Get matched with top concrete resurfacing pros in Floyd, VA

The best solution to fix a foundation crack in your basement floor depends on the underlying cause. If you just have hairline cracks from settlements that are no longer growing, the best option is to seal them with a crack sealant. If the cracks continue to grow, one edge rises above the other, or there are signs that water is getting in through the crack, a professional repair will be necessary. Depending on the root cause, your professional may employ foundation underpinning or some other type of stabilization, seal the cracks, or install a drainage system.

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.

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.

Regularly inspecting your foundation—at least the visible sections—for signs of foundation issues like moisture and pest infestation is a good way to identify slab leaks early, as is keeping an eye and ear out for water damage to indoor building materials, above-average water bills, sounds of running water when no fixtures or appliances are on, and indoor humidity that causes the temperatures to feel more extreme. If you do find any issues, contact a plumber right away to check it out for you.
