After three months of renovation, the exterior wall of the bathroom began to seep water, which was u

Don't be in a hurry, this situation is very common: generally for three reasons.

1. The water pipe in the bathroom burst and seeped outside. (This situation is the least, generally will not leak) 2, the bathroom faucet is not screwed (remove the faucet, re-wrap the tape, and screw it) 3, when the outside is tiled, the water shade on the ground goes to the wall, resulting in mold on the wall. (This is very common).

Inspection method: (elimination method).

1. Check whether the faucet is leaking first. Whether it is not tightened.

2. Suppress the entire waterway. See if the pressure is dropped.

3. There is no problem with the water pipe, that is the matter of the wall. Wait for a period of time to dry, re-approve the wall, and paint it.

I don't know where you are, if you are in Dalian I can solve this problem for you.

Water seepage is mainly caused by unqualified waterproof and waterproof materials, generally the cement number is not qualified enough, and the waterproof performance of waterproof cloth and ceramic tiles is not good.

The only solution is to cut off the tiles and re-do the waterproofing.

I don't know which city you are, it seems that the craftsmanship of various cities in China is not the same, but according to the foreman of our family, if the amount of seepage is too large, it is because the pipeline is leaking. If the amount is not large, it is most likely that the cement number is not enough and the waterproof material is unqualified, there is only one solution, dismantle and redo, and the sooner the better, otherwise there will be endless troubles. Good luck.

It may be the reason why the waterproof layer is not brushed for you, which is more likely. In addition, it is necessary to analyze the situation on the spot before drawing conclusions!

Where are you? Judge according to the actual situation! And I don't know about the original design of your house
