Does the cast in place floor bathroom need to be sunk?

The kitchen and bathroom are not a use unit, the kitchen can be leveled if it is low, and the kitchen can be kept on a level with the floor of the living room, but the bathroom should be slightly lower than the height of the floor of the living room and the corridor, which is not only due to drainage factors, but also because of the status of the bathroom itself. >>>More

The steel bars of the lower city toilets do not need to be driven into the walls.

Did you hit the wrong unit, 400cm is 4 meters? There is a sinkhole in your bathroom, the settlement is so serious, simply tie the steel bar on the bathroom floor to make a layer of concrete slab, even if the bottom is empty, it will not affect anything.

It is not recommended to use, the bathroom backfill has a special backfill material, the bathroom structure belongs to the sinking type, the caisson is too heavy will affect the structural problem, it is not recommended to backfill with construction waste, it should be a special bathroom backfill material. Hope it helps!

Generally, it is backfilled, noiseless, firm and reliable, and the backfill is also very simple. If the cast-in-place board can ensure firmness, and you don't care about noise, of course, you can also use it.
