How To Repair Cracks In Concrete Driveway?

To repair cracks in a concrete driveway, clean the cracks to remove debris, then fill them with a concrete crack filler or patching compound, smoothing the surface with a trowel. Allow the filler to dry as per the manufacturer's instructions, and apply a sealant over the repaired area to protect it from future damage. 


Concrete driveways are a popular choice for homeowners due to their strength and longevity. However, they are not impervious to damage.
