Question from Isabelle:
>Answer: isolate by the ground
Hello, the solution best suited to your concern for humidity in your apartment located above a wet cellar would be to act directly on the floor of your apartment. If it is parquet, it should first be removed in order to install an insulator in plates or strips, resistant to weight and pressure (polyurethane for example). Over this insulation, you can place the coating of your choice. If you have a concrete slab under the existing floor, you will then have to stick an insulating sheet and then have a plastic film to protect the insulating material, pour a screed on it and finally place the covering of your choice.
