Hello all

I have a query on damp course. Our house is late 60s and the damp course is protruding slightly in the form of dried up blisters in a lot of places. Has anyone seen this before/ know why it might be doing that? I’ll try and add some photos, thanks

Hi dand
This is not unusual and nothing to worry about.
