Help me with repeatedly floor cracked tiles PLEASE - Tile Advice

You should expect any building to expand & contract with changes in temperature and humidity .think of it as a living entity..it has to breathe to survive..it it didnt it would eventually fail..these contractions and expansions are minute but happen in all structures no matter what they are made from.
Has a flexible floor adhesive and grout been used to secure your tiles ?
Although I have never suffered this problem after an install I have had grout break out due to excessive movement of the sub floor..next time your tiles are replaced ensure a ' super flex ' adhesive is used and possibly a flexible ad mix to boost the flexibility of the adhesive..the install I had problems with I used both, a super flex tile adhesive ( powder so you can mix it yourself & add the flex additive ) and same for the grout. This route solved the issue I had and hopefully will resolve those you are having

Thank you very much for your time..I will do this

Tiler most probably hasn't prepared the floor correctly, an uncoupling sheet/crack mat should have been installed to prevent cracks forming due to movement of the floor. In my opinion needs ripping out and starting again from fresh.

Hi! I need your help again please. I'm due to remove this 3 cracked tiles which have cracked for the third time after having replaced them 3 times. I'm not planning to re-tile the entire floor but just the 3 always-cracking-tiles. What would you recommend to do? What should I install below those 3 tiles to prevent cracks forming, considering that the floor around it won't be touched? If I use an uncoupling sheet for them it won't be levelled in relation to the rest of the floor. What do you think?

a building has to breathe..by that I mean expand and contract as the temperature and humidity changes , any movement is only minute but they are built to do just that..they would simply fall apart if they didnt...I would suggest the sub floor below the tiles cracking is prob flexing moving slightly more than elsewhere and the tiles are fixed too firmly across that area so cracking.
Ensure a ' super flexible ' adhesive is used next time they are replaced. You could also add a flexible additive to give it extra flex ( make sure it's a powder mix not ready mixed out of a tub ) then you can use the additive to provide that extra bit of flexibility.
I've only ever had problems with grout breakup g out due to subfloor movement and although used a flexible grout , the sub floor movement was still too much so when re grouting used some additive..problem solved..you will probably find that your installer have not used a flexible adhesive because your sub floor is a concrete slab and unlike a timber sub floor , you dont expect it to flex / move in any way, whereas a timber sub floor can move / flex quite a bit..
Hope this

Tiler has most probably not used an uncoupling sheet/crack mat when preparing the floor for tiling, this prevents cracks forming from movement and settling of the floor over time. Please see attached photo of said matting.

you need to figure out why they keep cracking. they have cracked 3 times in the same place. something is happening to cause that. If you dont fgure hat out and fix it then youll simply end upwith tiles cracking a 4th time. .
