I have an internal soil pipe in the kitchen which had leaked but is now fixed (hopefully).
The wall in the living room has developed rising damp and the wallpaper is coming away from the wall with a salty residue behind. We have concrete floors.
What is the best way to fix/cure the problem so that it wont happen again after we re-wallpaper the wall. Is there a way to do-it-yourself with over the counter products.
