Although concrete is a robust and versatile material, but it is not unbreakable. Concrete deteriorates over time due to damage, natural wear or weather, leaving behind structural changes and markings that can be unsightly or even dangerous. You normally have three alternatives when this occurs: repair, replacement, or restoration of your concrete surface or structure. Professional repair and restoration should be your first option for small and moderate damage because replacements can be expensive and complicated.
Concrete restoration, as opposed to concrete repair, addresses both damage and attractiveness.
Why is restoration of concrete is required?
- It can prolong the longevity of the concrete – Concrete has a lifespan of 50 to 100 years, and it can sometimes endure much longer, but regular maintenance can help it last longer and avoid premature ageing or deterioration. Prior to them developing into more serious damages, preventive maintenance can take care of tiny cracks, scuffs, and buckling.
- It can ensure safety – For uses including public sidewalks, patios, driveways, and parking garages, old or damaged concrete can pose a risk to both walkers and automobiles. By rebuilding your concrete, you’re making your surroundings safer and lowering your danger of slipping, tripping, and instability.
- It looks more attractive – An important aspect of managing your building or facility for commercial property owners is keeping it clean and presentable. Concrete may lose its vitality and colour over time due to UV fading caused by sunlight, acidic and chemical discoloration, and spills and stains caused by food, oil, and debris.
- It can improve insulation – Because concrete absorbs heat, it helps keep buildings from losing heat. Additionally, it can lower any extra indoor moisture that can seep through, improving the comfort of the space.
When you need to call a concrete restoration contractor? What are the signs?
- Cracks – Along walls and flooring, cracks can range in size from tiny hairline ridges to wide gaps. Numerous sorts of cracks with varying degrees of severity are brought on by factors like shrinking and settling. Even small cracks can result in an uneven walking surface or lower the energy efficiency of your building.

- Colour fading – Stains, fading spots, surface corrosion, and markings are examples of discoloration that don’t endanger the structural integrity of your facility but detract from its aesthetic appeal.
- Flaking – When it creates crystalline silica, this dust is filthy and exceedingly dangerous to breathe in.
- Spalling – When the surface of the concrete begins to separate into small or big pieces, it is said to be spalling.

- Unevenness – Surfaces are typically uneven due to either poor installation or deteriorated concrete. Water pools on uneven and sunken surfaces, where it can become dangerous when it freezes.
- Gaps – Concrete joints and the border of sidewalks and patios often have gaps in them. Gapping is caused by a variety of events, such as soil erosion or movement and seismic disturbances.
- Electricity cost – It might be time to evaluate your concrete structures and surfaces if your building’s electricity bills are higher than usual and you’re not sure why. Your utility cost will be impacted by compromised insulation.
What are the techniques for concrete restoration?
- Epoxy injection – One technique for repairing cracks and some gaps is epoxy injection. Epoxies form a solid bond that enables a compromised surface to keep supporting heavy loads. It is cost-efficient concrete restoration method but it has drawbacks.
Moving cracks cannot be repaired with epoxy injection, and it is not a replacement for addressing the root cause of the crack. You must first fix and dry any leaks or high-humidity locations where cracks are present since epoxy is incompatible with moisture.
- Polyurethane grouting – For severe concrete damage, a restorative compound called polyurethane grouting is used. It is the best solution for demanding or high-traffic applications since it is portable, quick-acting, and less intrusive. If you’ve fixed the problem’s core cause, you can typically resume normal activities soon after application because it’s clean and the cure time is short.
Polyurethane grouting, as opposed to epoxy injections, can withstand soiled or wet circumstances without compromising performance. However, it is not a structural repair and might not hold up under high tension.
- Concrete leveling – When the surface of concrete begins to sink or split, it must be raised from underneath by using the concrete leveling method. You may have heard the procedure referred to as slabjacking, lifting, or levelling.
Comparatively speaking, concrete levelling is less expensive and more invasive than removal and replacement. It is a good choice for property owners who have significant slope but do not want to or are unable to spend the money to remove and replace the existing concrete.
- Concrete removal and replacement – This is the last resort if all the above methods cannot apply. It’s also the ideal choice if concrete damage jeopardises a building’s structural integrity or if it causes it to stop functioning properly.
For instance, a concrete parking garage floor with numerous sizable gaps, cracks, and sinking is no longer usable by vehicles and is too far gone for restoration; replacement may be required.
Do you need concrete repair or resurfacing?
Your property may benefit most from resurfacing if: –
- You have several issues with the same concrete surface, including a variety of cracks, gaps, chips, and stains.
- It would be less expensive than multiple surface-level repairs.
- When improving the appearance of the concrete is your main goal.
- This method is only useful for surface-level difficulties; it has no influence on underlying problems or recurring ones.
A qualified contractor can assess the severity of your concrete problems and recommend the best course of action.
