1. Terms are Used in Masonry Works
The terms which are in common use in masonry have been defined below:-
It is full brick or stone which is laid with its length perpendicular to the face of the wall. Thus a brick laid as header will show its face measuring 10 cm × 10 cm. (in case of modular) on the face of wall. In stone masonry, header is sometimes termed as through stone.
It is a full brick or stone which is laid with its length parallel to the face of the wall. Thus a brick laid as stretcher will show its face measuring 10 cm × 20 cm (in case of modular brick) on the face of the wall.
It is a term applied to the overlapping of bricks or stones in a wall in alternate courses, to bind the whole wall together. Bonding is essential to eliminate continuous vertical joints both in the body as well as on the face of the wall.
A horizontal layer of bricks or stones is termed as a course. Thus in brick masonry with modular bricks the thickness of a course will generally be equal to 10 cm. plus thickness of one mortar joint.
- Header course
It is a course of brick work entirely composed of headers.
- Stretchers Course
It is a course of brick work in which all the bricks are laid as stretchers.
It is a term used to indicate the lower surface of the bricks or stones in each course. It may also be termed as the surface of bricks on which it rests.
The surface of a wall exposed to weather is termed as face.
The material used in the face of the wall is known as facing.
