Just find some fine sand or dirt to use outside – just clean up after the closed water test!
There is no strict requirement for the height of the water test, cover the mouth of the sewer pipe, and it is almost two centimeters above the ground. Keep it for 24 hours, and see that the top surface of the downstairs is not leaky. ，
The bathroom did not do a good job of waterproofing, and in principle, it had to be smashed and redone. There is an economic loss for sure, and it will be higher than the cost of renovating the bathroom for the first time, because the master in the industry would rather take the work of decorating the rough house than taking the work of repair. As for the damage to the structure of the house, as long as the construction is reasonable, the use of electric hammer instead of real hammer will not cause damage to the structure of the house. >>>More
Bathroom waterproofing is not a separate ground waterproofing, and the wall should be rolled up with a waterproof height of not less than 200mm. If you do this, you won't have to do this with your walls.
If water leakage is found, stop the closed water test immediately, re-do the perfect treatment of the waterproof layer, and then carry out the closed water test after the treatment is qualified. >>>More
