flashing brick

is flashing supposed to have a bed of mortar in it where the weepholes are placed? I know some mortar will fall ino the flashing but I have seen where it looks like the mortar was filled in to the flashing intentionally.

For veneer and a cavity wall, the space between the brick and the back-up (wood or concrete block) should be open to permit water to run laterally and drain out of the weep holes.

There are materials designed to prevent mortar, and construction debris from clogging up the drainage path to the weep holes. Unfortunately, you normally find this in commercial construction.

Normally, a small amount of blockage is not a problem since the amount of moisture is low and there is no pressure differential (from wind or others) between the gap and the exterior. The water will find a way out if the gap in not filled with solid, packed mortar. Since mortar is relatively dry, the droppings are not very dense or compacted.

To answer your question, the mortar should not be filled into the gap intentionally. It serves no purpose.
