I think my question has been partly answered by @Andrew near the very end of this thread, but would like to double check and ask an additional question.
I am not a tiler.
Situation (see photo)
100 year old terrace house. Front room appears to have original (or very old) quarry tiles on top of a thin base (not sure what), back room seems to be some form of concrete floor, age unknown.
Area has a high water table and damp floors and damp solid walls are the norm in this area.
We will be applying a chemical or liquid DPC to the walls but do not want to uplift the existing floor, but can increase floor height by around 30mm.
Many posts on this forum discuss various liquid DPM to be applied to floors, but in some threads (like one @Andrew contributed to above) someone gives warning about the need to keep the floor breathable.
This seems like a sensible way to proceed.
My proposed solution:
Lay new or reclaimed Quarry Tiles over the existing floor using some form of breathable mortar eg Hourdex.
We will also fit some form of re-circulating air system to extract dampness from the air.
I would appreciate comments on this or alternative solutions.
Any possible issues I have not considered.
Assuming we will be removing some plaster at bottom of all walls to apply DPC, is there any specific thing we should do when tiling up to the wall - before or after we replaster and add skirting board?
Tile sealer?
Obviously we do not want to completely seal the tiles. What should we apply to the tiles to minimize effects of liquid spills and to help maintain the surface.
