You're talking about plastering walls and floors.
It's a quality issue.
It's not that the structure is not a problem, so don't worry too much.
Ask if other owners have the same phenomenon, and if so, it is better to join forces, so that the pressure on the developer is greater, otherwise one person will always be at a disadvantage to the developer. That's a word of thumb!
First, the expansion gap between the floor tiles and the floor tiles and the surrounding walls is too narrow, and when the room temperature changes drastically, the floor, cement layer and ceramic tiles will appear thermal expansion and cold contraction. If the gap is too thin and there is not enough space for the tile to "stretch", the tile is easy to arch, which is generally easy to appear in the northern region, while the south is not easy to appear due to the high humidity and small temperature difference. >>>More
If there is a hollow drum, it can't be said to be normal, it is a problem that they did not do a good job of waterproofing at the beginning, and they can ask the other party to rectify it.
If you are an all-inclusive decoration company, you will find them, and if you ask someone to buy the materials yourself, you will not find anyone else.
There are no bounty points!! 1 one-fifth of the hollow drum of course first to the bricklayer or decoration company to complain 2 hollow drum because the cement under the uneven paving, or the bricklayer cut corners and is reluctant to put more cement yellow sand, so, when the material is enough to repave, there will be no more hollow drum. >>>More
