Default Contruction question

3 things that I noticed:

1. why they leave this gap in the brick?
2. What is that black fabric b/w brick and concrete wall?
3. I noticed that my builder has used that tape on the HVAC pipe in the garage are but when these go thru inside the house, they have not? shall I ask them to use that tape at all the joints?

1. Weep hole to allow moisture that penetrates the brick to escape. The flashing in #2 should be below the weep hole. It may be buried within the mortar joint.
2. Flashing to direct moisture out of the brick wall
3. Taping ducts in garage likely keeps expanding foam insulation from oozing into the ducts. Taping joints is not required throughout the house however.

I think one is a mistake - its too high up the wall to be a weep hole

What's A Weep Hole?

And I'd Be Scared If I Had A Gap Between Two Bricks, Is The Gap Permanent Or Can Be Fixed?

If that is a weep hole, you don't want to close it. It could cause problems.



This is a good picture that shows why they are necessary. You should have them at regular intervals on the bottom row of bricks, as well as above windows and above the garage.

There are certain situations where weeping holes can be in places other than at the bottom of the bricks. A picture taken from farther back could give us a better idea of why the weeping hole is where it is.

I was thinking the foundation wall has a brick shelf (similar to the posted diagram but deeper) and the flashing and weepholes were started at the top of foundation as viewed from the inside. If it's a brick shelf with a reduced foundation wall thickness the cavity below would be mortared solid. You can see flashing below the weep hole so I wouldn't have any concerns about it. Photo 2 shows the flashing at the bottom of the brick so I don't know why they would have a brick shelf in some areas and not in others. Compare the top of foundation when viewed from the inside and see it it coincides with the location of the weep holes and flashing.
