There is mortar or caulk in the lines between bricks and concrete blocks. If the surface of the masonry isn’t covered, these lines make a big difference in how the construction looks.

A brick structure has different types of lines, each with an individual name and characteristics. This article explains each line of the brick structure in detail.

What is the line Between Bricks called?

The lines between bricks and concrete blocks are filled with mortar and are called mortar joints. Different mortar joint designs not only make the building look a bit different but also ensure it doesn’t leak and keep the structure strong.

Types of Brick Mortar joints

Bed joints are the horizontal lines between brick layers. They are the lines filled with the mortar in the brick structure that looks like the bedding.

Head joint

The vertical lines filled with mortar between each brick or concrete block are called head joints.

Collar joint

When two bricks are joined together to make the wall thicker than the thickness of one brick, the joint between the “wythes” is called a “collar joint.

V Joint

This type of joint can be made right after the bricks are laid with a V-shaped jointer or a spade. The joint is decorative and easy to see. It hides small flaws and is very attractive.

Flush Joint

A flush joint is a joint in brick or stone where the mortar is finished so that it is flush with the surface.

Extruded Joints

If there is too much mortar in the joint, an extruded joint will naturally squeeze out and make a gap between the bricks.

Struck Joint

It is a joint where the bottom of the mortar is straightened with a trowel while the mortar is still not hardened.
