24-hour closed water test: waterproof guarantee of kitchen floor

Want to make sure the kitchen floor is watertight? Then try the 24-hour closed water test! This is the homework that developers must do before the house acceptance, providing you with perfect waterproof protection. So, how to do it specifically?

Preparatory work/about to start work

Make sure that the waterproof layer is dry for the specified time, and then prepare to start the closed water test. Remember to build a water stop with a height of 30~50mm at the door of the kitchen room, and block the floor drain tightly to form a small pool with a depth of 20~30mm on the ground.

Closed water test process

Next, let the water stay there for 24 hours. During the period, please ask the property department and the corresponding downstairs neighbors to check whether there are signs of leakage in the downstairs ceiling. If there is any problem, do waterproof layer or repair again, and then do closed water test until it is completely qualified.

Acceptance process

Finally, after laying bricks on the ground, repeat the above steps for closed water test acceptance. Don't worry, the workers will finish the process. You just need to check carefully according to the procedure to ensure that all parties sign and confirm.
