The water storage depth of the water storage test should not be less than 20mm, and the water storage height is generally 30-40mmThe water storage time is 24 hours, and the water surface does not drop significantly to be qualified 。This test is generally done on the roof, bathroom or room with waterproof requirements.
In the early stage of the water storage test, it should be inspected downstairs every 1 hour, and every 2-3 hours in the later stage. If water leakage is found, the water storage test should be stopped immediately, the waterproof layer should be re-improved, and the water storage test should be carried out after the treatment is qualified.
Just find some fine sand or dirt to use outside – just clean up after the closed water test!
Yes, theoretically, it can be effective.
The main test is to test the waterproofing of the bathroom and kitchen, and if there is a leakage within 24 hours, it is necessary to prove that the waterproof is not done well.
Check if there is a water leak downstairs, if there is no water leakage, it should be caused by evaporation, and it has nothing to do with water leakage!
It depends on whether there is dew downstairs, if there is water seepage, it is not okay, 2 mm is actually nothing, but look at the lower wall.
