Why does the bathroom door crack and leak?

After the whole solidifies and dries, it is cleaned again, and it can be waterproofed at the same time. Usually the bathroom is waterproof three times, the first waterproof is dry, in order to do the last one, waterproof is not easy to do, the joints around the corner, evenly smooth the waterproof coating. There will be no problem when doing a closed water test.

However, in the later stage, there is no protective waterproof layer in the brick-laying process, and the uneven brushing of the waterproof coating is destroyed, especially the joints of water pipes and wall corners, which is easy to lead to water leakage.

<> quality control of the construction process can not be ignored, whether the parts that need to be strengthened are attached, and whether the thickness of the material is brushed enough. After doing it, whether there is a closed water experiment or not must be controlled. The decoration master is required to do cement mulch for the upper and lower water pipes of the kitchen and bathroom, brush 10 to 20 cm of polyurethane waterproof paint from the ground, and then redo the polyurethane waterproof on the ground to enhance the waterproofness.

Because the waterproof layer will not move the ground after brushing, the water test will not be a problem, followed by the floor tiles, because the tiling master wants to knock the tiles, it is possible to knock off the broken roots, so that the waterproof layer will be damaged and cause water seepage.

Polyurethane is actually a layer of airtight film, once it is punctured by the sharp object, then the above work is equivalent to doing it in vain, so the protection of finished and semi-finished products is very important. Be sure to pay attention to the decoration you are going to decorate. Do not do a good job in the waterproof layer drilling, drilling, nailing and other damage to the base surface of the waterproof layer, sixth, waterproof coating must use a good quality brand is also more important.

If the above construction standards are achieved, it is generally not easy to seepage. The prefabricated ground beam is not an iron plate, or there are pinholes, or there are iron wires left during mold making in the ground beam; Then there are the bricks used in construction, or perforated bricks, or block bricks. The judgment method is that the walls on both sides of the door sleeve are damp and mildew, and there are obvious signs of water stains, so at this time, you only need to dig out a row of tiles on the inside of the threshold stone, and then re-do the waterproofing.

Don't believe in the various crystalline and coating waterproof materials on the market, let you try to comfort yourself at that time, whether the waterproof manufacturer knows better than anyone else.

Because bathroom doors are generally made of wood, doors made of this material are easily damaged by water vapor erosion.

There is no direct relationship between the water leakage in the upstairs of your house and the door of the bathroom in your home.

Judging from your description, the wall of the door opening is a light wall, which can be removed, that is, the renovation meets the requirements of the code, and there is no leakage after the renovation is completed, but the leakage occurs a month later, which should still be caused by the damage to the waterproof itself on the upper floor.

Problem: As soon as the renovation of the new home was completed, the bathroom was made like a big tearful face by the sewage leaking from the roof of the shed. How can I avoid this from happening?

Expert answer: To solve this problem, we should mainly do a good job of waterproofing to prevent the occurrence of leakage events. Try not to damage the original waterproof layer If the original waterproof layer is not damaged, there will generally be no leakage after moving in.

However, the waterproof layer is easy to be damaged when renovating the ground, and if it is accidentally damaged, it should be repaired in time to avoid leaving hidden dangers. If you need to replace the original floor tiles in the bathroom, after chiseling off the original floor tiles, you must first level the ground with cement mortar and then do waterproof treatment. Repeat 2 to 3 times with polyurethane waterproof paint.

Be sure to do wall waterproofing Water splashes on adjacent walls when bathing in the bathroom, so be sure to do a good job of wall waterproofing before laying wall tiles.

Generally, the wall should be waterproofed with a height of 30 cm in waterproofing treatment, but for non-load-bearing light walls, the entire wall should be waterproofed, at least meter high. At the same time, pay attention to the waterproofing of the wall adjacent to the shower position should also be meters high. The groove of the water pipe in the wall should also be waterproof During the construction process, when the pipe, floor drain, etc. pass through the floor slab, the waterproof layer around the hole must be carefully constructed.

The buried water pipe in the wall should be reasonably arranged, and the water pipe should be made with a groove larger than the pipe diameter, and the plastering in the groove should be smooth, and then the groove should be brushed with polyurethane waterproof coating. 24-hour "closed water test" acceptance waterproof After the waterproofing project is completed, seal the door and drain, fill the bathroom ground with water to reach a certain liquid level height, and make a mark, if the liquid level does not drop significantly within 24 hours, especially the roof of the downstairs house does not leak, the waterproof is qualified.

The bathroom leakage of the new house has been renovated, and it doesn't matter if the door is changed, mainly because the waterproofing is not done well, if the waterproofing is done, then it will not leak.

The demolition and alteration of the decoration wall of the new house has nothing to do with the leakage of the bathroom. And you are on the second floor, and the roof of your bathroom is leaking, because the third floor is leaking, and the waterproof treatment has not been done in the process of decoration, which has nothing to do with you.

Do you still know the direction of your water pipes? It is important to consider whether there is a leak in the water pipes. In this regard, you have to find a plumber to help you do a pressure test, if the water pipe is leaking, then even if you don't use water in the bathroom, there will still be water on the ground.

If the waterproof slope is not done with cement mortar in advance before the waterproofing, the original ground is relatively flat, or the original ground itself is the door position is relatively low, then in this case, as long as the water is used in the bathroom and the water is on the ground, the water will be found to flow towards the door, and when the door position can not stop the water, the water will enter the living room outside the bathroom.

Pay attention in the future: before doing waterproofing, you must first treat the ground, use cement mortar to raise the surrounding area of the bathroom floor appropriately, and let the water flow in the direction of the floor drain before doing waterproofing, so that after doing a good job of waterproofing, the water on the ground will not flow out.

Fill the tile gap first, pure cement, add water, it becomes a cement slurry, clear a little, let it flow like this, and then pour it into the tile gap, fill the tile gap, each one should be filled, especially the side of a circle, and then wipe it clean, the next day on the line.

From it, although it costs a little money, but the developer's waterproofing can only be said to be a kind of house inspection standard, mainly you did not do the water avoidance test when you inspected the house, and you don't have to be so troublesome to find it early, but it has been like this, not only affecting you personally but also affecting the relationship between residents, which is not worth it
