DPC Mortar - Look ok?

I thought it was there to catch the mortar droppings.

On an old 2” cab, with half inch of damp protrusions into the cavity from both sides and a tie wire helping catch the snots, a blocked cavity is a very real possibility.

When the cavity fill was 2 courses below damp and the inner skin was brick the cavity fill was often close to the DPC by the time the plate was going on and the snots off the ties had been knocked off.

They definitely built my old estate in the 1970s with "outie" DPCs, but my current house's 1990 extension has an invisible one.

I guess that at some point in the 1980s someone worked out that you could point over it without the world ending. Plus this way you don't get the crumbly bits above and below as shown in the photo in this thread.

Arguably the outer skin's DPC is hardly necessary anyway, the brickwork above gets pelted with driving rain so it's fairly pointless, and it may even trap moisture above the DPC by preventing it from wicking into the ground. Perhaps using a wider "outie" one on the inner wall could be a sensible precaution though, where appearance doesn't matter. But if protruding inside the cavity it could catch dripping condensation and hold it against the wall.

The bumps in it stop the house sliding away! You'd need a heck of a sideways force to lift the entire house by the 1mm needed to clear the bumps.
