5. Explain the different types of bricklaying bonds.

• Stretcher Bond: Bricks laid in rows parallel to the wall face, providing a simple and durable pattern.
• Header Bond: Bricks laid with their short ends exposed on the wall face, creating a decorative appearance.
• Flemish Bond: Alternating rows of stretchers and headers, resulting in a classic and aesthetically pleasing pattern.
• English Bond: Similar to Flemish Bond, but with a running bond of stretchers in every third row between header rows.
• Stack Bond: Bricks laid vertically one above the other, creating a modern and minimalist look.

6. Describe the techniques for laying bricks in different patterns.

• Dry-Laying: Placing bricks without mortar, used for dry stone walls or as a preparatory step before setting with mortar.
• Butterflying: Spreading mortar on both sides of the brick for increased bond strength.
• Floating: Applying mortar only to the top of the brick, resulting in a flatter joint.
• Raking: Texturing the mortar joints using a tool to create different patterns and finishes.
• Tuckpointing: Repairing or repointing existing mortar joints to enhance durability and aesthetics.
