Using grout to UNDER floor tiles!

[arniesacknooson]

Hi all, can you tell me if grout should ever be used UNDER floor tiles? Our bathroom fitter has dot and dabbed with adhesive but used only a few blobs so much so a couple of tiles have lifted under foot in a see saw action. He assures us that by pushing in a watered down grout they will be fine. Serious alarm bells are ringing in my head as I am under the impression watering down any such material will just make it weaker therefore leading to crumbling and breaking down. Is this tiler a noddy? Am I worrying too much or do we need to take him off the job asap? Any advice would be great!

Your tiler (I use that word loosely) is an idiot.
Tiles should never be fixed with blobs of adhesive and grout will never fill the voids.
I would turf him off the job and get someone who knows what there doing.

The thought he must allowed to sort any problems dos'nt bear thinking about....

You said he's a bathroom fitter!
He must have a leaning towards one element - tiling, plumbing, carpentry ...and perhaps you should ask which it is.
His answers to your concerns are not ideal and at this stage any loose tiles is a travesty of workmanship.

Take him off the job.

Hi thanks for reply. yes he is v.good at the plumbing side of things but as he was recommended by our builder whom had his bathroom fitted by him we presumed he would be excellent at everything!
