The lower ground floor of the house that I bought has damp that I am taking measures to remedy - stripping mortar, lime render, repaving stairs. The external ground is higher than internal than internal in the front bedroom. Trial pit revealed that the dpc is actually below ground and can't lower the external ground due to very shallow foundations on London clay :-( Back bedroom is same level as external ground.
Now, coming to installing flooring for bedrooms. The hallway is wood planks over floating floors on concrete. For bedrooms, LVT I read will be a suitable choice? But confused is it better to be glued directly on the concrete, or like the hallway, installing on a floating floor better? If floating floor, what are my ventilation/ insulation options for the void given higher external ground in one bedroom and both at the same level in the other bedroom. And so, Airbricks if installed will be right at the floor level causing water ingress?
