At Burton’s Concrete, we know that even the strongest surfaces can show a few cracks over time. If you’ve been wondering how to fix cracks in concrete, you’re not alone.
Cracks can pop up from weather, wear, or just plain aging—and while they’re common, they don’t have to turn into a major headache. Whether it’s a small surface line or something deeper, we’re here to walk you through what to do next—whether that’s a quick weekend patch job or calling in your friendly neighborhood experts (that’s us).
Why Concrete Cracks (And How to Fix Cracks in Concrete the Right Way)
While concrete is tough—but it’s not invincible. Shifting ground, temperature changes, freeze-thaw cycles, tree roots, and even heavy traffic can all lead to cracks. Some are just cosmetic, while others are signs your concrete needs a little TLC.
Before you grab a trowel, let’s figure out what kind of crack you’re dealing with:
- Hairline cracks: Usually under 1/8″, these are mostly aesthetic and don’t threaten the structure.
- Medium cracks (1/8″–1/4″): These may widen with time, especially with moisture and weather changes.
- Large or uneven cracks: If the surface is lifting or dropping, or if cracks are wider than 1/2″, it might be time to call in the pros.
Tools & Materials You’ll Need:
- Crack filler or patching compound
- Wire brush or pressure washer
- Masonry caulk or trowel
- Concrete cleaner
- Concrete backer rod (for deeper cracks)
- Safety gloves and glasses
How to Fix Narrow Cracks (Under 1/4 Inch)
These hairline to minor cracks are often just on the surface, and while they’re not urgent, they should still be sealed to keep water from sneaking in.
Here’s how to repair them:
- Clean the crack thoroughly with a wire brush and rinse it with water. Let it dry.
- Apply a liquid or tube-based concrete crack filler. Look for one labeled flexible or weather-resistant.
- Smooth it out with a putty knife and remove any excess to blend with the surface.
- Let it dry and cure, following the manufacturer’s directions.
🛠️ Pro Tip: Choose a crack filler that matches your concrete color for a clean finish.
How to Fix Wide Cracks (Over 1/4 Inch)
Wider cracks may go deeper, and if left unchecked, they can lead to bigger problems like heaving, sinking, or full section breakdown.
Here’s what you’ll need to do:
- Use a chisel to widen the base of the crack slightly—this helps the filler grip better.
- Clean out all debris using a brush, blower, or shop vac.
- Insert a backer rod (a flexible foam strip) to limit how much filler you need and create a uniform base.
- Mix and apply a patching compound or heavy-duty concrete mix, pressing it into the crack.
- Smooth and level it using a trowel.
Cure the patch as instructed—some take hours, others a couple of days.
