Which bond is typically used when wire ties are employed in masonry construction?

• A. Header Bond
• B. Running Bond
• C. Stack Bond
• D. Herringbone Bond

Answer: (A)

Wire ties are used to lock together the inner and outer leaves of a cavity masonry wall, helping the two wythes act as a single unit and transfer loads evenly. For ties to work effectively, the bond pattern should offer regular, accessible points to pass and anchor those ties through the wall. A header bond provides this best because every brick is laid as a header, creating frequent crosswise units that ties can engage as they pass from one wythe to the other. This arrangement helps maintain alignment and enhances the wall’s stability by giving solid anchor points throughout the wall thickness. Other bonds orient bricks mainly along their long faces and through joints in ways that don’t offer as straightforward or reliable places to place and secure ties. Therefore, header bond is typically used when wire ties are employed.
