Best Flexible Adhesive? - Tile Advice

[arpee]

Hi, can anyone help me select the correct adhesive for an external tiling job?

I am tiling an external terrace with a wooden substructure. Above the wooden sub-structure I plan to fit a waterproof moveable membrane (Ditra) , and tile over that.

It will be important for there to be minimum risk of water ingress through both the grout and the adhesive, and because of the wooden structure there needs to be maximum flex in both the adhesive and the grout.

The surface will also have an external drain fitted and we need to try to ensure minimum seepage of rainwater between the edge of the drain installation and the adjoining tile edges - I'll probably silicon around this area and tile up to it.

Tiles will be porcelain, 600x600, around 10mm thick, total area around 12 sq. meters.

Any suggestions?

Thanks in advance for your help.

Pretty much any flexible adhesive with these numbers in the smaller print

When you say ditra do mean ditra drain 8

Thanks for your help. No, its regular Ditra, not the drainage type. There is a fall on the balcony so I can get the rainwater into a standard plastic hexdrain and connect to a downpipe thats adjacent. I thought about the drain 8 but it seemed a lot harder to get the waste pipe to connect to the downpipe.
