Hello

I wonder if anyone has a good solution to my question!

The house is located on a slope with two levels and a height difference of 1.2 meters between the levels. There is a foundation wall that was previously built outside with 20 mm foam, 28mm battens, and three-ply board.

No visible moisture problems at demolition and now when it is exposed, but I wanted to tear everything down to remove the three-ply board.

I have now started building up with Platon membrane, 28mm battens, OSB, and gypsum. The Platon membrane will only be sealed at the bottom to the floor since I have a leveling floor and don't want it to draw false air. It will, therefore, be able to breathe upwards and sideways.

The house stands on blasted rock, on a slope with bedrock underneath. When I chiseled under the slab, the crushed stone was bone dry.

I wonder if I've thought completely wrong? Does anyone have tips for a better solution?

  • Blue dimpled membrane installed on a wall with visible insulation and wiring, part of a renovation project to address moisture concerns.
  • A concrete wall with a new blue Platon membrane partially installed, visible cables, and a hammer on the floor in a house under renovation.
