Tools & Materials You’ll Need

Concrete crack filler or sealant
Wire brush
Caulking gun (for sealant tubes)
Putty knife or trowel
Broom
Safety gloves and glasses
Pressure washer or hose (optional)
Step-by-Step Guide to Fixing Cracks
1. Clean the Crack
Use a wire brush to remove dirt, debris, and loose concrete. You can also use a leaf blower or pressure washer to clear the area.
2. Widen the Crack (If Needed)
For narrow cracks, slightly widen them using a hammer and chisel. This helps the filler bond better.
3. Apply the Crack Filler
Using a caulking gun or directly from the bottle, apply the filler into the crack until it’s slightly overfilled.
4. Smooth It Out
Use a putty knife or trowel to level the surface with the rest of your driveway.
5. Let It Cure
Follow the manufacturer’s curing time—usually 24–48 hours. Avoid driving over it until fully dry.
When Should You NOT DIY?
DIY is cost-effective, but not always the right fix. Call a professional if:
The crack is wider than ½ inch or looks like a web of cracks (craze cracking)
The concrete is uneven or sunken
There are signs of water pooling under the surface
Your driveway is older than 15 years and cracking in multiple spots
At this point, patchwork won’t last. It’s better to consult Leander Concrete Contractor for long-lasting solutions.
Frequently Asked Questions (FAQs)
1. Can I fix large cracks in my driveway myself?
For cracks wider than ½ inch, it’s best to get a professional inspection. DIY methods may only provide a short-term fix.
2. What’s the best filler for concrete cracks?
For small driveway cracks, a polyurethane-based concrete crack sealant works well because it stays flexible over time.
3. How long does a crack filler last?
Typically 3–5 years, depending on weather and how well the crack was prepared before sealing.
