What is the minimum water test height in the bathroom?

At present, there are many kinds of materials used for waterproofing in toilets, and the waterproof effect is basically very good. There are several areas of concern for waterproofing in the bathroom: the floor, the wall, the joints between the walls and floors, and the joints between the water and water pipes and the floor.

During construction, the owner will focus on supervising the construction details of these places.

1. The bathroom floor is waterproof and smoothed first. If you want to replace the floor tiles in the bathroom, after chiseling off the original floor tiles, you must first smooth the ground with cement mortar, and then do waterproof treatment to avoid leakage caused by uneven thickness of waterproof coating.

2 The waterproof part should be comprehensive. The floor and wall of the bathroom (with a return height of not less than 1 8m or full), the floor and wall of the kitchen and balcony (with a return height of not less than m), and all the floor and wall of the first-floor residence (with a return height, the ground and all walls of the basement should be waterproof and moisture-proof.

In addition, wall treatment is also important. In the general toilet waterproofing treatment, even the wall that is far away from the water flow and kept dry should be coated with a 300cm high waterproof paint to prevent water from penetrating the wall. If the walls of the bathroom are non-load-bearing lightweight, the entire wall should be coated with waterproof paint.

If two shower screens are used in the bathroom, the two adjacent walls should also be covered with waterproof paint; If a bathtub is used, the waterproofing of the wall adjacent to the bathtub should be higher than the top edge of the bathtub.

3 The seams should be painted in place. The joints between the walls and floors of the restroom and the joints between the water and water pipes and the floor are the most problematic areas. During the construction, the owner must urge the construction personnel to deal with these positions, and the waterproof coating must be painted in place.

4. The thickness of the waterproof layer should be sufficient. The thickness of the waterproof layer directly affects its waterproof life, and if the thickness of the waterproof layer is reduced, it is equivalent to shortening its waterproof life.

5 Be sure to do a waterproof test. After the construction of the toilet is completed, all the drains of the toilet are blocked, and a 25cm high "barrier" is built at the door"Then fill the toilet with water at a height of 20 cm and check the surrounding walls and floors for leaks after 24 hours. This 24-hour waterproof experiment is the key to ensuring the quality of the toilet waterproof construction project, although it is troublesome, but it must be done.

Generally, more than 2 cm of water is closed for more than 24 hours, and no leakage is qualified.

In fact, there is no specific requirement for the water level, the key is that the time must not be less than 24 hours, as long as the waterproof water level is recorded after the test is completed.
