Hello
I'm about to renovate the basement in my house. Trying to figure out how to do it. I've read a lot of threads here, but I feel even more confused....:wow:
The house was built in 1952 and stands on drained but still old marshland, visible on the property in spring when the lawn partially becomes a swamp....
As far as I know, the house hasn't had new drainage installed. There's a drain water well in the floor of the boiler room where you can see a water level about 50cm below the foundation.
The basement is dry. No basement smell, I took down a hygrometer which shows 38% d^_^b
I intend to build a laundry room and a hobby room. Both should be more insulated than the basement is today. In addition, I'd like to have a nicer wall covering than the sterile cold plaster.
I'm considering the following ideas. In the laundry room, place tiles on the existing floor, frame the walls with metal studs, and use some form of non-organic wallboard to tile. The walls will be additionally insulated with Styrofoam.
For the hobby room, I'm thinking of doing something similar but with laminate flooring instead of tiles and a nice wallpaper on the walls. I'd like to insulate the floor a bit since it's cold.
I need tips on how to do this properly so I don't accidentally create a mold problem...
Best regards, Magnus

Hello
I am currently renovating my basement. The house was built in 1950.
What I chose to do is put tiles on the floor and plaster the walls with silicate paint. I drained the house about 6 months ago.
It may be that the reason it's dry in the basement now is that the walls can breathe well. It might get worse if you change that. A recommendation is not to insulate the inside of the basement walls.
Consider that the walls can breathe. Otherwise, there's a high risk of problems down the line.
What I was considering is installing a ventilated subfloor and then laying laminate or something similar on top of it.

Everyone has recommended me to insulate externally to achieve a dry interior wall, at least the walls that are below ground level. It works to insulate internally with a damp interior wall and non-organic material, but wallpaper risks becoming bubbly, moldy, and peeling. Instead, paint with moisture-permeable paint. Insulating externally, including new drainage, costs 1500 to 1800 /sqm basement wall below ground (calculate sqm including 40cm under the basement floor).
I would even say that it is a very strong recommendation not to insulate basement walls internally. You want the dew point on the outside, and any moisture should be able to dry.
Insulation on the outside and only non-organic materials are the only safe options in a basement.
