Amtico signature floor — flood damage action and advice

I have Amtico signature floor in a downstairs room.
The Amtico is laid on a solid concrete floor. The floor was professionally prepared and laid. The result was stunning.
Two weeks after the floor was laid a domestic water pipe burst in the ceiling and a large part of the room was flooded.
The floor was seriously wet for about and hour. The excess water was mopped up and the floor dried.
The plumber accepted liabilty.
Initiatially the floor seemed fine and we thought that was that.
After a month the floor bubbled by the doorway. The tiles were lifted in the affected area. The latex had broken up. This was replaced and new tiles laid.
After another month a similar thing happened in another part of the room. This was repaired again and everything seemed ok.
Now a further bump has appeared in a totally different place and I fear the same problem.
The areas that weren’t touched by the water are just fine.
The plumber has paid for all remedial works to date.
It seems clear that carrying on making piece-meal repairs is perhaps not going to be a satisfactory option in my opinion but I'm not an expert. Neither is the plumber.
Is piece-meal repair the industry standard approach?
I would be grateful to receive the guidance of forum professionals regarding where — perhaps the name of a trade association or another organistion — I can get an independent professional assessment of the damage and a formal report what should be done to correct it.
I presume that I'm now going to have deal with the plumber's public indemnity insurers and wonder if I should employ a loss adjuster to ensure that my floor is put back into the state it was before the flood.
Your help and guidance will be much appreciated.
Many thanks

Google Sid Bourne. He can inspect / report and is a recognised court witness for cases (if it goes that far).

 

^ again six Bourne. I'd say the moisture has got in to the floor which is causing your screed to blow so can only see you having more problems.

Got unlucky there. My Karndean floor in the kitchen has been flooded twice and is still down and ok. Can you remember what the latex screed was over?

 

my old fridge had a constant leak for ages, least a year, until I could be arsed and got a new one lol
the Amtico & screed (300hd) is still solid, however mc% readings are pretty scary lol

 

lol yeh, also been zapping everything with the temperature gun lol
my poor dog never got any peace the first night, and keeps trying to kill the laser dot as it's zipping round the room lol

 

I fitted a jewellery shop in in karndean da Vinci 70msq and three month later upstairs pipe leaked over weekend and the place was a foot deep in water all weekend . They got rid of wtervand dred up etc.. and tiles were fine. Three years later it is still spot on no problem at all. Maybe the problem is a subfloor prep problem ?.?.
