Anonymous users2024-01-23After 18 hours of water testing, the water level drops by 2mm, which indicates that the waterproof is not done well and there is a leakage. The purpose of doing the "water test experiment" for 48 hours is to test whether the waterproofing is done well: if there is a decrease in water, it is not done well; If not, it means that the waterproofing is in place.
The reason for the appearance after 18 hours is generally that the waterproof layer is not completely bonded to the base surface, and there is a gap between the waterproof layer and the base surface after a long time of water soaking.

One of the drops in the water level is normal evaporation, and the other is that there is a possible error, two millimeters, maybe it was a reading when you first looked at it, and now it may be another reading if you change it in a different place and change it from a different angle.
To measure whether the water leaks or not, the main thing is to look at the ceiling on the next floor! Even if there is a water leak, it can be seen in 18 hours!

Because I couldn't see whether there was a water leak downstairs, after 72 hours of closed water test, I found that the water level had dropped by about 2mm, and I don't know if it was normal loss, so I wanted to ask the expert's opinion.
It's the weather lately.
2mm is normal loss, the general waterproof test is 48 hours, you have 72 hours, indicating that there is no problem with waterproof construction.
Is the longer the closed water test, the better?
No, it's too long to be accurately assessed.
If it is professionally waterproof, after soaking for a week without seeping water, then you don't have to worry about it. Generally, after soaking in water for 30 minutes, there is no water seepage, and it is basically fine.
The closed water test was fine, but the renovation was completed but there was a water leak - this situation is very common. Then the reasons for this may be the following: >>>More
The waterproofing is not done well, or when testing the water, the water is too full, beyond the waterproofing, the wall is dry, the water vapor is absorbed, and the wall is wet, and the concrete will absorb water after six months of solidification.
First of all, the ground should be level, and there should be no trachoma. Floor drains, wall corners, pipe roots and other joints should use a flexible waterproof coating with high elasticity, and the joints will be displaced and are most prone to water seepage. >>>More
