Coastal and Floodplain Construction Inspector's Practice Exam

What is required regarding masonry in accordance with the Home Builder's Guide?

1. All masonry cells must be filled

2. Some masonry cells should be filled

3. Masonry must be coated with waterproof paint

4. Only exterior masonry cells need to be filled

The correct answer is: All masonry cells must be filled

The requirement that all masonry cells must be filled is based on structural integrity and moisture control principles outlined in the Home Builder's Guide. Masonry walls are often designed to be load-bearing and contribute to the stability of the structure. When all cells in a masonry unit are filled, it enhances the wall's strength and resistance to lateral forces, such as wind and seismic activity. Moreover, filling all cells helps to prevent water intrusion and manage moisture effectively, which is crucial in coastal and floodplain areas where exposure to water is a concern. This practice mitigates the risk of damage from freeze-thaw cycles and also supports the overall durability and performance of the masonry. The other options do not meet the standards set by the Home Builder's Guide because they suggest partial filling or additional treatments that may not adequately address the structural and moisture-related issues associated with incomplete filling of masonry cells. In high-risk areas, thoroughness in masonry filling plays a critical role in safeguarding the building against environmental stresses.
