Anonymous users2024-01-23The closed water test, also known as the water storage test, should be filled with water, and the water should have a sufficient volume. The water storage depth of the water storage test should not be less than 20mm, the water storage height is generally 300-400mm, the water storage time is 48 hours, and the water surface has no obvious drop 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.
