Because the basement is in a closed environment for a long time, it is easy to be damp and moldy, so protective measures must be taken when decorating the basement to avoid this situation.
The source of water in the basement is groundwater, which flows back to the basement through the basement wall and basement floor. Water can't evaporate and accumulate. In view of these two aspects, the treatment methods include basement wall, ground moisture-proof treatment and basement moisture-proof ventilation.
