In my new house, in the bathroom, the developer has already done waterproofing, how to consider wate

Developers generally use steel waterproofing to do waterproofing, and there is no problem in using it in the short term, including the closed water test, but after a period of time, the building settles, and the floor deformation caused by vibration will destroy the waterproof layer and produce cracks. Renovation companies generally use flexible waterproof mortar, which has a certain elasticity and can resist the destructive force caused by the deformation of the floor slab.

Also because the decoration company is stationed in the beginning of the decoration, it will slot the bathroom wall to run water and electricity, and the local sewer may also be transformed, which will destroy the waterproof layer, so it is necessary to redo the waterproofing. Even if the bathroom doesn't do anything, the property will not give you a waterproof warranty after you issue a decoration permit to enter the construction, because you may bump and damage the waterproof layer during construction, so the property will not be responsible.

To sum up, waterproofing the bathroom of the new house is a must. Generally, the ground will be all done, the position of the wall shower is meters, and the wall meters in other places, but if the budget is sufficient, it is best to do the meters on the walls, which can effectively avoid moisture invasion, because I have been decorating for more than ten years, and I have seen a lot of walls separating the bathroom from the bedroom, placing a wardrobe on one side of the bedroom, and black mold on the wall behind the wardrobe.

There is also a door stone at the door of the bathroom, distinguishing the bathroom from the outside of the ground material, generally after pasting the bricks and finally installing the door stone, but it will form a waterproof layer gap, resulting in moisture invasion, the outside is the floor tiles are good, if the floor is a long time will produce a bulging phenomenon, the general owner will think that it is the water sprinkled when using, in fact, it is caused by the moisture under the floor tiles. Therefore, generally better companies will install the door stone first, then do waterproofing, and then lay tiles. It's cumbersome and labor-intensive, but it will work better.

The kitchen can generally not be waterproofed, because there is no floor drain, and there will be no large area of water, but the owner can also do it if he asks for it, which is of little practical significance.

Hope it helps.

In fact, according to the general use of the bathroom, after the bathroom waterproofing is done, the waterproofing of the kitchen can be done or not, but in case of use, the kitchen is also done, just when the kitchen is decorated, before pasting the tiles, the waterproof will be done, the key is to do a good job of waterproofing to try the effect of waterproofing, do a "water test", the construction unit understands.

Waterproofing you can't see He won't let you see Generally under the floor tiles If you don't feel at ease, you can fill the water test Plug the floor drain Add about 1CM of water on the ground and wait for half an hour If there is no leakage, there is no problem Try not to do this kind of experiment The developer's waterproofing is generally no problem.

The toilet has been done or should be tested for water injection, and the bathroom should be filled with water for 24 hours to see if there is any leakage. Waterproofing is generally not considered in the kitchen. When laying water pipes in the bathroom, it is recommended to walk the façade wall and not lay it under the floor tiles.

The waterproofing of the bathroom is best to be redone, if there is a floor drain on the ground in the kitchen, it can be waterproofed, and if there is no floor drain, it is not necessary to do it.

It is recommended to do it again, with water leakage and waterproof polypropylene cloth construction, it is recommended to find a professional waterproof to do.
