Summary of the cause of water leakage in the bathroom

Summary of Causes of Water Leakage in the Bathroom Waterproofing works is essential for your home to be waterproof and without bathroom decoration. However, there are also such cases. During the renovation, there was no problem with the waterproof test. After the check-in, there was still water leakage? What is the reason? The water and electricity master reminded that it may be waterproof or not in place. Water leakage occurs after the closed water test has been done. The common reasons are summarized: Phenomenon 1: After the decoration has been completed for 1-2 years, no water has leaked during the period, but water seepage will occur in the bathroom. Reasons: 1. The building has a large expansion and settlement degree, which exceeds the waterproof stretch and the waterproof layer is torn. 2. The waterproof coating itself is not strong in water resistance and corrosion resistance. 3. Displacement of sewer pipes. Phenomenon 2: The closed water test is no problem, and the water seeps downstairs a few days after moving in. Reasons: 1. In the process of bricklayer construction, due to the leveling of the ground or the large curvature at the corners, bricks cannot be laid, so the waterproof layer is removed. Phenomenon 3: After moving in, the wall of the bathroom returned to moisture, or the wall opposite the door became moldy. Reasons: 1. The waterproof coating is applied unevenly, and there is trachoma on the wall. 2. There is no pre-treatment for the waterproofing of the bathroom door, and no water-retaining edge, which causes the water vapor to seep into the wall along the emptiness of the floor. Phenomenon 4: The toilet door cover seeps and swells. Reason: During the construction process, the door cover was not treated with a set of pressed stones, and water vapor seeped into the door cover, which caused the door cover to swell. In summary, the above phenomena are actually caused by insufficient rigor in waterproofing works. Now we are systematically understanding the specific details of the waterproofing project. 1. Grassroots treatment: Before waterproofing, level the ground first. The ground is evenly leveled, and the waterproof coating can be applied more evenly. The subsequent cracking and leakage phenomenon is less likely to occur. The joints of floor drains, wall corners, pipe heels, etc. should be dealt with in particular. 2. The first time of waterproofing: The thickness of the painting should be handled carefully according to the requirements of the waterproof product. The bathroom height is 180cm. If the design is dry and wet separation, the wall height of the dry zone is 120cm, in order from the inside out, first up and down. Paint. 3. The second time of waterproofing: the second time of painting must be done after the first time of waterproofing is completely dry to form a film, and the direction should be opposite to the first time of painting. 4. Closed water test: the room should be filled with water, the water storage depth is 30-40mm, and the time is 24-48 hours. After the test, go to the neighbor's house downstairs to check for water leaks. 5. Re-protection of waterproof coating: After completing these procedures, in order to avoid damage to the waterproof coating, a protective layer should be laid on the surface of the waterproof coating. Completely cover the waterproof layer, and firmly bond with the base layer, check whether there are cracks, bubbles, falling off and other phenomena. (
