I have a customer that has had his shower tiled in crackle glazed tiles.
When the shower is turned on, water comes through into the hallway. Various tests have determined that the silicone seal around the shower tray is ok. The water seems to be going through the grout on the wall that the shower is attached to. The customer ran the shower again whilst the tiles were covered in polythene. Again, there was no leak.
He is not on good terms with his builder/tiler so all the questions I am asking cannot be answered.
The chances are that the walls are not tanked.
I do not know the substrate.
I do not know what brand of adhesive or what grout is used.
The tile manufacturer stated that the tiles did not need sealing.
I left the customer today, and asked him to do a water test on a spare tile. I am awaiting results.
My hunch is that the water is going through the grout.
These tiles are made in Tunisia, and are very expensive. Tiling the wall again will cost hundreds of £.
I was thinking of a regrout. If the grout came out easily I would grout with normal grout, and seal the grout & tile with Seal Guard. Or, maybe I could use epoxy grout?
What do you guys & girls think?
Thanks
Sean
