Answer

Brief Explanations:

  1. For the first question: An improper mortar mix can lead to strength and adhesion issues. Cold temperatures can affect setting. Applying to damp bricks can cause bonding problems. Thin mortar joints can be weak. Antifreeze in mortar is often used to prevent freezing - related issues and is not a cause of mortar problems.
  2. For the second question: Weep holes are not only in solid masonry walls. They drain to the exterior to prevent water accumulation inside the wall. They are typically at the bottom of the wall. They often require flashing at the bottom to direct water out properly and are not a replacement for a vented rain - screen.

Answer:

  1. E. antifreeze in the mortar
  2. D. require a flashing at the bottom of the wall
