Moisture migration – old building rehab
So, I am currently trying to retrofit an old house given my grandparents. The biggest problem I have is with rising damp and damp slab, due to the absence of any capillary brak.
I am thinking of dealing with the damp slab by applying a dimple mat over it or Schluter Ditra. On top of that the finishing layers.
My question is: By placing a vapour barrier over the concrete slab I am encouraging the moisture migration towards its periphery? where it can make the humidity problem in the walls even worse?
Thank you in advance
