ONE of our forum sponsors , tilefix ,does something called adpeds , probably worth a look .

if you are dead set on it being more tiles you could also consider the outdoor pedestal tiling. If you are DIY'n this then it could save you dealing with adhesive and make drainage a bit easier also. I don't have any experience in this but i'm sure i actually seen some pictures that @antonio done?

Lots of good ideas, I like the pedastel solution, I assume it's more costly than adhesive though? My question though is I assume you can still grout with this method, so I can match with the internal tiles. If so, does this mean I can achieve the fall by adjusting the height of each pedestal for drainage purposes?

Tilefix do a filler material to put in before grouting with their adped system .

I am liking the sound of this system more and more. If anyone is aware where to locate 2mm grout backing rods then do let me know please. If not – do you think it would be easy to spot if I went with 3mm – assuming you can get 3mm…

If I can get away with laying a 40 sqm slab by hand then great, my question now is what is the minimum thickness I could get away with on the top of the crushed and compacted hardcore to take the weight of procelaine and light foot traffic whilst ensuring a level surface for the pedestals?

You need to contact tilefix about the information you are asking I they have a you tube video , porcelquick adpeds .

usually laying with pedestals
it is carried out at level, the slope must be under the pedestal.
otherwise they move.
I don't understand why the line is closed,
the ones I used start from 0.5mm thick and go to infinity ...

What do you mean by the line closed Antonio?

What do you mean by the line closed Antonio?

the width of about 5mm between one tile and another,
it must be empty to let the water fall into the area of the pedestals

Okay, Im erring on the adjustable pedastel system rather than porcelquick as it doesn't involve cement and adhesive. However, to create the inside & outside seamless look I would need to grout externally. I assume I do as otherwise the external tiles without grout would look like an unfinished job when compared to the same tiles internally with grout, unless anyone else would disagree.

I assume you can use the grout backing rod with the adped sysem too as with the porcelquick system??
