600x300 travertine wall tile on plasterboard - Tile Advice

[GoneGuy]

Hi all, been to a quote to put 600x300 travertine on walls in downstairs w/c.
I told customer I was concerned as the walls were plasterboard and I could not locate the battens behind the plasterboard.
Customer wants the tiles on the wall regardless.
Is there anything I could use like Wediboard etc as I know there will be a lot of weight on the walls with these tiles.

Customer living room has been done with similar tiles on plasterboard with tub adhesive By her dad and has had no issues.

Why would you want to locate the battens behind the plasterboard ?

How thick are the tiles.

 

[GoneGuy]

Was looking to see if there was battens so the plasterboard wouldn't peel off with the weight

 

[GoneGuy]

10mm thick

I was going to use powder.
Just read somewhere that plasterboard can only hold up to xxkg per Sq m

The plasterboard should show signs of being screwed to the wall via the studs.

Plasterboard limit is 32kg per mtr

I couldn't see any, so done a bit of tapping and it sounded really hollow and couldn't find the battens, so I was worried if I put all the tiles on the wall I would get a call in near future saying the walls have fallen

It's dot and dabbed then

If you are going to Tile it anyway you could locate battens by using small posidrive screw driver to check to see if there are suffient studs there . Once you have found first stud you should then be able to find others at 400 mm spacings . Unless as stated above it is dot and dabbed .

He said there's no sign of screws in the plaster board
