Concrete Leveling questions, answered by experts

Yes, but large projects benefit from professional delivery and mixing to ensure proper consistency and durability.

You have different options depending on the scale of repair needed. If you are repairing minor cracks that are between ¼ inch to 1.5 inch wide and less than half an inch deep, a self-leveling polyurethane sealant would be your best choice. Polyurethane sealants dry to the touch within one to two hours. Since they come in a tube applier, you also have the option to complete the repair without emptying out your garage.

Yes, masonry is more expensive than concrete because the labor is much more involved. With masonry, your expert will build your project from the ground up, one piece at a time, ensuring they use the proper amount of mortar or grout during construction and keeping the project level or plumb. Pouring concrete can also be labor-intensive, but it’s a bit less involved. It requires building a mold, pouring the concrete, and letting it cure. The less intensive labor makes concrete a more affordable option in most cases.

Concrete should be at least 2 inches thick to maintain its stability and quality. Most concrete slabs fall between 4 and 6 inches thick, but you should be careful not to make the new slab too high or heavy. If you're considering a stamped concrete overlay, hire an experienced stamped concrete contractor to determine the ideal concrete thickness.

Pervious concrete should be between 4 and 8 inches thick to drain water properly. Surfaces like parking lots and driveways should be at least 6 inches thick to accommodate the weight of vehicles, while patios and walkways may be poured between 4 and 6 inches thick. There’s no standard for pervious concrete thickness, but in most cases, the more weight the surface will need to hold, the thicker it should be.
