Help, waterproof leakage problem The bathroom did not do waterproofing in the early stage, now

1 All have not been waterproofed before, and the remedial steps are as follows:

1. Take it down in the sanitary ware, reinstall it, and pay attention to the connection with the sewer pipe must use auxiliary materials such as waterstops;

2. Remove the 3--5CM area around the floor drain to make a cement-based waterproof material.

3. Use chemical grouting to plug leaks, punch grout on the top of your neighbor's bathroom, or grout in the tile joints of the bathroom;

Fourth, use colored tile grout, do it on the existing gaps, and use cement-based waterproof materials or JS waterproof materials to do it in other places (nozzles).

Fifth, the materials can be bought in the construction market.

First of all, the grout in the tile gaps should be cleaned out, and then the waterproof material should be used to fill it, and the gaps around the wall should be dealt with together. Another important point is that the surrounding areas of the upper and lower water pipes and floor drains should be treated with waterproof materials. This basically solves the problem.

Chisel the old "between the upper mouth of the floor drain and the sewer pipe and the floor slab", connect the interface between the floor drain and the sewer pipe, and then use 1:1 cement mortar and 15% of the cement content of the alum stone expansion agent to make up, you can. It turns out that the bathroom waterproofing is the overall flexible waterproofing, and after moving here, "brush the joint and its surroundings with cement slurry and 20% of the cement content of alum stone expansion agent", which will not affect other places in the future!

In addition, the bathtub drain is useless, remove the bathtub, chisel the interface of the sewer pipe, first plug the nozzle and then use 1:1 cement mortar and 15% of the cement content of the alum stone expansion agent to make up, you can.
