Should You Replace or Fix Your Concrete Driveway? An Expert Guide
Kirwan, Australia – February 10, 2026 / Platinum Concreting Townsville /
Your concrete driveway takes a beating every day from vehicles, weather, and time. Eventually, you’ll notice cracks, stains, or uneven surfaces that make you wonder whether it’s time for repairs or a complete replacement. Making the right choice can save you thousands of dollars and years of frustration. This guide will help you understand when each option makes sense for your property.
Signs Your Concrete Driveway Needs Attention
The first step is recognising when your driveway has a problem. Small hairline cracks less than 6mm wide are normal and usually don’t affect the driveway’s function. However, wider cracks, multiple cracks spreading across the surface, or cracks that continue growing are warning signs that shouldn’t be ignored.
Sunken or uneven sections create tripping hazards and water pooling problems. If parts of your driveway have dropped or risen compared to the rest, this indicates issues with the base underneath. Stains from oil, rust, or other substances might seem purely cosmetic, but they can signal surface deterioration that goes deeper than you think.
Spalling, where the concrete surface flakes or chips away, exposes the aggregate underneath and weakens the entire structure. Surface pitting, numerous small holes across the concrete, and edges that are crumbling or breaking apart all indicate your driveway needs professional assessment.
When Concrete Repair Is the Right Choice
Repair works well when damage affects less than 25-30% of your driveway’s total area. If you have a few isolated cracks or a small sunken section, targeted repairs can restore function without the expense of full replacement.
The age of your driveway matters too. If it’s less than 15 years old and the damage is minor, repairs can extend its life significantly. The concrete’s overall condition is crucial—if the majority of the surface remains solid and structurally sound, repairs make financial sense.
Surface-level damage like minor spalling, small cracks, or cosmetic issues responds well to repair techniques. Professional concrete contractors can fill cracks, level small sunken areas, and resurface damaged sections. Townsville’s climate means driveways face intense heat and occasional heavy rain, but if your concrete has held up reasonably well despite these conditions, repairs can keep it functional for many more years.
Repairs are also the smart choice when budget constraints make replacement unrealistic in the short term. Quality repairs from experienced contractors like Platinum Concreting Townsville can buy you several years while you plan for eventual replacement.
When Full Replacement Makes More Sense
Replacement becomes necessary when damage covers more than 30% of the driveway. At this point, repair costs approach replacement costs, but you’re left with a patchwork driveway rather than a uniform, reliable surface.
Age is a major factor. Concrete driveways typically last 25-30 years with proper care. If yours is approaching or past this age and showing multiple problems, replacement gives you decades of worry-free use rather than ongoing repair expenses.
Widespread cracking throughout the surface indicates fundamental structural problems that repairs can’t fix. Major settling or heaving, where large sections have moved significantly, means the base has failed. Foundation issues, severe spalling across most of the surface, and drainage problems causing repeated damage all point toward replacement.
If you’re planning other property improvements, replacement might make sense even with moderate damage. Upgrading to decorative concrete, changing the driveway layout, or improving drainage are easier during full replacement.
Cost Comparison: Repairing vs Replacing Your Driveway
Minor repairs for small cracks or surface damage typically cost a few hundred dollars. More extensive repairs involving multiple areas or resurfacing can range from $1,000 to $3,000, depending on the size and complexity.
Full driveway replacement costs more upfront, usually between $65 $130 per square metre in Townsville, depending on the finish you choose. A standard residential driveway replacement might cost $5,000 to $12,000.
While replacement costs more initially, consider the long-term value. A new driveway lasts 25-30 years with minimal maintenance. Multiple repairs over 5-10 years can add up to similar costs while leaving you with an aging, patched surface. Calculate the cost per year of use—replacement often proves more economical over time.
How to Extend the Life of Your Concrete Driveway
Whether you repair or replace, proper maintenance extends your driveway’s life. Seal your concrete every 2-3 years to protect against moisture, stains, and Townsville’s harsh UV rays. Clean spills quickly, especially oil and chemicals that can deteriorate the surface.
Address small cracks immediately before they expand. Keep drainage clear, so water flows away from the concrete. Avoid using harsh de-icing chemicals and be cautious with heavy vehicles or equipment that exceed the driveway’s design load.
