Not necessarily, I have two DPC,S. The bottom DPC is sloped in the cavity to carry moisture out via weep vents, the upper DPC is to stop rain splash soaking the wall.

Your patio level is what’s known as ‘level threshold’-there’s no step up into the house as there would have been traditionally. The lower dpc shown should be a continuous barrier all the way around the building, at that level,on both skins of masonry. A level threshold presents a risk that rain splash will affect the wall above dpc level (not having the standard 150mm clearance from ground level) & so an additional dpc is installed,extending a minimum 1m past the raised ground level & lapping down to meet the dpc lower down.

Bloody IPad, it does not matter which way I take photos it turns them around

Try putting the sketch against a wall, then take a picture.

It could be that the orientation sensor is confused.

It iCrapple does not always 'just work'.
