c) Raking
What is Raking bond?
Raking bond is a type of bonding where bricks are set at an angle to the face of the wall. This technique is used when the bricks are arranged diagonally, rather than horizontally or vertically. Raking bond is unsuitable for walls of thickness less than 1.5 bricks because the diagonal orientation of the bricks requires a larger thickness to maintain structural integrity. When used in thinner walls, raking bond can lead to instability and weakness in the construction.
Raking bond is commonly employed for walls that are thicker than one and a half bricks to ensure stability and strength. The angle at which the bricks are set in a raking bond can vary, but it is typically between 45 to 60 degrees from the horizontal. This arrangement creates a visually appealing pattern on the surface of the wall while also providing additional strength to the structure.
In conclusion, raking bond is a bonding technique that is unsuitable for walls of thickness less than 1.5 bricks due to the structural challenges it presents. It is important to choose the appropriate bonding type based on the thickness of the wall to ensure the durability and stability of the construction.
