The correct answer is D. All the above.
English garden wall bond is a type of brickwork bond that is used in the construction of garden walls. It is a very strong and durable bond that is able to withstand the elements. The bond consists of one course of headers to three or five courses of stretchers. This means that for every course of headers, there are three or five courses of stretchers. The headers are the bricks that are laid across the width of the wall, while the stretchers are the bricks that are laid lengthwise along the wall.
In each heading course, a queen closer is provided. A queen closer is a brick that is cut to half its length. It is used to fill in the space between the headers and the stretchers. This helps to create a strong and uniform bond.
The middle course of stretchers is started with a header to give proper vertical joints. This means that the first brick in the middle course is a header. This helps to ensure that the vertical joints between the courses of bricks are staggered. This helps to prevent the wall from cracking.
English garden wall bond is a very effective way to construct a strong and durable garden wall. It is a simple bond to learn and use, and it can be used to create a variety of different wall designs.
