I have an Edwardian house, which has had a couple of extensions over the years, (previous owners, possibly the 70's or 80's). I am getting damp issues on one internal wall between study and lounge, (extension). The room in question has a concrete floor, I have removed the skirting board and the plaster goes straight to floor. Using a moisture meter I am getting readings around 20 at the bottom of the wall, halfway up, I get 7. I have removed some of the plaster at the ground level and there is no DPC. The wall in question is 12" thick, so I suspect may have been one of the original outside walls.
Any suggestions as to a course of action? What about a chemical DPC injection?
