I have some damp at the base of many of my walls downstairs. Most of the damp walls have concrete render with gypsum skin and the wallpaper had been painted with an impervious paint. In the photo the damp is mostly due to high ground levels on the other side of the wall as evidenced by the steps.
The ground levels are dictated by an adjacent building and would be difficult and expensive to lower. I'm thinking about either patching up and painting with a clay paint, or chipping the bottom 3 feet off, rendering in lime, then a lime skim over the whole lot using the French stuff that can stick to anything. It should be possible to make the other sides of the wall breathable too later on.
There are a couple of places where I have unexpected damp - under the stairs in an internal wall is one place. That's an earlier part of the building so it might just be no damp course combined with impervious coatings.
Any other thoughts or ideas?
