Concrete surfaces, such as driveways, patios, and walkways, are built to last but can show signs of wear and tear over time. Cracks, stains, and surface damage are common, and when these issues arise, homeowners often face the dilemma between concrete resurfacing vs replacement.
This decision can impact both the cost and appearance of your property, making it important to understand the benefits and drawbacks of each option.
This article will walk you through concrete resurfacing and replacement, helping you decide which solution is best for your situation.
What is concrete resurfacing
Concrete resurfacing is a process where a new layer of material is applied over existing concrete to restore its surface and appearance. This method is commonly used to address minor cracks, stains, and surface wear without removing the entire slab.
Process overview
- Surface preparation: The existing concrete is thoroughly cleaned and repaired to remove dirt, debris, and minor imperfections.
- Bonding agent application: A bonding agent is applied to the old surface to ensure the new layer adheres properly.
- Resurfacing material: A specialized compound, such as polymer overlays or jewel stone, is spread over the existing surface.
- Finishing: Once the new layer is applied, it’s finished to match the desired texture or design.
Common Applications
- Concrete Driveway Resurfacing
- Patios resurfacing
- Walkways resurfacing
- Pool decks resurfacing
What is concrete replacement?
Unlike resurfacing or concrete levelling, concrete replacement involves a complete replacement of the existing concrete and pouring a new slab. This process is necessary when the concrete is severely damaged or the base is compromised.
Process overview
The process begins with the demolition and removal of the damaged concrete, followed by cleaning and inspecting the site to ensure proper drainage. Once the site is prepared, new concrete is poured into place and finished to create a smooth surface.
Concrete replacement is often required when the slab shows significant structural damage, such as deep cracks or settling, or if there are foundation issues that require a complete rebuild. It’s also the best option when the concrete is beyond repair, and resurfacing will not restore its integrity.
This option is most common for structural slabs in foundations, basements, or severely damaged existing driveways needing a driveway replacement, or patios, and sinking or uneven surfaces that pose safety risks.
Key differences between resurfacing and replacing concrete surfaces
| Feature | Resurfacing | Replacement |
|---|---|---|
| Cost | Lower | Higher |
| Time | Faster | Slower |
| Durability | Good (with proper prep) | Excellent |
| Aesthetics | Customizable | Can be customized post-install |
| Environmental Impact | Lower (no demolition) | Higher |
Signs your concrete may be a candidate for resurfacing
Resurfacing can breathe new life into your concrete without the need for a complete replacement. It’s a great choice when the damage is cosmetic rather than structural. Here are some signs that your concrete may be a good candidate for resurfacing:
- Surface-level cracks and scaling: Minor surface damage that doesn't affect the structural integrity.
- Minor discoloration or pitting: The surface looks worn but is still solid beneath.
- Stable base: The underlying base is still intact, with no shifting or major settling.
- Aesthetic upgrade: If you’re looking to improve the look of your concrete without major demolition, resurfacing offers a quick solution.
Signs your concrete needs full replacement
In some cases, the damage is too extensive for resurfacing to be effective. If any of these issues are present, you may need to replace your concrete:
- Large, deep cracks or heaving: These are signs of significant structural problems that resurfacing cannot fix.
- Foundation issues: If the concrete slab has shifted or settled, the base is likely compromised, requiring a full replacement.
- Rebar corrosion: If the steel reinforcement bars (rebar) inside the concrete are rusting, the slab’s integrity is severely compromised.
- Water drainage problems: Improper drainage can weaken the concrete over time, making replacement the best option.
- Multiple failed repairs: If previous repairs have not resolved the issues, a new slab may be necessary.
Cost comparison
Understanding the cost differences between resurfacing and replacement is crucial for making an informed decision.
Resurfacing costs
Resurfacing typically costs between $3 and $10 per square foot. This price can vary based on factors like the complexity of the design, the type of resurfacing material used, and the condition of the existing concrete.
Replacement costs
Concrete replacement is more expensive, generally ranging from $6 to $20 per square foot. The cost depends on the amount of demolition required, the cost of materials, and the size and accessibility of the area.
Factors influencing pricing
Both resurfacing and replacement costs depend on several factors, including:
- The amount of preparation work needed
- The square footage of the area
- Additional features such as decorative finishes or textures
Pros and cons of concrete repair vs replacement
Resurfacing pros & cons
Pros
- Cost-effective: Resurfacing is much cheaper than replacement, especially for minor damage.
- Quick installation: The process can often be completed in a day or two, allowing you to use the surface again quickly.
- Aesthetic upgrades: Resurfacing offers a chance to improve the appearance of your concrete, with various textures and finishes available.
Cons
- Not suitable for severe damage: Resurfacing won’t fix deep cracks, foundation issues, or large structural damage.
- Requires proper prep: If the underlying surface isn’t properly prepared, the new layer may not adhere well, leading to premature wear.
Replacement pros & cons
Pros
- Long lifespan: Replacing the concrete gives you a fresh start, ensuring durability and strength for many years.
- Structural integrity restored: If there are issues with the foundation or rebar, replacement addresses these problems, providing a more stable surface.
Cons
- Higher cost: Replacement is significantly more expensive than resurfacing, especially when dealing with large areas.
- More disruptive: The demolition and installation process is more time-consuming and may require you to temporarily avoid the area.
How to decide – questions to ask yourself
Before making a decision, ask yourself the following questions:
Is your concrete structurally sound? If the base is solid, resurfacing might be all you need. If not, replacement is the way to go.
What’s your budget? If you’re looking to save money and the damage is cosmetic, resurfacing is a great option.
Are you looking for cosmetic or functional improvements? Resurfacing is ideal for cosmetic fixes, while replacement is best for functional repairs.
How quickly do you need the project completed? Resurfacing is faster and less disruptive than replacement.
Are you planning to sell your home soon? If so, replacing severely damaged concrete might be worth the investment to improve your home’s value.
Why choose concrete replacement
Concrete replacement is the better choice when dealing with serious issues like foundation problems or extensive cracking. It restores both the aesthetic and structural integrity of the surface, giving you a solid foundation for years to come.
Why choose concrete repair
If your concrete is only showing cosmetic damage, concrete resurfacing offers a quick and cost-effective solution. It improves the surface's look without the hassle of complete demolition. Plus, it's a great option if you want to upgrade the appearance of your concrete without major disruption.
When to call a professional
It's always a good idea to have a professional assess your concrete before making a final decision. A concrete expert can inspect your surface to identify any hidden problems and help you weigh the pros and cons of resurfacing vs replacement. Getting an estimate for both options allows you to choose the one that best suits your needs and budget.
