Best concrete resurfacing pros near Payson, AZ

For thin driveway cracks that aren’t widening or lengthening, a polyurethane crack filler is usually the best way to seal the crack and prevent further damage from water and ice. If you have cracks that are more than ⅛-inch wide or driveway cracks that continue to grow, you should call in a professional driveway repair company to fix underlying problems—like insufficient support from the soil underneath—before filling in the cracks. An epoxy sealant is a better option for wider cracks after the surface is leveled and the underlying problem is fixed.

A concrete overlay on an existing slab can range from 1/4 of an inch to 2 inches thick, though a minimum of 2 inches is often recommended to ensure stability and quality. The ideal thickness depends on the condition of the existing concrete and the depth of any planned designs or imprints. Before applying the overlay, it's important to repair and clean the surface, then apply a primer. For specialized work like a stamped concrete overlay, hiring an experienced contractor is recommended to determine the correct thickness and ensure the new layer isn't too high or heavy. For context, most standard concrete slabs are between 4 and 6 inches thick.

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.

There’s no legal requirement that states that you need rebar in a concrete driveway, but since the slab will be supporting heavy vehicle loads, it’s always a good idea to pay a bit more for rebar reinforcement. Your driveway will be much more likely to crack if you don’t reinforce it with rebar. Driveways that need to support commercial vehicles or provide parking for multiple vehicles at once should always include rebar reinforcement. If you’re pouring concrete over asphalt or pouring concrete over an existing slab, you may not have enough depth for rebar, meaning an increased risk of cracking.
