Anonymous users2024-01-21Hello! I don't know why you would ask such a question, I think under normal circumstances, as long as the workmanship is in place and the operation specifications are done, the cement floor will basically not crack. Of course, the so-called "concrete floor" refers to the concrete poured with stones, not only cement and yellow sand.
At the same time, the ratio of concrete must be appropriate, and proper maintenance should be carried out in the later stage.

After understanding the waterproofing of the balcony, let's take a look at the waterproofing practices of the kitchen. The waterproof height of the kitchen is 30cm 50cm, and the wall waterproof can also be made with a layer of waterproof mortar and then a layer of paint waterproofing on it, and the coating can choose polyurethane waterproof coating or water-based polymer waterproof coating or other waterproof coatings. If the kitchen is a dry area, there is no need to do waterproofing, plus the waterproofing has been done when the civil construction is handed over, as long as the water pipe is made from the wall as far as possible without damaging the ground.
If the exterior wall structure is damaged during the decoration, such as thermal insulation layer, exterior wall coating, etc. (they mainly play the role of waterproofing), it is recommended to do waterproof coating on the exterior wall, or use other ways such as laying wall tiles. If it is not the above problem, then it is likely that the wall and ground near the balcony are not leveled, and the balcony floor next to the room is lower, so that the water cannot be discharged in time after the rain, which causes the water to flow into the room. >>>More
