My sister-in-law has bought a house built around 1960. Due to the family growing, a room needs to be created in the basement (potentially a bedroom or children’s room). There is currently a hobby room down there with a wooden ceiling and wooden panels on the walls. In other rooms, the basement wall is damp – what we will find behind the panels remains to be seen. I also expect a damp wall here. The house is scheduled to be insulated from the outside soon – above ground level. The basement section protruding from the ground will be included in this and will be wrapped in a vapor-tight insulation layer. Now the question concerns the basement wall that is below ground level. I would recommend excavating outside, applying a clean waterproofing and insulation, and sealing the wall against the floor slab using an injection system. Due to financial constraints, my sister-in-law assumes the room will need to be waterproofed on the inside to make it suitable for living. The moisture would then remain inside the wall. The building material is currently unknown; we are trying to find information in the old documents.
I would like to hear your opinion on this. We expect that whatever solution is implemented should last at least 20 years.
Best regards,
Roger
