I wouldn't be too worried about the sub-base drainage but I'd be very worried about that proposed build-up. It's a complete bollix!
75mm of mortar is NOT, I repeat, is not a sub-base. It's a layer of mortar. An unnecessarily thick layer of mortar, one that, at that depth, reaslly out to be a concrete , if it has to be there at all.
And then the plan is to top that with.....<drum roll>......40mm of yetrmore mortar!!! Why FFS?
