I had a concrete slab laid with an Aco Drain as part of a renovation a year or so ago, and now I'm ready to get patio stones down.

The image shows a 22m sandstone slab without mortar just to show the height issue I have.

Most of the house there is a wall the other side of the drain to to the patio. I guess where the walls are its not a problem that the slabs will sit higher than the Aco Drain? (The concrete slab has a 60:1 slope to the drain)

But what about where the Doors are, like in the image shown, do you think there enough room for 22mm stones?

(I've used a sandstone 22mm stone for example, I think we actually prefer a 22mm Limestone stone. Id prefer a natural product to porclein)
