What are the most common causes of water seeping downstairs from the upstairs bathroom?

There are generally two reasons why the bathroom leaks downstairs:

1. The water seepage of the floor slab is that the floor slab did not do a good job when making the waterproof layer.

2. The most common thing is that the waterproofing around the sewer pipe or the upper water pipe is not done.

The first problem is difficult to solve, to remove all the bathroom floor tiles, wipe the leveling layer, brush waterproof paint or pave the waterproof layer. The second problem is solved, just need to disassemble the water seepage around the pipe and make a waterproof layer!

This is because the waterproofing of their home is not done well, or the waterproofing is damaged, so it leads to the current water seepage. The reason why their house is dry is that once there is water, it will penetrate into the cement, and the water in the cement will only penetrate into your house until a certain extent. You can find an upstairs waterproof treatment, the cost is low, and the effect is still better.

First of all, you should start with the most basic and simple to see if there is a leak at the interface between the pipe and the ground, including all the devices that pass through the ground (running water, sewer, heating, gas, etc.). If there is leakage in these places, it can be consolidated and repaired; If not, it must be caused by the destruction of the waterproof layer of the ground, in which case the ground can be treated with a penetrating waterproofing agent.

The main reason for the upstairs bathroom leaking downstairs is that it is not waterproofed, or the waterproofing is not done well, and it should be redone.
