Gap between foundation and wrap
That's a water proofing hard'ish plastic called air gap waterproofing membrane, commonly referred to as dimple board. it's not a part of the vapour barrier and it's primary function is to stop water from the water table entering the foundation. It's is good practice to run that it up higher so that it's flush with the finished grade upon completion. The missing morter is actually a requirement to allow condensation for the space between the wood structure and the brick to dry or drip out in extreme cases. The builder will likely do nothing because any landscaping should always be sloped away from your house anyway. I'm from Toronto and see this stuff almost daily. I did have to look up the official name as everyone just refers to it as dimple board.
