About the problems of the builder and the homeowner caused by the leakage of the bathroom and kitche

Responsibilities can be analysed as follows:

First of all, for the treatment of water leakage, water leakage must be repaired where the leakage is, especially for serious water leakage. This is called "plugging the leak". The real waterproofing lies in "prevention".

After the leak plugging is completed, in order to ensure the integrity of the waterproof layer, a layer of waterproofing is also required. And after doing it, it is necessary to do a closed water test to ensure that the water depth is more than 2 cm, and there is no leakage for more than 24 hours. After passing the water test, the owner must sign before handing over the house, otherwise the house cannot be delivered.

Whether it is a commercial house or a resettlement house, it is the same. If a problem is found, the owner must accept and sign before handing over the house.

Second, for the waterproofing problem in the decoration. As mentioned above, "to ensure the integrity of the waterproof layer", the installation and modification of water and electricity must nail the waterproof layer, perforate or slot, which is the destruction of the waterproof layer, so as long as the decoration involves projects such as water and electricity change, it should be redone after the water and electricity are done. Otherwise, it is equivalent to not doing waterproofing.

At this time, if the decoration unit suggests that the owner do it but the owner does not do it, it is the responsibility of the owner to leak after the decoration, and it cannot be regarded as the responsibility of the construction party who built the house, nor is it the responsibility of the decoration unit.

In addition, the kitchen is also a place for water activities, and the national standard of architectural design stipulates that the kitchen floor should be waterproof and the vertical wall should be more than 30 cm.

First, waterproof standards: the bathroom waterproof floor is all done, the wall is 1800mm high, the kitchen waterproof floor is all done, and the wall is 300mm high; Waterproofing should be painted 2 times, the first time to dry and then the second time. If it is waterproof according to this standard, and there is a leakage point in the closed water test, you can make up the waterproof at the leakage point, and then do the closed water test again to pass the leakage; If there are multiple leakage points or leakage water in a line and surface, it means that the waterproofing is not done according to the standard and is seriously unqualified.

Remember, whether the waterproof is qualified or not must be done in the closed water test. Qualified!

Second, the construction party re-did the waterproofing and passed the 48-hour closed water test, and the homeowner should accept it. After the decoration, if there is no water and electricity renovation and other behaviors that destroy the original waterproofing, there is no need to re-do the waterproofing, and the brick decoration can be done directly. If there is a water leak in this case, the cause should be ascertained and the responsible person should be identified

1. Most people think that there is no water leakage before the decoration, and there is leakage after the decoration, it must be caused by the destruction of waterproofing during the decoration, but in fact, if the cause of the leakage is found to be the quality problem of the waterproof coating and waterproof mortar itself or the settlement of the house, the responsibility should still be borne by the construction party.

2. If the cause of water leakage is found to be caused by accidental destruction of waterproofing or improper use during decoration, the responsibility shall be borne by the homeowner.

Another little knowledge tells you: waterproof materials are divided into waterproof coating and waterproof mortar, and waterproof paint should be used for home decoration waterproofing! 1) Waterproof coating, which is flexible and waterproof, forms a waterproof membrane after brushing, has a certain toughness, and can resist general bumps and fine settlements.

2) Waterproof mortar, which is rigid waterproof, similar to cement mortar after painting, is easy to damage and fail in case of large bumps and settlement waterproof layers.

The water leakage in the process of delivery should be continued by the builder to rectify, not local treatment, should be the overall waterproof treatment of the bathroom After rectification, it is necessary to carry out a closed water test for more than 24 hours!!

If the homeowner thinks that there is no problem with the waterproofing of the bathroom and other places during the decoration process, and does not require the decorator to carry out waterproof treatment, then if there is a water leakage, the decorator has no main responsibility On the premise of determining that the original waterproof layer of the bathroom or kitchen floor is not damaged during the decoration construction process, the owner has the right to request the builder to rectify

However, as a decorator, the floor waterproofing test should be carried out before the floor tiles are laid in the bathroom or kitchen, which is a matter of common sense and has nothing to do with whether the owner pays for this project. If the bricks are laid directly without this inspection during the decoration, there is a suspicion of destroying the waterproof layer during the decoration process

I've said so much, you should know how to do it

First of all, the waterproofing should not be treated locally if it is not done, and the waterproof layer between the kitchen and bathroom should be treated as a whole.

Secondly, after the waterproof layer is done, the closed water test should be carried out again, and the skirting board of the outer wall of the kitchen and bathroom should be checked after 24 hours.

Again, if you don't understand the kitchen and bathroom tiles, you don't need to do waterproofing from scratch. If all the tiles are replaced, waterproofing is required.

Finally, if there is a leak after the renovation, the responsibility is not very clear. There is no good basis for this. However, if the decoration does not have a waterproof layer, it should be the responsibility of the construction party.

As long as the decorator does not damage the floor of the bathroom and kitchen, such as slotting the drainage pipe on the ground. That's the property thing.

I think it's a property thing, just look for a property.
