Concrete Demolition Cost

Removing old concrete is often the first step in many renovation or construction projects. Whether you're replacing a cracked driveway, removing a patio, or preparing for new landscaping, understanding the concrete demolition cost helps you plan and budget effectively. In this guide, we explore typical pricing, key factors that influence costs, DIY versus professional options, and ways to reduce the total cost.

Average concrete removal cost in Australia

For most homeowners, concrete removal costs typically range from $2 to $6 per square foot, or $50 to $120 per square metre. The average cost for a full residential concrete removal project in Australia sits around $1,380, though prices can range from $585 to $2,790 depending on the project type and site conditions. For smaller concrete removal jobs, costs are typically higher per square foot compared to larger projects.

Key Cost Factors:

• Concrete thickness and slab size
• Type of concrete (reinforced or unreinforced)
• Site accessibility and location
• Labour rates in your area
• Disposal fees or recycling costs

Factors That Affect the Cost of Concrete Demolition

1. Concrete Thickness

Thicker concrete slabs require more effort and equipment to break up, increasing both labour and equipment costs. Standard residential slabs are usually around 100 mm thick, but driveways and patios may vary.

2. Reinforcement (Rebar or Wire Mesh)

Reinforced concrete is harder and more labour intensive to remove due to embedded steel reinforcement such as rebar or wire mesh. Expect higher labour costs and specialised equipment for these types of jobs.

3. Site Accessibility and Project Size

Limited access for equipment can increase labour time and project duration. Similarly, larger projects typically reduce the cost per square metre, while small jobs may attract higher rates. The complexity of the job, such as unusual shapes or the need to work around existing structures, can raise the overall cost of concrete demolition.

4. Labour and Local Rates

Local labour rates vary by city and state. Concrete demolition in major cities like Sydney, Melbourne, or Brisbane may be more expensive than in regional areas.

5. Disposal Costs and Recycling Options

Concrete disposal fees can range from $30 to $160 per tonne. However, recycling options may lower this cost. Recycled concrete can be repurposed for aggregate, reducing environmental impact and total cost.

Average Cost to Remove Different Types of Concrete

Concrete Slab Removal Cost

Standard concrete slab removal costs between $600 and $1,500, depending on thickness, size, and location.

Concrete Driveway Removal Cost

Concrete driveway removal typically ranges from $1,200 to $4,500. Factors include slab reinforcement, access for machinery, and disposal costs.

Concrete Patio Removal Cost

Removing a concrete patio generally costs between $800 and $2,000. Smaller patio slabs can often be broken up by hand, though reinforced or large slabs require machinery.

Concrete Stairs or Steps Removal Cost

The cost to remove concrete stairs ranges from $500 to $1,800, depending on number of steps, reinforcement, and removal complexity.

DIY Concrete Removal vs Professional Services

Costs and Equipment for DIY Concrete Removal

DIY concrete removal is possible for smaller areas but requires renting tools such as:

• Jackhammer or concrete saw
• Safety gear (gloves, goggles, dust mask)
• Skip bin for concrete disposal

Equipment hire costs can range from $406 to over $1,000 depending on duration and equipment type. Renting equipment for DIY concrete removal can cost a significant amount, often between $406 to thousands depending on duration.

Pros and Cons of DIY Concrete Removal

Pros:

• Saves on labour costs
• Good for small or surface-level slabs

Cons:

• Labour intensive and time consuming
• Risk of injury without proper safety precautions
• Requires correct disposal of concrete waste

Why Hire a Professional Concrete Demolition Contractor

Professional services bring experience, specialised equipment, and insurance to ensure the job is done efficiently and safely. Hiring a licensed contractor also means you won’t need to worry about permits, underground utilities, or complex slab removal. Certain concrete concreting tasks are better suited for professionals due to their complexity and risk involved.

Concrete Removal Process

Safety First: Protective Gear and Site Preparation

Before starting, it's essential to check for underground utilities and obtain necessary permits. Wear protective gear, isolate the work area, and sweep surrounding areas clear of debris. It is essential to check with your local council regarding underground utilities before concrete removal.

Cutting, Breaking, and Removing the Concrete

The removal process often begins with cutting or sawing the slab, followed by breaking the concrete into smaller sections using a jackhammer or skid steer. Reinforced slabs require more time to cut through steel mesh or rebar.

Disposal: Transporting and Recycling Old Concrete

After removal, concrete is loaded into bins or trucks for transport. Concrete disposal can be done via:

• Skip bin to landfill
• Local concrete recycling facility
• Hiring a contractor that includes recycling in their service

Can Concrete Be Recycled?

Yes. Recycling concrete is an eco-friendly and cost-effective alternative to landfill. Many recycling centres accept clean concrete debris and may even return crushed aggregate for use in your next project. Some local councils or recycling services offer incentives, reducing final cost and environmental impact. Recycling construction waste can lower the carbon footprint of your renovation.

Tips to Save Money on Concrete Removal

• Compare services from multiple contractors
• Consider recycling instead of landfill
• Book during off-peak periods
• Combine removal with concrete resurfacing or new slab installation for bundle rates
• Prepare the site ahead to reduce labour costs

Conclusion

Understanding the true concrete removal cost depends on your specific project, but being informed helps you budget effectively and avoid hidden costs. Whether you're removing an old concrete slab, patio, or driveway, weighing up DIY options against professional services can help you make the best decision.
