Concrete driveways are built to be strong and long-lasting, but they are not invincible. Over time, even the most well-poured concrete can develop cracks. These cracks might start small, but if ignored, they can grow into bigger problems ruining the look of your driveway and potentially leading to costly repairs.
If you have noticed cracking in your concrete driveway, don’t worry, it’s a common issue and one you can often tackle yourself. In this guide, you will learn exactly how to fix cracks in a concrete driveway, what materials to use, and how to prevent future cracking. Whether you are a DIYer or a first-time homeowner, we’ll walk you through the process in a straightforward, no-nonsense way.
Why Concrete Driveways Crack
Before jumping into the fix, it helps to understand what causes cracks in the first place. The most common causes of driveway cracks include:
Freeze-thaw cycles – Water enters tiny pores, freezes, and expands.
Heavy vehicle loads – Especially from trucks, RVs, or delivery vans.
Soil movement or settling – Shifts beneath the slab cause stress.
Improper installation – Weak base, no control joints, or poor mix.
Drying shrinkage – Concrete loses moisture too fast while curing.
Even with perfect installation, it’s natural for driveways to crack over time. The goal is to fix them early and take steps to prevent further damage.
Step-by-Step: How to Fix Cracks in Concrete Driveway
1. Clean the Crack Area Thoroughly
Start by removing dirt, weeds, loose concrete, and debris from the crack. A wire brush, screwdriver, and a shop vacuum work great. For deeper cleaning, use a pressure washer.
Why this step matters: If the crack isn’t clean, the filler won’t adhere properly. A strong bond means longer-lasting results.
2. Assess the Crack Type
Not all cracks are created equal. Fixing hairline cracks in driveway is very different from repairing larger ones. Here’s a quick breakdown:
Hairline cracks (less than 1/8 inch wide): Usually cosmetic.
Medium cracks (1/8 to 1/2 inch wide): Often caused by minor settling or shrinkage.
Wide cracks (larger than 1/2 inch): May indicate structural issues or poor installation.
Understanding the type helps you choose the right driveway crack repair products.
3. Choose the Right Crack Filler
There are several types of crack fillers available. The best concrete crack filler for driveway depends on your crack size and weather conditions.
Latex or acrylic fillers: Good for small, non-structural cracks.
Polyurethane sealants: Flexible and great for weather-exposed areas.
Epoxy for driveway cracks: Ideal for deeper or structural repairs.
Quikrete driveway crack filler: A trusted brand for DIY repairs, available at most hardware stores.
Make sure to read product labels and choose one that suits your specific needs.
4. Apply the Crack Filler
Once the area is clean and dry, it’s time to get to work. Follow these steps for a successful DIY driveway crack repair:
Load filler into a caulking gun (if applicable).
Apply slowly, filling the entire depth of the crack.
Smooth the surface with a putty knife or trowel.
Let it cure, following the product’s instructions.
Pro tip: For wider cracks, insert foam backer rods before applying filler. It saves on material and ensures proper depth for sealing.
5. Seal the Repaired Area
After fixing the cracks, sealing your driveway is crucial. A concrete sealer protects the surface from moisture, UV rays, chemicals, and more.
Use a driveway crack sealer application roller or sprayer.
Wait for a dry, warm day with no rain in the forecast.
Apply evenly and allow to dry fully before walking or driving on it.
Sealing helps extend driveway lifespan and prevents new cracks from forming.
How to Patch Concrete Driveway Sections
When your concrete driveway has more than just surface cracks like broken, sunken, or crumbling sections it may be time for a more involved repair. Learning how to patch concrete driveway sections can help restore both function and curb appeal. Though it takes more effort than simple crack filling, it offers long-term results.
Cut Out the Damaged Section Using a Circular Saw with a Masonry Blade
Start by marking the damaged area with chalk and then carefully cut along those lines using a circular saw fitted with a masonry blade. Cutting clean edges helps the new concrete bond better and creates a more seamless finish. Wear safety gear especially eye protection since concrete dust can be harmful.
Remove the Broken Concrete and Clean the Base
After cutting, break out the damaged section using a hammer and chisel or a demolition hammer. Be sure to remove all loose pieces and debris. Then clean the base thoroughly, removing any dirt or dust. A clean, solid base is essential for ensuring that the new concrete sets properly and stays in place.
Pour New Concrete, Match the Level and Texture, and Let It Cure Properly
Mix a fresh batch of concrete and pour it into the cleaned-out section. Use a trowel to spread and level it so it aligns perfectly with the surrounding driveway. Try to match the original texture for a consistent look. Allow it to cure fully usually 24–48 hours before using the driveway again.
Why This Method Works
Though more labor-intensive than filling cracks, patching broken sections of your concrete driveway ensures a longer-lasting and more stable repair. It also prevents moisture from seeping into deeper layers, which could cause future cracking or erosion. This method brings back both strength and a uniform appearance to your driveway.

Final Tip: Match Product to Climate and Crack Type

Resurfacing a Concrete Driveway: When and How
Sometimes, a driveway is too far gone for simple crack repairs. If your concrete has multiple cracks, stains, or a tired appearance, resurfacing may be your best option. It’s more affordable than a full replacement and can completely refresh the look of your driveway while restoring its smooth, even surface.
Step 1: Clean and Patch First
Begin by cleaning the entire surface thoroughly using a pressure washer to remove dirt, oil stains, and loose debris. Patch any deep cracks or holes with a concrete repair product. This step ensures the resurfacer bonds properly and creates a smooth, uniform finish that lasts through the seasons.
Step 2: Mix the Concrete Resurfacer
Most resurfacers are available in dry or pre-mixed form. If using a dry mix, add water slowly and stir until you get a pancake batter-like consistency. Use a paddle mixer for best results. Work in small batches, as resurfacing compounds set quickly, especially on warm days.
Step 3: Apply Evenly with a Squeegee or Trowel
Pour the mixture onto the driveway and spread it evenly using a long-handled squeegee or a trowel. Work methodically in sections to maintain a consistent thickness. Smooth it out as you go to avoid ridges or high spots. It’s a bit of work, but the results are worth it.
Step 4: Add a Finish for Texture and Grip
To avoid a slippery surface, apply a texture finish while the resurfacer is still wet. A broom finish is popular for driveways because it adds just enough grip without looking rough. Lightly drag a broom across the surface in one direction to create subtle, uniform lines.

How to Seal Driveway Cracks for Long-Term Results
Sealing your driveway after repairing cracks is a key step that many skip—but it’s essential for longevity. A good sealer acts like a shield, protecting your concrete from water, chemicals, UV damage, and freeze-thaw cycles. Here’s how to get it done for lasting, professional-looking results.
Step 1: Clean the Surface Again
Once the crack filler has cured, clean the entire area again. Use a broom or blower to remove dust and debris, and wash off any leftover residue. The cleaner the surface, the better the sealer will adhere, which means better protection and a smoother finish.
Step 2: Choose a Quality Concrete Sealer
Not all sealers are created equal. Look for a weather-resistant concrete sealer that’s made for driveways. Acrylic sealers are a popular choice for their ease of use and durability. For extra protection, consider a penetrating sealer that goes deep into the concrete to block moisture from within.
Step 3: Apply Thin, Even Coats
Use a roller or garden sprayer to apply the sealer in thin, even coats. Don’t rush—work in sections and follow the grain of the concrete. Avoid puddling, as too much product can leave shiny or slippery spots. Let the first coat dry completely before deciding if a second is needed.
Step 4: Let It Cure Before Use
Drying times vary by product, but most sealers need 24–48 hours before you can walk or drive on them. Make sure the forecast is dry and sunny during this time. Once cured, the sealed surface will help keep water out and cracks from coming back, preserving your hard work.
Prevent Cracks in Concrete Driveway
Prevention is better than cure, especially when it comes to concrete. Here’s how to prevent cracks in concrete driveway:
Ensure proper drainage around your home.
Avoid using salt during winter; use sand instead.
Seal the driveway every 2–3 years.
Park heavy vehicles in varied spots to distribute weight.
Fix small cracks as soon as they appear.
Following these tips helps you keep your driveway looking great and reduces long-term repair costs.
Concrete Driveway Maintenance Tips

FAQs:
What is the best product to fill cracks in a concrete driveway?
The best product depends on the crack size. For small to medium cracks, a self-leveling sealant like Sikaflex or Quikrete Concrete Crack Seal works great. For deeper or structural cracks, epoxy-based fillers offer better strength and durability. Always check if the product is weather-resistant, especially for outdoor use.
Can I repair concrete driveway cracks myself?
Absolutely! Most concrete driveway cracks can be repaired as a DIY project. With basic tools like a caulking gun, filler, and a trowel, you can fix cracks and seal them in a few hours. Just make sure to clean the area thoroughly and follow the product instructions for best results.
How do I prevent cracks from coming back in my driveway?
Prevent future cracks by sealing your driveway every 2–3 years, maintaining proper drainage, and avoiding heavy loads in one spot. Don’t use harsh chemicals or salt in winter, and patch any new cracks as soon as you spot them. Regular maintenance is key to a long-lasting concrete driveway.
Should I be worried about hairline cracks in concrete?
Hairline cracks are usually not a big deal and often occur from natural shrinkage or temperature changes. Still, it’s smart to seal them early to prevent water from seeping in, which could make the cracks worse over time. Monitoring them and taking action quickly helps avoid larger repair needs later.
Is resurfacing better than patching concrete cracks?
Resurfacing is a great option when your driveway has many cracks or looks worn overall. It gives your driveway a fresh finish without full replacement. Patching is better for isolated cracks. If aesthetics and long-term performance matter, resurfacing can be a smart, cost-effective solution for concrete driveways.
