Anonymous users2024-01-24This phenomenon just means that the waterproofing is not good enough. This is because the grading of the screed layer is not done well when doing waterproofing. The specification requires that the closed water test should be done after the waterproofing is done, and if the closed water test is qualified, there should be no local water storage on the surface of the waterproof layer after the toilet is discharged.
The water seepage on the wall at the door of your bathroom is because there is water accumulation in the waterproof layer at the door, and this part of the water cannot be eliminated, and it is absorbed by the wall by capillary action, and the height is basically below 250mm from the ground, and it will spread to other rooms after a long time. If the sewage in the bathroom stinks, it will affect the whole room and have a peculiar smell. Therefore, I advise you to solve it as soon as possible, dismantle and redo it from the lower end of the bathroom wall 400mm, and dismantle it until the screed layer is re-sloped (slope floor drain, the slope is lower, and the already wet wall must wait for it to dry out, and the mortar or fine stone concrete of the screed layer must wait until the final setting period to re-do the waterproofing.
Then do a closed water test. The purpose of the closed water test is not only to see if there is water leakage or seepage, but also to see if there is local water accumulation. After the closed water test is qualified, it will enter the next process.
