Why do Some UK Bricks have Holes?
Most standard clay facing bricks are solid throughout. Generally speaking, their rectangular shape and dimensions are stable and smooth.
Having said that, you may have come across some clay bricks with holes. These holes, usually in a row of three, sit on the top surface, running lengthways.
What's the purpose of these facing bricks that contain holes? Why are they there, and what purpose do they serve? Are these bricks superior to standard smooth bricks with the same dimensions? Modular Clay Products are here to clear up any misconceptions and confusion.
Why do Bricks Have Holes in Them?
It's useful to understand why some bricks have holes, as these unique products may affect any commercial structure they're expected to uphold.
Some bricks have holes for several reasons, with the most important including:
Weight Reduction
They weigh considerably less than their consistently smooth counterparts, making them easier to handle during construction.
Cost-Effective Manufacturing
Perforated bricks serve as a cost-effective alternative to solid clay bricks, benefiting both manufacturers and customers.
Material Conservation
Manufacturers can save on raw materials, as brick holes require less clay per unit produced.
Efficient Firing Process
The holes allow consistent and faster heat distribution when bricks are being fired in kilns, resulting in even and thorough curing throughout the material.
Enhanced Mortar Bonding
Perhaps most importantly, the perforations enable brick mortar to seep through and connect to adjacent bricks more effectively.
This final point is particularly important. The holes allow the masonry brickwork to be constructed with an added level of security. Bricks are turned when used in construction, so the holes remain concealed within exterior wall structures. When filled with mortar, these cavities provide a system of locking bricks closer to one another, creating a more cohesive and stable build.
Why are Bricks with Holes Useful?
There are numerous benefits of bricks, not least their incredible durability, strength and load-bearing capabilities. Bricks with holes only enhance and give credence to their immense physical properties, not to mention their aesthetic value and versatility.
Structural Advantages
By incorporating holes in bricks, there is additional space to connect each brick to one another with mortar and rebar. This ensures extra structural stability within the exterior walls of commercial buildings, creating a more robust and dependable framework.
Logistics and Transportation Benefits
Given that these perforated bricks are lighter than standard facing bricks, brick suppliers such as Modular Clay Products can transport larger quantities more efficiently. This helps us deliver more bricks to our clients with each order, whilst saving on time and reducing the number of deliveries required.
Manufacturing Efficiency
Placing holes in the bricks' centres benefits the manufacturer as much as it does the supplier. When the brick manufacturing process commences, the clay extraction and formation require considerable effort. By leaving holes, residual clay is then conserved for future bricks, thus aiding in material conservation and environmental sustainability.
The firing process is improved in terms of time efficiency and effectiveness, as the holes allow for quick penetration of heat throughout the material. When fired, the heat engulfs the bricks more rapidly, saving on fuel costs whilst ensuring a thorough and even cure.
Brick Clay Pavers
Brick clay pavers are directly applied to flat surfaces after being refined, smoothed and treated with sand, which collectively forms a durable surface area capable of withstanding large amounts of weight and pressure.
Without holes, solid bricks remain entirely suitable for projects involving:
- Retaining walls and boundary structures
- Roads and driveways
- Patios and courtyards
- Pavements and pathways
- Steps and terracing
Common Misconceptions About Perforated Bricks
Despite their widespread use in the construction industry, several myths persist about bricks with holes. Some people mistakenly believe that perforated bricks are inferior or less durable than solid bricks, but this couldn't be further from the truth. When properly installed and used in appropriate applications, holed bricks offer equivalent or even superior performance compared to their solid counterparts.
Another common misconception is that the holes weaken the brick's structural integrity. In reality, when these bricks are laid correctly with the holes facing upwards and subsequently filled with mortar, they create an interlocking network that actually strengthens the overall structure. The mortar penetrates through the perforations, forming vertical columns of bonding material that tie multiple courses together more effectively than surface bonding alone could achieve.
Safety and Quality Considerations
When using any clay brick product, the priority should always be its safety and reliability. If bricks have damaged or compromised holes, it would be unwise to use them as they may jeopardise the building's structural stability.
When building with high-quality bricks, a systematic approach should be followed. The appropriate bonding pattern needs to be considered, as do the materials' sustainability credentials and how the bricks can withstand various weather conditions. Proper installation techniques ensure that brick holes serve their intended purpose – creating stronger, more durable structures that stand the test of time.
Understanding the purpose of brick holes helps architects, builders and construction professionals make informed decisions about which products best suit their specific project requirements. Whether you opt for perforated or solid bricks, choosing quality materials from reputable suppliers like Modular Clay Products ensures your construction projects are built to last.
Brick Selector
Modular Clay Products’ brick selector tool is an easy-to-use tool where you can browse our massive range of bricks, with or without holes. Although there is no option to view bricks with or without holes exclusively, you can still choose bricks by colour, variation and texture, or a mixture of all three.
By being as specific as possible, you can save so much time browsing our full range and have a smaller range of particular products to choose from. For example, you can select options to view all of our blue glazed bricks or grey wirecut bricks, and find ones with holes in these ranges much more easily and quickly.
