Hi all,
A friend lives in an 1870s semi. The party wall is damp. We've tried all the basic stuff - the room is well ventilated and well heated, we stripped the wallpaper, let it dry out, and painted it. A year later, the paint is peeling. The damp is confined to a narrow band at the base of the wall. The wall is made of brick, with a 1/2" layer of lime plaster.
Is this a good case for an injected damp proof course? Is there anything else to consider first?
If yes, then am I right in thinking that this is what to do:
- hack off the plaster to 1 metre height
- drill holes and inject
- re-plaster (what with? cement render first then skim?)
Any thoughts?
TIA
