the leaking point, properly remove the floor tiles and minimize the loss.
