There is a property notice asking for waterproofing upstairs, but it has not been done upstairs yet. Can I grout at home now?

1, direct grouting will not cause much impact on the house, and it is one of the methods to deal with waterproofing;

2. Regarding the waterproof effect of grouting, neither the property management company nor the waterproof construction unit can guarantee 100%. After all, it is a remedial measure, not a formal and complete solution;

The upstairs owner has nothing to explain, and the whole responsibility cannot be shirked. If the property company does its duty of reminding, especially during the construction upstairs, the property company has no responsibility;

You have every right to ask the floor upstairs to be inclined and waterproof again. Theoretically it should be the same.

5, you can not let grouting, no responsibility, but in case of poor cooperation, it is yourself who is injured by water leakage.

The best solution is to do it again from the beginning upstairs.
