Answer

Brief Explanations:

  1. For the first question about masonry walls: Masonry walls can be load - bearing or non - load bearing, they usually need a foundation, abrasive cleaning can damage them. While they are not inherently water - repellent and can be installed at or below grade with proper precautions.
  2. For the second question about exterior cladding problems: Water penetration, being too close to grade, window openings, roof surfaces, and planters against the wall can all cause issues. But being too close to window openings is not a common problem for all exterior cladding in a general sense compared to the others.

Answer:

  1. they are water repellent
  2. too close to window openings
