Concrete blocks help create a rugged structure. But sometimes, you need to resize them to ensure a proper fit where you need to lay them.
While this may seem like a daunting task, it isn’t always the case, especially if you’re equipped with the right tools. However, in some cases, the scope of your work may call for concrete cutting Melbourne services. Thus, it’s best to hire a professional.
Although you may use different tools to get the job done, a circular saw makes light work of cutting concrete blocks. Besides, it ensures an accurate and precise cut.
Plus, if you’re after a particular shape, you can move the saw around while cutting. Simply put, a circular saw is a fuss-free option for resizing concrete blocks. So, how do you use such as saw to cut concrete blocks the right way? Here’s how to go about it:
Tools You Need
- Circular saw with the proper blade- diamond-tipped blade or masonry blade (wet or dry)
- Safety glasses
- Dust mask
- Chalk line
- Cold chisel
- Tape measure
Wear your protective gear (items two to four above) before you get into the thick of things. Plus, ensure the blade is sharp and straight. Otherwise, you might be at risk of blade kickback, resulting in injury. Your work surface should also be clean.
1. Mark the Concrete Block
For a precise and accurate cut, be sure to mark off the section of the block you need to cut with a trusty chalk line. To mark a straight cutting path, it is best to use a tape- for measuring and marking.
Having a clear-cutting path ensures accuracy as you can easily follow the line as you make a cut with the circular saw. Otherwise, you may not get the job done right if you jump headlong into it. Besides, you’re likely to ruin your blocks.
2. Adjust Your Saw
Select the appropriate blade for the cutting job. While blade measurements vary, you can quickly determine the right blade by checking the thickness of your concrete block.
A circular saw is ideal for cutting blocks 15cms thick at most. To do this effectively, the blade depth needs to be roughly 50mm. Otherwise, you’d have your work cut out. Adjust your circular saw to ensure it properly aligns with the line you marked in step one.
While at it, keep the blade firm and straight. It’s also advisable to hold the saw still and not start cutting until it attains its maximum rotation. Doing so allows you to make a firm, clean cut on the block, which would guarantee the best results.
3. Start Cutting
Hold your circular saw with both hands and position it on the marked line. Since the saw exerts pressure, be sure to keep holding it tightly. Otherwise, it may fall back if you fail to maintain a steady grip.
Start cutting by moving the saw slowly over the drawn line. Cut around the block- the idea is to create an impression on the block, which you can follow to make a deeper subsequent cut. Avoid forcing the blade. Let the saw do its thing as you guide it slowly.
Take breaks after cutting for 45 seconds to allow the blade to cool. When dry-cutting, allow the blade to run free for a while to clear out debris- you may also run the blade with or without water.
Pausing for a moment also prevents dust build-up. And if you’re using a wet blade, you may have to rope in someone to sprinkle some water on the blade as you proceed.
4. Finalize Cutting
Keep cutting, and remember not to force the saw over the block. Otherwise, you risk ruining your concrete block. Turn off your circular saw if you need to make a deeper cut. Then, adjust the blade depth by making small increments to the desired depth. Then, you may proceed with your work.
Once you’ve cut both sides of your block, use a chisel and hammer to split it into two. Apply moderate force, as applying too much pressure may cause unintended block breakage.
Create a clean edge by tapping away bits and pieces of concrete left behind with your chisel and hammer.
If the block is thicker than 15cm, you may have to use a sledgehammer for the final split after cutting the concrete block. Hammer as close as possible to the cut, but not on it. Be careful as you strike the block, as broken pieces can fall back and lead to injury.
Ultimately, by wearing the right gear and using the right tools, you can cut concrete blocks easily and safely. By following the steps we’ve outlined, you’ll be on your way to making precise cuts and doing it the right way.
