What is the inspection batch for bathroom waterproofing?

The common method of bathroom waterproof inspection is to do a closed water test after the waterproof layer is completely dry, and the main purpose of the closed water test is to check whether there is any leakage in the waterproof construction and whether the waterproof function is normal.

The specific practice of the closed water test:

1. After the waterproof construction is completed, the closed water test can be done after 24 hours;

2. Temporarily block the floor drain and the perimeter of the pipeline mouth;

3. Build a 20CM high retaining wall at the door;

4. Start to store water, with a depth of 5-20 cm, and mark the water level;

5. Water storage time 48 72 hours;

6. After the water is closed on the first day, see if the water level has dropped significantly, if so, please check whether there is leakage around the roof and pipes downstairs in time, if not, continue to close the water;

7. On the third day, the water is closed, and the downstairs ceiling and roof pipes are fully inspected.

8. Carry out the next process after being fully qualified.

The 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 30-100mm, the water storage time is 24 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.

Toilet waterproofing is the quality acceptance record of the inspection batch of the coated waterproof layer. It belongs to roofing engineering.

Name and number of construction execution standard Construction Quality Acceptance Code for Building Decoration Project GB50210-2001

Do a closed water test, after the waterproofing is done, the irrigation water does not pass the waterproof layer, keep it for 48 hours, and observe the leakage of water. The leakage of the horizontal plane should not be less than 2mm

The inspection batch form "Isolation Layer Inspection Batch Quality Acceptance Record Form" for waterproofing and isolation layer in the ground floor belongs to the ground sub-division of the building decoration and decoration division in the grassroots sub-project, which is located in the "leveling layer inspection batch quality acceptance record form" after the isolation, waterproof layer in the middle of the leveling layer and the surface layer. Generally, it is not felt that it is a real grassroots, so it is difficult to determine which sub-item it should belong to, and there is no separate item for the isolation layer in the unified standard for acceptance of construction quality of construction projects (GB50300-2001), so it can only be understood to the grassroots. And it is also a grassroots level.

Look at your bathroom has a base layer, most of which are base layers, waterproof layers, and 2 inspection batches.

After doing a good job of waterproofing, wait for it to dry thoroughly before testing the waterDrain the water for a few more days. Go down below to see if there is any water leakage.
