While concrete driveways look nice when they are new, over time the concrete can chip, crack and crumble. Cracks and potholes form due to the freezing and thawing of water that has seeped under the driveway through smaller cracks, weed or grass growth in small cracks, and general wear and tear. Regular maintenance will prevent the need to replace the existing driveway. This is usually easy to do and requires up to a half day to complete depending on the condition and size of your repairs.
