Concrete keeps Melbourne standing. It’s under the streets, behind the walls, and around every corner. From footpaths in Coburg to driveways in Doncaster, it holds up homes and runs through every job site. But what happens when you need to cut it?
Whether you’re renovating, building, or planning a new project, cutting through concrete is no small task. It takes the right tools, timing, and know-how. And if you’re just getting started, it can be hard to know where to begin.
This guide breaks it down. It covers the basics, tools, safety, and everything else you need to know about concrete cutting in Melbourne.
What Concrete Cutting Means—and Why It Matters
Concrete cutting is more than just slicing through slabs. It’s a precise process that clears the way for plumbing, cabling, expansion joints, and repairs. Without it, new work can’t move forward.
In Melbourne, concrete isn’t all the same. Some slabs are old and thick, some are full of steel, and others are light but brittle. Knowing what you’re cutting into matters as much as the tool you’re using.
Concrete cutting helps:
- Remove damaged areas without harming the rest
- Install pipes, wiring, or ducts
- Create expansion gaps in slabs or walls
- Trim or reshape surfaces to fit new plans
It’s not just useful. It’s essential. And if you’re starting out, knowing what new customers need to know about concrete cutting makes the job cleaner and safer.
Choosing the Right Tool for the Job
Different jobs need different tools. Get this wrong, and you might ruin the blade—or worse, damage the slab.
Here’s a quick look at the common types of cutting tools:
- Handheld saws: great for small or tight jobs
- Walk-behind saws: ideal for driveways, floors, and footpaths
- Core drills: perfect for making clean holes for pipes
- Wire saws: used for cutting thick concrete or odd shapes
Each tool works best with a certain blade and method. Dry cutting might suit outdoor work, but wet cutting keeps dust down indoors. In Melbourne, wet cutting is preferred because it meets safety and environmental rules.
Using the wrong saw or blade can cost you time, money, and safety. That’s why hiring someone with experience—or at least asking the right questions—can save you in the long run.

Knowing the Material You’re Dealing With
Concrete might look the same on the outside, but it isn’t. Some mixes are soft. Others have stone or steel mesh inside. Some slabs are layered over old materials, making the job harder.
Cutting old concrete in places like Brunswick or Richmond can be tough. These slabs often have thick rebar, crushed rock, or uneven thickness. Newer builds might use thinner, more uniform concrete.
Melbourne’s mix of old and new means you need to scan the concrete before you cut. A concrete scanner shows what’s inside—like pipes, mesh, or tension cables. This stops accidents and helps plan the best cutting method.
And remember, wet cutting keeps the dust down. It also cools the blade and makes for cleaner lines. For indoor jobs or tight spaces, it’s usually the safest bet.
Safety First: What Beginners Must Never Skip
Cutting concrete isn’t just noisy and dusty—it can be dangerous. Kickbacks, blade snaps, flying debris, and dust inhalation are real risks.
You need proper safety gear every time:
- Gloves and safety glasses
- A good dust mask or respirator
- Steel-capped boots
- Hearing protection
Before cutting, check your space. Make sure there’s no wiring, pipes, or weak spots. Mark your cuts clearly. Keep your gear in good shape. Always have a second person nearby for big jobs.
Melbourne also has strict rules about cutting dust and slurry. Wet cutting reduces airborne silica, which can damage your lungs. And cutting near storm drains or gardens needs care to stop runoff.

Keeping It Clean: Disposal Rules You Can’t Ignore
When you cut concrete, it doesn’t just disappear. Wet cutting makes slurry. Dry cutting makes fine dust. Both can be harmful to the environment if not handled right.
Melbourne’s EPA has clear rules:
- Don’t let slurry or dust go down drains
- Use trays, vacuums, or filters to collect waste
- Dispose of it at licensed collection points
If you don’t follow these rules, you can be fined. Or worse—have your job shut down. A cutting crew in Footscray once had to halt work after slurry leaked into a storm drain. Council stepped in, and the crew paid for cleanup and lost three days of work.
Plan for waste from the start. It’s not just clean-up—it’s smart business.
Real Example: Renovating a Café in Northcote
A small café in Northcote wanted to run new plumbing to the back kitchen. The owner hired a concrete cutter to trench through the old floor. But under the surface, the slab had reinforced mesh and moisture pockets.
The crew used a walk-behind wet saw, kept the area ventilated, and used a vacuum truck to catch all slurry. They scanned the floor first and adjusted their blade depth to avoid hitting old pipes. What could’ve taken days was done in six hours—no damage, no mess, no delays.
This shows how planning, the right tools, and clean work make a big difference.
Should You DIY or Call a Pro?
DIY can be tempting, especially with tool hire shops offering saws for the weekend. But unless you’ve done it before, it can go sideways fast.
DIY risks include:
- Damaging slabs or hidden pipes
- Blade snap or overheating
- Inhaling concrete dust
- Needing to redo the job properly
If it’s a simple garden path or shed slab, DIY might work. But for anything structural or deeper than 50mm, it’s safer (and often cheaper) to call in a pro.
Pros bring:
- The right saws and blades
- Safety and waste management
- Insurance and licenses
- Clean finishes that don’t need patching
Even for small jobs, they’re worth the cost.
Where Technology Is Taking Concrete Cutting
Concrete cutting isn’t stuck in the past. New gear is changing how jobs get done across Melbourne.
Look out for:
- Remote-operated saws for tight or high-risk areas
- Laser-guided cutting for better accuracy
- AI-based scanning to detect rebar and cables
- Eco-friendly blades that last longer and cut cleaner
Battery-powered saws are also gaining ground, making indoor jobs easier and quieter. With the push for greener construction, this tech is only getting better.
Expect concrete cutting in the future to be faster, cleaner, and even safer—especially as Melbourne grows and densifies.
FAQs: Answers to Common Concrete Cutting Questions
1) How much does concrete cutting cost in Melbourne?
Costs vary depending on the job size, location, and depth. A small residential cut might cost between $300–$600. Larger or reinforced jobs can range from $1,000 to $3,000 or more. Always ask for a full quote that includes disposal and clean-up. Prices also shift based on access and the type of saw used.
2) Can I cut concrete myself?
You can, but it’s risky. DIY cutting might be okay for small jobs like trimming pavers or cutting thin slabs. For anything deeper, reinforced, or near services, it’s safer to hire a pro. Without experience, you risk injury, property damage, or creating a bigger (and costlier) problem.
3) What’s the difference between wet and dry cutting?
Wet cutting uses water to cool the blade and control dust. It’s quieter, safer, and cleaner—great for indoor or urban sites. Dry cutting is faster but makes a lot of dust and heats up tools. In most of Melbourne, wet cutting is preferred due to safety laws and EPA regulations.
4) How long does it take to cut concrete?
Small cuts can be done in under an hour. Larger jobs, like trenching or cutting thick walls, might take a day or more. Timing depends on slab depth, rebar, access, and clean-up. Wet cutting can take longer because of water management and blade cooling.
5) Do I need council approval for cutting concrete?
Usually not for small, private jobs. But if you’re cutting near roads, footpaths, or public spaces, you may need permits or council approval. This applies to commercial or multi-res projects too. Always check before you start. Ignoring this can lead to fines or delays.
