Is the second waterproofing of the fully decorated room, kitchen, bathroom, balcony included in the

The "cement mortar" you are talking about should be to use the dry paste method to pave the floor tiles, so that the ground will be a few centimeters higher. If you want to make it a little lower, you can use the wet paste method to lay the floor tiles. It is directly mixed with cement and water to form a cement slurry, and then scraped on the back of the floor tile to bond with the ground.

It depends on how many years of warranty you have signed the contract with the decoration company, and the general company has a warranty of 1-2 years. You look for the contract, the warranty period is not the responsibility of the developer, do not deal with the local quality supervision department to complain, they are in charge of this matter, and then do not go to court to sue, otherwise the warranty period is self-care.

What should I do if the floor of the master bedroom is blackened due to leakage in the bathroom of the finely decorated room? If this is the developer's problem, you can find the developer, if you are looking for decoration, who do you look for for whose problem?

Sure, take pictures to keep the evidence, as long as the losses are reasonable, the general developer will take the initiative to compensate.

Does your contract cost include waterproofing? If there is no decoration company, it can be ignored, but it also means that the decoration company is not responsible for the work, and now there are some waterproof methods of surface conjunctiva, but they are all temporary, and if you want to do it for a long time, you must do it again.
