Our first blog on bricks last week discussed the different types of bricks that can be found and used within a structure, as well as the construction of a Cavity Wall… primarily, it was a blog on the basics! We suggest checking that out, here, before you carry on reading so you don’t miss out on any of the must-knows.
The different types of bricks used within a property could be somewhat described as step 1 when it comes to construction, step 2 being the topic of today’s blog, Bonding! Bonding refers to the pattern in which the bricks are laid. Primarily, this is a vital aspect of construction as the bonding pattern used is done so to ensure a strong and stable structure.
Before we get into it, let’s just clarify some key industry terms relating to the bricks themselves. The term ‘stretcher’ refers to the long, rectangle face of the brick, and the ‘header’ refers to the square face of the brick. There are a multitude of ways that the stretcher and header can be laid, all of which can affect the strength, stability, and aesthetics of a property. This means deciding on a preferred style of bonding at the beginning of construction is crucial.
Bonding Patterns
Header Bond
A popular type of bonding during the 18th century, the header bond pattern uses a substantial number of bricks and is usually reserved for high-quality buildings or otherwise radial brickwork, as the headers faces can accommodate smaller radii. The header bond pattern often utilises contrasting brick colours, to contribute to the aesthetics of the building.
Stretcher Bond
The stretcher bond involves courses being laid as stretchers with the joint of one course falling midway between the joints of the courses below. In modern construction, the outer leaf of a building envelope is only half a brick thick, stretcher bond has become the most popular these days. Especially because it is both cost effective and time effective.
English Bond
A traditional form of bonding, English brick bond alternates between both the stretcher and the header courses, with the headers being centred over the stretchers underneath. This was commonly used until the end of the 17th century, making it the oldest bonding pattern. It is a strong form of bonding, so continues to be used for structures such as bridges and embankments.
Flemish Bond
Traditional Flemish Bond includes alternate stretchers and headers on every course, with headers centred over the stretchers underneath. Flemish bond superseded English Bond from the beginning of the 18th century, although English Bond is often found to be stronger.
English Garden Wall Bond
A decorative form of bonding, the English Garden Wall Bond has 3 courses of stretchers between every course of headers, often in a different colour. Laying stretchers uses less bricks than laying headers, although this also makes it less strong, this is why it is used in modest structures such as traditional wall gardens.
Stack Bond
Whether it be vertical or horizontal, stack bonds do not have the bricks overlap. This is a typically weak form of bonding and is typically used as a decorative laying pattern with its striking effects.
Wild Bond
Suited to its name, wild bonding refers to when the bricks are laid in a somewhat random formation, delivering a cobbled and authentically traditional appearance.
Considering all the different variations of bonding, it is clear that bricks can be laid in a variety of ways, whether it be as soldiers (standing upright), stretchers (laid lengthwise) or headers (laid width wise).
So, what do we understand about brick bonding patterns?
They distribute lots of bricks throughout the structure to achieve maximum strength.
The bonding patterns is vital to ensure stability.
The bonding pattern is a key factor in creating the aesthetic of a building.
