Stamped concrete is durable and relatively easy to maintain. Regular maintenance includes sweeping away debris to keep it clean and prevent staining. It is also important to repair any cracks promptly to maintain its appearance and longevity. The concrete should be resealed every 2 to 4 years to protect the surface.

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.

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.
