What would be the usual course of action for remedying a bridged DPC in Victorian property with later concrete floor? I believe that's what I'm dealing with, haven't looked in to sorting it out much yet. Obviously taking the floor out might work, but that's quite a scary prospect.
Polygon-
So the interior floor is concrete and you think it's bridging the DPC?
I obviously haven't seen it in person so it's hard to say for sure but I'd be looking for another cause to be perfectly honest.
If the foundations are ok (this can be an issue in Victorian properties as sometimes they are very insubstantial) then the ground under the floor should be dry. Is the damp problem limited to one part of the wall or all of it? Care to post some photos?

I can't offer you a recommendation but I would give you the following advice; damp is often classified as rising damp as some sort of great catch all when in my experience this is often not the case. Getting rid of damp is a process of elimination to narrow down, then find the cause and finally come up with a strategy to put it right. Get a number of people to evaluate the problem and immediately discount anyone whose first instinct is to inject a chemical DPC or put some kind of sink hole in the exterior wall as in my experience while there is a place for these treatments they should not be the first port of call. Also do not listen to anyone who uses an electronic damp meter.
