Which block type is commonly used as the top course to cap a masonry wall?

• A. Cap Block
• B. Bond Block
• C. Pilasters
• D. Channel Block

Answer: (A)

Cap block is used as the top course to cap a masonry wall. It’s designed to finish the wall with a flat, uniform edge and to help shed water away from the surface, protecting the wall from weather. The top block sits on the uppermost layer and provides a clean face that can be pointed or receive coping material for a durable finish. Other block types serve different roles: bond blocks contribute to the wall’s bond pattern, pilasters are vertical elements for support or decoration, and channel blocks have channels for reinforcement or drainage, not for finishing the top edge.
