I'm after some advice really. I know NOTHING about DIY! We live in an old brick house built around 1830. We've been told that apparently it was the normal thing to do to line the floor with bitumen under the flooring to reduce the damp coming up through the floor. Unfortunately it seems to push the damp up through the walls instead. In the past the walls have been injected (these are old walls with no cavity) but the damp just seems to keep coming back (5yrs was the last wall injection and we need more work doing).
My question is: is it necessary to keep getting the walls injected or is it better to put money into removing the bitumen and re-flooring? Or will this not fix the problem in the walls? We have two small children and no money so we want to see what is the best longterm solution financially - we struggle to keep affording the wall injections!!!
Any help & advce would be gratefully received!!!
