Where does the house need waterproofing?

The main waterproof parts are bathroom, kitchen and balcony.

1, toilet

The bathroom wall and floor, the bathroom belongs to the water-intensive area, so it must be waterproof, and the wall should be about 2.4m to prevent water leakage and other related problems. If the bathroom is a second-hand house decoration, it is recommended that the self-built wall be waterproof to the top; It is best to use ceramsite and fly ash for toilet backfill, which is light in weight and good in water absorption, and do not use construction waste and soil.

Step 2: Kitchen

Kitchen waterproofing is mainly floor drain, floor and wall treatment.

3. Balcony

Balcony, especially open balcony, must be waterproof and drainage, because rain may float in to avoid water seepage, causing neighborhood disputes and maintenance troubles. If it is a closed balcony, it is recommended to be waterproof if you hang some clothes at ordinary times.
