i will be placing aggregate, ready for DPM and pouring a new concrete slab. how should i go about overlapping the DPC within the block to my DPM? Put the DPC behind the DPM or in front, and under my concrete pour?

I’ve finished reducing the levels of my groundfloor, and ready to lay hardcore, concrete slab and then insulate before laying the UFH pipework. However i’m unsure how i should be dealing with the door threshold that is a cavity. As my concrete slab level is higher than the internal leaf. The required level for slab is top of wood in photo. How should i go about avoiding the cavity from being filled with concrete? And getting dpm fitted correctly.
