Humber/Ontario Real Estate Course 2 Exam Practice

When constructing a residential brick veneer wall, which of the following is a correct structural detail?

1. All rows of bricks must be oriented endwise to ensure wall stability

2. An air gap should be left between the brick and sheathing layer

3. There is no requirement for weep holes in brick veneer walls

4. The brick veneer transfers the loads directly to the foundation

5. Bricks should be laid horizontally without gaps for better support

6. Bricks must be reinforced with metal ties to maintain integrity

The correct answer is: An air gap should be left between the brick and sheathing layer

When constructing a residential brick veneer wall, it is essential to leave an air gap between the brick and the sheathing layer. This air gap allows for moisture that penetrates the brick veneer to drain down and exit the wall system, helping to prevent moisture buildup and potential damage. This detail is critical for the proper functioning and longevity of the wall system. The other options are not correct for various reasons: - Option A is incorrect because not all rows of bricks need to be oriented endwise for wall stability. Brick veneer walls can be adequately constructed with the bricks laid in the standard horizontal orientation. - Option C is incorrect as weep holes are actually a necessary component of brick veneer walls to allow for drainage of any water that may get behind the brick. - Option D is incorrect because the brick veneer is not meant to transfer loads directly to the foundation; rather, it is a non-structural component that sits in front of the structural wall. - Option E is incorrect as leaving gaps between bricks and using appropriate mortar is important for accommodating movement and ensuring stability. - Option F is incorrect because while metal ties may be used in some instances to provide additional support, they are not a universal requirement for all brick veneer walls.
