Brick Bonds – Alternate courses of stretchers and headers What is the name of the brick bond in which the wall is constructed with alternate courses consisting entirely of stretchers and entirely of headers?

Introduction / Context:
Bonding patterns in brick masonry influence strength, appearance, and the distribution of joints. Two of the most common bonds are English and Flemish. Distinguishing them is a frequent exam topic because it affects coursing, quoins, and the need for closers.

Given Data / Assumptions:

• One course is entirely stretchers (bricks laid lengthwise along the wall).
• The next course is entirely headers (bricks laid with their ends showing).
• Courses alternate throughout the height.

Concept / Approach:

English bond is defined by alternate courses of headers and stretchers, producing a robust bond with good transverse strength. Flemish bond, in contrast, mixes headers and stretchers in the same course in alternating sequence. Pure stretcher or header bonds are single-type coursing used for partition thickness or facing and need backing to achieve transverse stability.

Step-by-Step Solution:

Verification / Alternative check:

Standard bonding diagrams and IS code illustrations show English bond as alternate header/stretcher courses, with queen closers at quoins.

Why Other Options Are Wrong:

Flemish mixes in-course; stretcher or header bonds are single-type courses; rat-trap bond uses cavity orientation and is distinct.

Common Pitfalls:

Forgetting to provide closers in English bond at corners; confusing visual patterns between elevations and plan bonding.

Final Answer:

English bond
