Repairing victorian quarry tile floor

[Unregistered]

hello,
I have a victorian quarry tiled floor on lime mortar and no dpc with around 70 deteriorated/ damaged tiles (6 x 6 inch) that need replacing, most of them in 3-4 areas rather than dotted about randomly. Trouble is that under the existing tiles is about 6 or more inches of what appears to be lime based mortar, very crumbly and not a suitable base for retiling. I am assuming I have to get this old mortar out, my question is how to I get a suitable base for retiling to allow replacement (reclaimed) tiles to bond? i.e. what can i use to fill in the gap left by removal of the old mortar. My intention is do do any basic non-skilled work myself to to get the floor to the point where I can get a local tiler in to do the tiling & grouting. Following that I will get the whole floor cleaned and protected. thanks in advance for any advice.
Pete

you could end up causing more damage .so making the job more exspesive to put right .get a pro tiler to do all work needed.if its a case of money .then get it repiared in stages.

Hi Pete, as Ray above for me, any pics? 6" sand and cement sounds very strange to me.

hi,i havent seen your job but its by no means unskilled in any aspect that includes the prep.
i would advise a pro who specialises in this type of work to do the job for you from start to completion......someone like phil hobson,tenchman or tj from here are the main names that come to mind

hope this helps

If you have a lime bed with no dpm this was used so as to work with quarry tiles to allow the floor to breathe there for getting over the damp issue that may occur as there was no dpm used when the floors was installed.
If you do the work and dont put it back as previousley done then you will risk the chance off damp showing in those areas and possibly spreading.(if you havent put back a substrate that allows it to breathe) Also when the job is finished and you have said you want it to be sealed, you have to be careful on the choice off sealer used as the tiles still need to breathe!

You really need a pro in who has experience in this.
