Get matched with top concrete resurfacing pros in Wrangell, AK

Efflorescence can damage a concrete slab for two to three years. After that, it resolves on its own once the surrounding salts are gone.

Yes, you can pour new concrete over old concrete, but you need to apply a concrete bonding agent to the existing concrete to ensure the new concrete sticks. Keep in mind that even with a bonding agent, large cracks and other flaws will still come through. If the concrete has heaved, settled, or cracked, pouring new concrete on top won’t address any root structural problems. Removing the existing concrete and rebuilding will be your best solution in that case.

A resurfaced concrete driveway typically lasts between 8 and 15 years, with an average of around 10 years. The actual lifespan depends on several factors, including the quality of the original concrete, how well the resurfacer was applied, the amount of traffic it endures, and the local climate. Exposure to intense sunlight, rain, snow, and frequent temperature fluctuations can weaken the surface more quickly. To prolong its life, you should reseal the concrete every one to three years and patch any small cracks as they appear.

Concrete resurfacing and concrete overlay are terms often used interchangeably to describe the process of applying a new, thin layer of pre-blended concrete over an existing slab. This process enhances the durability and appearance of the concrete, giving it a fresh look without the high cost of a full replacement. The new layer is typically between 1/4-inch and 1-inch thick, significantly less than the 4 inches required for a new slab, and can be stamped, colored, or textured for a custom finish.

While the terms are often considered the same, their meaning can sometimes vary by contractor. Some may use "overlay" to describe a thicker application that adds structural integrity, while "resurfacing" might refer to a thinner layer intended for cosmetic upgrades. Other common names for this process include concrete restoration, concrete refinishing, and concrete rejuvenation.
