I'm just starting to renovate a stone miner's cottage in Wales. What I've discovered in hacking off the internal cement render and raking out the very crumbly lime mortar is that the rubble stone walls are full of large voids and virtually not held together by anything at all! Many stones are just loose, so I have stopped hacking/raking until I can start repointing bit by bit in small areas. What i'd like to know is, will the act of repointing the walls with lime mortar be enough to stabilise and give structural integrity back to the walls, and, if I pour a concrete floor with dpm will this inevitably lead to water being driven into the walls?
