This arrangement helps to increase the longitudinal stability of thick walls built in English bond. The mortar should not be pressed in too hard. This brick bond was commonly used on grand structures and Government buildings. What are the Different Brick Sizes? After being drawn from the machine the filled moulds are emptied by hand and the bricks taken to the dry shed.
Types of Brick Bonds
The bricks were then stamped with the mark of the legion who supervised the brick production. Alternate courses of headers and stretchers like English Bond but with the joints aligned with the centres of the bricks in alternating stretcher courses. Early civilisations around the Mediterranean adopted the use of fired bricks, including the Ancient Greeks and Romans. We have an old mysterious foundation here, speed dating events in springfield which seems to be mortared entirely with modern cement.

Over the years different bonds emerged, driven by considerations of strength, cost, ease of laying and fashion. However there are some bricks which are more porous and therefore more susceptible to dampness when exposed to water. In grand houses, sometimes the bricks were larger. Brick and terracotta architecture is dominant within its field and a great industry has developed and invested in the manufacture of many different types of bricks of all shapes and colours.
The Construction Civil
It was used for small structures that didn't need to support much weight like the tops of chimneys from the earliest times. Rather than being made with clay they are made with lime binding the silicate material. These are extensively used in some regions. For small structures and small additions to buildings which do not support much weight, like pents, and mom running bond was often used.
For conclusive dating, we must always use several methods in combination for the most accurate results. These details can provide additional clues for dating a building by the brickwork. One difficulty with using brick bonds for dating historic buildings is that each different bond was used for a relatively long time. English bonds are very durable because the brick joints are unlikely to overlap. This is continuous conveyor belt with bricks being dried and added at one end while at the other end they are being burnt.
The stretchers above and below this row are staggered to prevent the joints from lining up. Rat Trap Bond painted over Wokingham. Blocks made of terra-cotta are light and durable. It was a common practice for foundations to be laid in English bond and for the facade above the water table to be laid in Flemish bond. This bond is not traditionally used for structural walls but has been used in non-structural applications for centuries as well as for structures where a great deal of strength is not required.
Another potential problem with this system is that many buildings have been repaired or added onto over time. Dry pressed bricks however are now commonly used for face bricks. On accounts of its good appearance, this bond is sometimes used for the construction of the outer leaves of cavity walls. The buildings around this time were mainly built from fired red clay bricks.
What Are the Different Types of Brick Bonds
- If there is a large proportion of sand used in the mixture the brick will be more textured and shapely.
- The finished blocks are cured, rather than fired, using low-pressure steam.
- Attachments can also be added to the die which gives the brick its texture from brush, roll, and scratch to roughen.
- In operation, new green bricks, along with roofing bricks, are stacked at one end of the brick pile.
Stretchers are bricks which are laid parallel to the face of a wall. Production of bricks increased massively with the onset of the Industrial Revolution and the rise in factory building in England. Flemish Bond This bond has alternating headers and stretchers along each course. Lightweight bricks also called lightweight blocks are made from expanded clay aggregate. Again not something you would likely have to worry about with a farm house.

He also had to know when to quench the kiln with water so as to produce the surface glaze. We can match mortar colours perfectly and permanently and all work is guaranteed for the life of the brickwork. Building bricks are a mixture of clay and sand which is mixed with water to create the correct consistency. Strength is less critical for end walls, which are normally plain, than for front and rear walls with many door and window openings. It is these impurities which when burned in a kiln create the calcium silicates or aluminates that react with water to set.
The colour and place of manufacture is reflected in the brick names. Blocks have a much greater range of sizes. The differences in brickwork through history are marked and easily distinguished. Cherry is used as a term when the clay which has been used burns red.
Types of Brick Bonds
In other cases in such grand structures, bricks were glazed, or rubbed, for decorative effect and gauged cut to go around openings. Different types of brick bonds are determined based on which side of the brick is positioned towards the outside of the structure, as well as how the bricks are placed in relation to one another. It was the ability to spot different bonds while walking around a town that first got me interested in brickwork. This article is about the building material.
- By using a combination of headers and stretchers a wall not only gains strength but also the possibility of decorative patterns arises.
- When made with adequate amount of cement they are suitable for harsh environments such as wet conditions and retaining walls.
- However a clay which burns to a red colour will provide a stronger brick than clay which burns to a white or yellow brick.
- Joints are not staggered between courses.
- For example, a brick placed so that its large face is parallel to the ground, and its longest side facing out is known as a stretcher.
The overlap, which is usually of half brick, is obtained by commencing each alternate course with a half brick bat. In this case, the brick work and other evidence corroborates the written accounts we have found giving approximate dates for the structure. Engineering Bricks Engineering bricks are called so due to their overall strength and water absorption. Three basic types of brick are un-fired, fired, and chemically set bricks. Rat Trap Bond showing cavity Wokingham.
Structural walls require some type of structural bond, while decorative walls may use any bond pattern. An independent style of brick architecture, known as brick Gothic similar to Gothic architecture flourished in places that lacked indigenous sources of rocks. It is entirely possible that a crumbling foundation was repaired, rebuilt, or covered at some point in the life of a building using the current methods.
Look up bricks in Wiktionary, the free dictionary. For under water construction Portland cement mortars should be used. Flemish brick bonds date back to the Tudor period in England, when masons were looking for a more attractive alternative to traditional English bonds. The alternative headers should be centred over and under the vertical joints.
This bond is the most commonly used today. In especially grand Flemish bond structures headers were glazed for contrast. The names of bricks may reflect their origin and colour, such as London stock brick and Cambridgeshire White. It applies to both brick walls and brick paving for patios and paths, top us as well as to concrete block and other types of masonry construction.
Common Types of Brick Bonds Used in Masonry
Enlgish bond consists of alternating courses of headers and stretchers. Depending on the country, either the extruded or soft mud method is the most common, since they are the most economical. They are usable across this range as they are lighter than clay bricks. After this process the bricks are then transferred to the kiln for burning. Two basic categories of bricks are fired and non-fired bricks.
