It may sound obvious, but cutting concrete is no easy task – no matter how you do it or what concrete cutting techniques are used. First, it’s a tough and physically demanding job, but it’s obviously also extremely dangerous if you don’t know what you’re doing. In fact, there are strict safety regulations across Victoria and Australia that restrict certain types of concrete cutting to licensed professionals – ensuring both the safety of the operator and the integrity of the job.
However, some confident and savvy DIY enthusiasts may be tempted to tackle certain manageable projects on their own – whether it’s to save money, gain hands-on experience, or simply for the satisfaction of completing a challenging task themselves.
But be warned!: This isn’t something you can jump into without serious consideration.
Why DIY concrete cutting isn’t just a matter of ‘Getting Stuck In’
To you, amateur concrete cutting may seem like a straightforward way to save on labour costs, but it’s far from a simple task. Before even dreaming of cutting into that slab, there are numerous factors to consider.
For one, different concrete cutting techniques apply to different jobs – and choosing the wrong one could lead to damage, expensive mistakes, or even severe injuries. You’ll also need the right tools, such as specialised saws and blades, to match the material and project size. And let’s never forget about concrete cutting safety, because improper handling can result in concrete fragments flying, inhalation of harmful dust, or worse, causing an accident that could even be fatal.
Concrete cutting involves using specialised equipment like diamond blades, which are much more complex than your average saw. It’s also essential to know how different cutting techniques interact with the material. There are many more than one standard concrete cutting method, and it’s crucial to match the method to the task. Getting this wrong could leave you with cracked concrete, damaged equipment, or a horrific injury. So let’s proceed with caution!:
DIY or professional? Getting the job done right!
If the risks haven’t scared you off yet, it might just be possible to get concrete cutting done correctly – if you take the time to learn how to choose the right method. Whether you’re cutting through a concrete slab, a driveway, or a structural wall, understanding the various methods and tools available will determine your success.
But let’s not forget that licensed professionals bring in years of experience, advanced concrete cutting knowledge, and have access to high-grade tools and safety protocols that are out of reach for most DIYers.
Still keen to give it a go? Or do you just want to know? Well, here’s a full breakdown of the most common simple concrete cutting methods, how to tackle them yourself, and how a professional would handle the same task:
1. Hand saw cutting
DIY: How To Cut Concrete Without A Saw
If you’re attempting to cut a small slab of concrete and don’t have access to specialised equipment, you might try using a hammer and cold chisel to score and break the concrete.
While this might work on very thin sections, it’s a time-consuming process and not suitable for anything thicker than 50mm or so. The main risk? Uneven cuts and shattered pieces.
Professional: They’d use a hand saw fitted with a diamond blade, ensuring precision and clean lines. This is a fast, controlled technique suited to small areas like slabs or blocks, and pros can handle even thicker sections very safely.
2. Wall sawing
DIY: Concrete Wall Cutting
Cutting through concrete walls is where things get trickier – especially for the amateur. While you could rent a wall saw, this is a specialised and dangerous tool that requires experience to operate safely. Getting it wrong here could compromise structural integrity.
Professional: Pros use hydraulic or electric wall saws, often with remote controls, ensuring both accuracy and safety. This method is ideal for creating openings in walls for doors, windows, or ventilation systems, and it’s not something you want to tackle without proper training.
3. Wet cutting
DIY: How To Cut Concrete With Water
Wet cutting involves using water to reduce dust and cool down the blade, and is ideal for larger outdoor projects like driveways. If you’re attempting this as a DIY project, you’ll need to rent a wet saw and ensure you have proper water management in place to avoid creating a mess or dangerous worksite.
Professional: For professionals, wet cutting is second nature. They use the right balance of water pressure, blade speed, and cutting angle to get the job done efficiently without risking blade damage or uneven cuts. They also have the equipment needed to manage water runoff effectively.
4. Floor sawing
DIY: How To Cut Floors Accurately
Floor sawing requires a large, walk-behind saw, which can be rented. However, these machines are heavy and difficult to control, making it hard to achieve straight cuts without experience. There’s also the added risk of damaging any underlying utilities.
Professional: Professionals will quickly and safely cut floors to precise measurements, using specialised equipment like walk-behind saws with diamond blades. They have the expertise to avoid utilities, get accurate depth control, and complete the task in a fraction of the time.
5. Core drilling
DIY: How To Drill Holes In Concrete
Core drilling is used for making holes in concrete, such as when running pipes or wiring. While smaller core drills are available for rental, they can be tricky to use and often result in messy, imprecise holes.
Professional: Professionals use powerful core drills with diamond bits, making clean, precise holes in walls or slabs without damaging the surrounding material. This is essential for structural integrity and reducing the risk of cracks or breaks.
Why professional help is usually the wise choice
While it’s tempting to try a DIY approach to concrete cutting, the risks often outweigh the rewards. With so many different concrete cutting techniques available – more than appear in our list, anyway – it’s easy to get overwhelmed. From choosing the right tools and basic concrete cutting techniques to ensuring the job is done safely, professionals have the experience, equipment and confidence to get it right the first time every time. And the cost of getting it wrong? Expensive repairs, wasted time, and the potential for regulatory trouble or – worst of all – serious injury.
