Breaking Concrete Isn’t as Simple as It Looks
Whether you’re tearing up a patio, removing an old walkway, or prepping a slab for trenching, using the right tool and approach matters. Demolishing concrete can quickly turn into a frustrating or even dangerous task if done incorrectly.
A project that could take two hours with the right tool and technique might stretch into an exhausting, full-day chore—especially if you're relying on a sledgehammer or the wrong type of electric demolition hammer.
Here are five of the most common mistakes people make when breaking up concrete—and how to avoid them.
1. Using the Wrong Tool for the Job
A common misstep is grabbing the first hammer available and hoping for the best. If you’re breaking up concrete in the backyard, a standard drill or rotary hammer simply won’t cut it. You’ll need the right size breaker.
For slabs thicker than four inches, an electric jackhammer is the best tool. The Tomahawk 1500W Electric Jackhammer, for example, offers 45 joules of impact energy—enough to break sidewalks, patios, and slabs without a compressor.
If you're wondering how to break up concrete without a sledgehammer, a proper demolition hammer or electric jackhammer is your safest, most effective alternative.
2. Skipping the Layout and Prep Stage
Demolition may feel like a “just go at it” kind of task, but failing to plan your work zone is a fast way to damage plumbing, rebar, or nearby surfaces. Before you start chipping concrete:
-
Identify the slab thickness
-
Locate any embedded pipes, wiring, or reinforcements
-
Mark boundaries for clean breaks
-
Set up barriers or plywood to protect adjacent structures
If you're using a jackhammer for patio removal or trenching, mapping out where to start and where to finish helps maintain a controlled working rhythm and avoids unnecessary patching later.
3. Ignoring the Importance of Bit Selection
Different tasks call for different chisels. Using the wrong bit can make your job harder and wear out your tool prematurely.
-
Use a pointed chisel for starting cracks in thick concrete
-
Use a flat chisel for widening breaks or lifting pieces
-
Use a wide scraper for removing tile adhesive or mortar
If you're removing floor tile over concrete or working on bathroom demolition, using a flat chisel with a demolition hammer will help you remove tile without damaging the subfloor.
4. Forgetting to Take Breaks (For You and the Tool)
Concrete work can wear you out, and it can also push your equipment to the limit. Even the best electric jack hammer for concrete needs rest periods. Electric models with thermal protection—like the Tomahawk—will shut off automatically if they overheat, but it's best to give the motor a break before that happens.
Your own safety matters too. Fatigue leads to accidents, poor control, and misdirected blows. Take short breaks to reset your stance, check your footing, and stay alert.
If you're unsure how to chip concrete safely, slow and steady wins the race. Let the tool do the work; don’t force it.
5. Underestimating Vibration and Noise Control
Concrete demolition is loud and jarring. It’s not just a comfort issue—it’s a safety concern. Not wearing hearing protection, gloves, and eye protection is a mistake that could cost you long after the job ends.
Electric jackhammers are quieter than pneumatic options, but they still generate enough decibels and vibration to require proper gear. And if you're planning indoor work like tile removal or concrete trenching, dust management and ventilation also become important.
For electric demolition hammer beginners, it's especially critical to wear anti-vibration gloves and maintain a two-handed grip for maximum control and reduced fatigue.
A Smarter Way to Tackle Concrete
Whether you're a weekend DIYer or a contractor prepping a site, knowing what not to do is just as valuable as knowing what to do. By avoiding these five common mistakes, you’ll work more efficiently, protect your tools, and get cleaner results—whether you're removing a patio, resurfacing a slab, or clearing space for new tile.
If you're in the market for a tool to handle these tasks, a mid-weight model like the Tomahawk 35 lb Electric Jackhammer delivers the power and versatility needed for residential and light commercial concrete removal.
