hairline crack, slight flex in 2 tiles - to foam or not to foam?
In short:
would using some expanding foam behind 2 tiles that have a small amount of flex, where I presume adhesive has partially de-bonded help fill the void and re-glue the to tile to breeze block?
Or inject some kind of adhesive/Silicon to where i can get to with grout removal?
The long:
Had tiling done in new bathroom 2.5 years ago.
Noticed a small hair line crack on sections of 2 tiles horizontals, scraped out partially and refilled - Now done this twice and see it's cracked again.
It appears there is a small amount of flex on two or three tiles inside the shower quadrant (row 4+5 from bottom, 61x30cm tiles), these back on to an outside wall (breeze block). If I push on the tiles hard I get about a 1mm flex and they move together and causes the grout to crack to open more and come out.
The other side is plasterboard and all seems solid.
If I knock on those tiles they do appear to be hollow, the bottom 3 rows do not sound hollow and I see no flex.
The shower quadrant door opens/closes, resulting in constant impact bangs on these sets of tiles, no doubt why the grout re-cracks after 4-5 months again.
Would removing the grout and shoving some expanding foam behind the tiles help bridge the gap and re-glue the adhesive?
Or try and get some Silicon behind it?
I would really to avoid having to dismantle the shower quadrant and making a big mess of the bathroom (damaging tiles etc) and unlikely get a tiler to even turn up to rectify.
I have used foam before for this situation once before on a door tiled door reveal and there was a similar issue, i injected it with some foam, re-grouted and the issue never came back. Has any one done anything similar with success?
I was going to use fisher general purpose expanding foam, is there anything that may stick better?
thanks
