Injecting resin under lifting/moving floor tiles? - Tile Advice

[Koojo]

Hi guys newbie here this may seem like a strange question but you guys will no if it's possible or not?

I have a customer who's floor tiles a starting to come loose under foot the grout is coming away the tiler who
Did the job has'moved away' and will not honour the job. The customer states that the same thing happened to her in a property abroad and it was repaired by injecting resin?? Under the said areas ?? I have not heard of this before but she is adamant this is how they sorted the problem? The customer has the high gloss black flecked tiles and does not want them lifted and relayed? As she thinks this will be expensive they'll break she won't get a match(as tiles cover her whole down stairs living area).
can you guys advice on what she is sayin is true??

Many thanks
koojo

there are some videos on you tube showing similar methods as you describe and there are contractors around injecting floors around the uk at the moment ,what the success rate is I dont know and what guarantee if any you receive with this method

Heard a tiler once say he raked two sides of grout out and poured a very watery mix into the join and tapped the tile.. Had set the next day but for how long we will never know.

Any underlying reason why it's boast?

tile tenting is usually expansion !, so fix the problem first IMO

Tbh I'm not sure why they are lifting but the customer is not keen on them being lifted?? She is a lovely elderly old lady but I'm not sure I can help on this occasion with the resin fix?

I have done this before on a quarry floor that was laid on a sharp sand and cement that the builder had laid to dry ,he did not want to take the floor up so I mix a slurry of sbr and cement and pour it on the floor it did the job.

An epoxy grout will also work. I have a one liter vetinary seringe that I use to inject the mixture where 4 tiles meet, the corners. The seringe fits there just well enough. I inject as much as it will take, even if it rises through the cracks. It needs 24 hours to set. 40 hours in winter. The mixture should be just thin enough to make the injection process easy. You can get such seringes on the internet, AliExpress or Vetinary supplies. Other types from building suppliers are much more expensive.
