Blocklaying is a foundational aspect of construction, requiring precision and expertise to ensure the stability and durability of structures. This article outlines the key steps in blocklaying, drawing on the expertise of Bayview Brick & Block Laying, a trusted provider in Melbourne. We’ll cover everything from site preparation to finishing touches, helping you understand what’s involved in the process.
Site Preparation
Proper site preparation is crucial for successful blocklaying. It involves clearing the area of debris, ensuring the ground is level, and setting up a solid foundation. This step ensures that the blocks will be laid on a stable and even surface, reducing the risk of shifting or settling over time.
Laying the First Course
The first course of blocks is the most important, as it sets the foundation for the entire structure. Blocks must be laid carefully, ensuring they are level and properly aligned. Any mistakes at this stage can affect the stability and appearance of the finished wall. Tim from Bayview Brick & Block Laying says “spend plenty of time getting your layout correct. Ensuring your profiles and stringline are all correct is one of the most important steps to take before laying any blocks.”
Mixing Mortar
The mortar used in blocklaying acts as the glue that holds the blocks together. It’s important to get the right consistency for the mortar to ensure strong adhesion. A common mix for blocklaying mortar is the 6:1:1 ratio, 6 parts sand, 1 part cement, 1 part lime. Add water gradually to achieve a workable consistency. “If your mortar doesn’t stick to your trowel or blocks, add more lime. Different types of sand in Melbourne will produce stickier batches of mortar. You can use lime to adjust this” says the Bayview Brick & Block Laying team.
Laying Subsequent Courses
After the first course is set, subsequent courses are laid on top. This involves spreading mortar on the top of each block and carefully placing the next block, ensuring it’s level and aligned with the blocks below. Regular checks with a spirit level are essential to maintain the wall’s straightness and stability.
Cutting Blocks
In some cases, blocks may need to be cut to fit into corners or around openings. This requires precision to ensure that the blocks fit snugly without compromising the wall’s integrity. A masonry saw or chisel and hammer can be used for this purpose, depending on the required precision.
Joint Finishing
Once all the blocks are laid, the joints between them need to be finished. This step, known as jointing, involves smoothing out the mortar in the joints to create a clean, professional look. It also helps to seal the joints, making the wall more resistant to weather and wear. “When it’s hotter in Melbourne we have to joint faster to prevent the mortar from drying out” says Tim from Bayview Brick & Block Laying. “Make sure you don’t leave your mortar to dry for too long between courses”.
Curing
Curing is the process of allowing the mortar to set and harden. It’s essential not to rush this step, as proper curing ensures the long-term strength and durability of the wall. This process can take several days, depending on the weather conditions.
Final Inspection and Clean-Up
After the wall has cured, a final inspection is conducted to ensure there are no issues, such as cracks or misaligned blocks. The site is then cleaned up, removing any excess mortar or debris. This step ensures that the area is left tidy and that the wall is ready for use.
Key Takeaways
Blocklaying is a step-by-step process that requires attention to detail at every stage. From site preparation to the final inspection, each step plays a critical role in ensuring the stability and longevity of the structure.
By following these steps, and consulting professionals like Bayview Brick & Block Laying in Melbourne, you can achieve a high-quality finish that will stand the test of time.
