• A. 2 pounds per sq. yard
• B. 3 pounds per sq. yard
• C. 4 pounds per sq. yard
• D. 5 pounds per sq. yard

Answer: (B)

The minimum amount of damp-proofing required for foundation walls is set at 3 pounds per square yard. This standard is based on the need to protect foundation walls from moisture penetration, which can lead to structural issues and mold growth. The specified amount ensures that the damp-proofing material is applied adequately to provide an effective barrier against moisture from the soil. This requirement helps maintain the integrity of the foundation over time by preventing water infiltration, which can cause damage to the building structure. Ensuring compliance with this standard is crucial for the long-term durability and safety of residential construction in North Carolina.
