tiles or Platon on concrete slab

[Kristina J]

Platon or similar directly on the concrete floor in the basement, then foam insulation, and on top a laminate floor, seemed like a simple solution against moisture, but the more I read about how to lay a Platon floor, the more I doubt both the work and the cost. Would tiles directly on the concrete slab solve all the problems? Even when the concrete slab demonstrably draws up moisture? If so, it would be a cold floor, but better that than a moisture-damaged house. The concrete slab is uninsulated from the 70s. If someone could advise me, I would be grateful.

Both constructions work well? if you place platon as you should with ventilation in the baseboards. We have laminate flooring on foam boards with a platon membrane underneath, with waterborne underfloor heating in the foam. Works excellently but we had no moisture at all in our slab when we checked it, although. Tiles, as you wrote, are cold to walk on, but so is laminate without underfloor heating, probably even if the foam insulates. Otherwise, tiles handle moisture migration well, so it's a good option in such a basement.
