Rising Damp on a retaining wall of an old cottage

[1Davehiggs]

This is causing a real headache for me, i have a retaining wall that has rising damp, the cottage was built on a spring and has no foundations (1754) the external walls are brick and lime,the internal wall seems to be some type of concrete although i'm not sure what is behind that ( brick and lime maybe), however when the wall was plastered some years ago, it was plastered in a normal plaster, this has generally fallen off due to the damp, I have taken this plaster off down to the bare concrete.I am in the process of drying the wall out and then to get some prevention and then re-covered. I am happy for a temporary measure at the moment as the whole house needs all the walls stripping and redoing correctly as the original plasterer did not use a lime based plaster when doing about 12 years ago.
My question please
1, should i paint with pva and then replaster with lime based plaster, artex, suggestions please.Is there another way i need to tackle this, I have thought about plasterboard , but I'm worried this might simply trap the damp behind it.

Can I ask how you know the house is built on a spring ? Was this perhaps a comment from someone in the damp-proofing industry as I have read this is frequently used by them ?

Logically I find it unlikely that an old house would be built on a spring . Our ancestors had much greater awareness of the soil than we do, the builder would have been local ( maybe the oriinal owner ), and any spring would, of course, have ben valuable in its own right. ?

I think the house could have been built on a spring as it's name is pump cottage and it used to provide water to the village.The soil is clay and i am in Lincolnshire, I do agree that our ancestors seem to know where to build as my house and a few other old houses are the only ones that don't get flooded . thanks for your comments
