Patio laying advice

[Círdan Falassion]

I will be replacing my old patio over the Easter weekend. I intend to put slabs on top of the existing patio which is about 4" of solid concrete. As long as I obviously keep the level of the new patio below the DPC, what should I bed the slabs onto? Just mortor, dry mix of sand/cement etc.

All advice appreciated.

Thanks
