We handle everything from delicate residential patios that require hand-breaking near prize-winning gardens, to massive industrial floor slabs that need hydraulic excavators and specialized crushing equipment.
What Sets Professional Slab Removal Apart
The difference between amateur slab removal and professional work shows up in three places: the safety protocols that protect your property and everyone around it, the precision that preserves utilities and adjacent structures, and the site preparation that sets up your reconstruction project for success. When you’re investing in major renovation or new construction, that foundation matters more than most people realize.
Our Slab Demolition Services
Residential Slab Demolition
We handle all types of residential slab removals, from basic house foundations and garage floors to patios, basements, pools, and workshops. Each project is approached with care to protect surrounding structures, utilities, and landscaping. Whether it’s a small outdoor slab or a complete house foundation, we adapt our methods to suit site conditions, timelines, and safety requirements.
Commercial Slab Demolition
Commercial projects demand precision and coordination. We’ve completed office, retail, restaurant, medical, and school slab removals while minimizing disruption to operations. For heavy-duty jobs like warehouses, industrial floors, or multi-story buildings, we bring in advanced equipment and work closely with engineers and property managers to ensure structural integrity, safety, and compliance.
Specialized Slab Demolition
Some slabs require advanced techniques and expertise. We manage reinforced, thick, and post-tensioned slab removals with specialized cutting and engineering oversight. Contaminated slabs are handled with strict environmental compliance, while heritage and underground structures demand careful preservation and excavation. Large-scale projects like bridge decks and infrastructure removals involve civil coordination, traffic control, and utility protection.
Advanced Slab Demolition Techniques
Heavy-Duty Demolition Equipment
We use a full range of specialized equipment, from compact excavators for small residential slabs to 30-tonne machines for thick industrial concrete. Concrete pulverizers, diamond blade saws, jackhammers, and demolition shears allow us to break, cut, and remove slabs with precision while protecting nearby structures. Skid steers handle debris removal, and advanced dust suppression systems ensure safety and environmental compliance.
Precision Slab Removal Techniques
Our methods focus on control and efficiency. Controlled sectioning minimizes vibrations, while reinforcement cutting uses advanced locating tools to prevent damage. Utility coordination ensures embedded systems are protected, and sequential removal maintains safety and workflow. Access optimization allows us to adapt to tight spaces or complex sites with minimal disruption.
Safety and Environmental Protection
We prioritize safety with constant monitoring, comprehensive insurance, and strict site protocols. Utilities are carefully located and protected, while dust, debris, and noise are controlled with professional suppression systems. We also ensure full environmental compliance when handling contaminated materials and maintain secure, well-managed worksites at all times.
Why Choose Professional Slab Demolition
Safety and Structural Expertise
Professional slab demolition ensures your property is protected from costly mistakes like cracked foundations or severed utilities. Licensed contractors assess slab thickness, reinforcement, and hidden systems using advanced tools like ground-penetrating radar before work begins. Crews follow strict safety protocols, are trained for hazardous situations, and carry comprehensive insurance to cover your property and neighboring structures. Coordination with structural engineers, emergency preparedness, and quality control guarantee safe, precise removal without damaging adjacent areas.
Professional Equipment and Efficiency
Specialized demolition equipment allows professionals to remove slabs in hours instead of days, using advanced cutting and breaking techniques that minimize disruption and reduce costs. With expert sequencing, debris management, and continuous truck loading, projects run smoothly and efficiently. Professional project management also ensures your site is ready for reconstruction on time, with no costly delays or hidden surprises.
Environmental Responsibility and Site Preparation
Every project is handled with environmental responsibility in mind. Concrete is recycled through certified facilities, reducing landfill waste and disposal costs. Professionals go beyond removal by grading and preparing the soil for future construction, landscaping, or development. Contaminated materials are disposed of safely, site restoration meets reconstruction standards, and full documentation of recycling and compliance is provided. This ensures your project is not only efficient but also environmentally sound and future-ready.
Our Professional Slab Demolition Process
Pre-Demolition Assessment and Planning: Every project begins with a detailed slab evaluation, using ground-penetrating radar and core drilling to assess thickness, reinforcement, and hidden systems. We coordinate with utility providers to prevent costly damage, consult structural engineers for complex slabs, and plan equipment use based on site conditions.
Site Preparation and Safety Setup: Before demolition begins, we secure the site with barriers, access control, and safety zones. Utilities are disconnected and protected, while dust suppression and air filtration systems are installed to maintain air quality.
Slab Demolition and Removal: Demolition follows a systematic plan, breaking slabs in controlled sections to avoid unexpected fractures. Reinforcement cutting and embedded system removal are handled with specialized equipment, while continuous monitoring ensures quality and safety.
Site Cleanup and Reconstruction Preparation: After removal, all debris is cleared and disposed of or recycled according to environmental standards. The site is graded, compacted, and prepared for reconstruction, creating optimal foundation conditions. Final inspections confirm complete removal and site readiness, with documentation provided for compliance and records.

Frequently Asked Questions About Slab Demolition
How long does it take for a concrete slab to harden?
In Canberra’s climate, concrete typically reaches initial set in 2-4 hours, but full hardening is a much longer process. With our temperature swings from -2°C to 42°C, I’ve learned that concrete behavior changes dramatically with the seasons.
Summer pours can reach walking strength in 6-8 hours, but winter pours might take 12-16 hours before they’re safe to walk on. The reactive clay soils around places like Forrest and Red Hill mean we need that concrete to reach proper strength before any load-bearing. I always recommend waiting 7 days before any serious weight, and 28 days for full structural strength.
How long to wait to cut a concrete slab?
This is where experience with Canberra’s conditions really matters. Generally, I start cutting 4-6 hours after the pour when the concrete is firm but not fully hard. Too early and you get aggregate pullout, too late and you risk random cracking.
In summer, that window might be just 3-4 hours because of how fast concrete sets in the heat. Winter gives you more time – sometimes 8-10 hours. The trick is doing the “footprint test” – if you can walk on it without leaving deep impressions, it’s usually ready for cutting.
For those big commercial slabs we do in Civic, timing is critical because the building schedule doesn’t wait for perfect weather.
How long to leave a slab before building?
In Canberra’s climate, I recommend waiting at least 7 days before starting any serious construction on a new slab. That gives the concrete time to reach about 80% of its final strength and handle construction loads safely.
But here’s where local knowledge matters – if we’ve had a wet winter like last year, and you’re building on reactive clay soils, I’d actually recommend waiting 14 days. The soil movement from moisture changes can stress a slab that hasn’t fully cured.
For those big commercial developments in Civic or Barton, developers are always pushing for faster timelines, but rushing this stage just leads to problems later.
Should you pour a concrete slab before or after a shed?
This is a great question I get from DIY homeowners in the outer suburbs. Generally, I recommend pouring the slab first, especially in Canberra where our soil conditions can be tricky.
Pouring first gives you better access for equipment and ensures proper compaction around the edges. Plus, with our reactive clay soils, you want that slab properly cured and settled before adding the structure weight.
The exception might be in windy areas like some parts of Gungahlin, where you might want the shed frame to protect the concrete during curing.
Do you need training to use a jackhammer?
Absolutely. Jackhammers are powerful tools that can cause serious injury if used incorrectly. Plus, there are techniques for efficient breaking that only come with experience.
Most of our crew members have formal training in equipment operation and workplace safety. It’s not just about safety – proper technique prevents fatigue and gets better results.
For DIY homeowners, I always recommend starting with smaller electric units and working on practice areas before tackling the main project.
