Failed floor - is this an option? - Tile Advice

[John Benton]

Been to do some 'cosmetic' work on a floor today.

When I got there, cracks all over grout but no broken tiles. Most sounded hollow when tapped and suspected dot n dab. Question is, the method used for failed uncoupling mats (resin injection) would be an option. Not seen this before so not sure of the process. When I took the cracked grout out I could see a void of about 10mm to floor, confirming my suspicions. Would the resin injection method work on a void that size or only on a fraction of that. I'm asking this as the whole floor would have to come up otherwise. The kitchen units and large island are also fitted on top so it will be expensive to remove as its about 65m2.

Any input would help cheers

Is it a wooden floor or screeded

Sounds like a bad install, and at 65m2 I can see why your looking at resin injection. Are they expensive tiles as you would know the best option if dot and dabs would be a complete rip out and new install.

Sorry Andy its a mixture of timber and screed

It is without doubt a bad install, and the guy who did is no longer in the country apparently!!! They look like £25-30m IMO. The customer knows after what I've told them today that it really should come up, but I've guessed at about £7-8k minimum to do it right, hence me asking the question.

I think trying to fill a void of that magnitude would end up more expensive than taking the tiles up and replacing them. That said there is not reason why the resin injection method would not work.

Sounds like a recipe for disaster if the grouts cracking then surely its just a matter of time before the tiles come loose or crack....

I don't know of any companys that do the resin but might be worth finding one that may give further advise whether it can be done or a rip out may be necessary.

Not sure how much the resin will fill John, maybe a call to Dural or genesis? I had two failed mats and I think they are now resolved now Good luck and thanks for the testimorial.

What depth/ thickness can the resin be injected to Alan?

Just a thought......if they go for injection method......and it fails? Will they ring you??

Ostensibly it can be any depth. It becomes an issue with cost though. A typical 2pack epoxy resin bonding agent would be in the region of £50 to £70 per 5kg unit. 5kg will not cover much so i think it would be very expensive to inject a whole floor.

There would be no reason for it to fail. It would be a bit like restocking the tiles with flexible araldite glue...

 

[John Benton]

I think it might be worth a call to see if someone is willing to have a look and offer an opinion on the floor and see if a. it's feasible and b. cost effective

If it was me i would give them the number of the firm who does the injection, wish them luck and walk away.
