I always get asked to repair cracks in concrete driveways, after all its what I do. Most cracks occur in concrete from movement underneath the slab. The crack occurs at the stress point in the slab. Concrete is so hard that it really has no flexibility to it so it has to give way by breaking.
The time comes to repair and should be done before old man winter makes it worse. Water can get into the crack, freeze and break the concrete away exposing more problems. The crack will need to be chased then bonded with repair material that is stronger than concrete. If the slab is still moving this can be a problem down the road as the concrete can break again. Slab jacking can help bring the slab level again and remove some of the stress so the repair can have better success. Once bonded the crack can then be filled with concrete.
Once you fix the crack and it is filled you still have an ugly crack. You can then coat with protective coating to hide all the repairs and make your driveway look new again!
Repairing your driveway can save you thousands of dollars versus replacement. New technology advancements in polymer modified concrete resurfacing products have made it possible. Now you can have your driveway resurfaced for less than half the cost of replacement. When using qualified installers you can have full confidence that this repair will last for years to come. In the past the only option was to tear out your old concrete driveway and take it to the landfill. This of course is not the most environmentally friendly option. The secret to any long lasting surface repair is preparation and the use of the right type of product for the job.

Brand new look and enhanced curb appeal too.
Tips to ensure a resurfaced driveway that will last:
- Clean and remove all loose material.
- Apply proper preparation including crack and deep fill repair.
- Installation of an approved primer to create that bond for the surface material.
- Ensure there is a profile for the surface material to “grab” on to.
- Always cut in expansion joints up through the repair.
- Seal the concrete with an approved sealer. Very important!
- HAVE A PROFESSIONAL DO THE WORK!
