Best concrete resurfacing pros near Aurora, SD

A layer of exposed aggregate concrete should be 1 to 2 inches thick if you’re installing it on top of existing concrete. If you’re pouring a new slab with the finish, slab thickness will depend on the application. Exposed aggregate concrete driveways should be 4 to 6 inches thick in most cases or 8 to 12 inches for commercial vehicles. Sidewalks, patios, and walkways should be 4 inches thick.

Small cracks should be filled with a flexible crack filler, like a rubberized asphalt-emulsion crack filler or a flexible masonry crack filler. Larger cracks need something a bit more solid to prevent further movement and to avoid having to use too much of the flexible filler. For concrete, you can use a concrete backer rod while asphalt can handle sand, gravel, or even dirt.

Deciding whether to repair, resurface, or replace your concrete driveway depends on its age, condition, and the cost of the potential work.

If your driveway is over 20 years old and showing significant deterioration, replacement is often the best option. Similarly, if the cost of repairs is 50% or more of the replacement value, it's more cost-effective to replace it. For newer concrete with minor issues, resurfacing can be a good choice, especially if you have maintained it well with regular sealing.

For a definitive recommendation, contact a reputable concrete contractor. They can assess the driveway's condition and advise whether repair, resurfacing, or a full replacement (which costs between $1,400 and $12,100) is the most sensible path.

The method used to repair cracks in your concrete driveway will depend on the extent of the damage, but the most common method for small cracks is to use a driveway resurfacing compound. This solution is either cementitious or made of polyurethane, and it will seal the crack and make your driveway appear undamaged. 

For more severe cracks, you will likely need to hire a professional driveway repair service. They can use mudjacking, epoxy injections, partial driveway replacements, or a combination of these to fix more serious cracks in your concrete driveway and to prevent recurring issues.
