Hi,
I have recently moved in to a 150 year old granite stone terraced cottage and have been advised by a damp specialist that I have rising damp on an internal solid granite wall.
The wall is 60cm thick and made with solid granite. It used to be the external wall but an extension was built 30 years ago, thereby making it an internal wall with the living room on one side and kitchen on the other. Th wall is currently plastered and painted. There are no current signs of damp on the walls and they are not wet to touch but the damp readings were high on both sides of the wall. The living room has never been heated well, the fireplace was closed off and the kitchen does not have a suitably sized radiator. The property is fully double glazed.
The damp specialist advised that I have rising damp as the wrong plaster has been applied to the wall. He advised the plaster draws in condensation which then migrates into the wall. He has advised I have a chemical DPC (injected) and then two applications of tanking slurry in order to resolve the problem.
As the wall is internal, and has been for 30 years, I am unsure whether this is the correct diagnosis so wondered if anybody might be able to confirm:
1) Is it possible for plaster on an internal wall to draw moisture out of the air and cause "rising damp" in solid stone walls?
2) If i remove the plaster, air the wall and heat the room properly over winter is it likely the damp levels might be reduced?
3) If the diagnosis is correct, is an injected DPC and tanked slurry appropriate for solid stone walls?
Any insight you can offer will be hugely appreciated.
Thanks!
