Get matched with top concrete resurfacing pros in Bayard, NM

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.

The biggest downside to resurfacing concrete is its lifespan. Concrete resurfacing lasts for five to ten years, on average, while a new concrete slab would last for 20 to 30. The cost of concrete resurfacing is much lower, but you get more value from full replacement. Resurfacing also doesn’t address any underlying issues with your slab, so you may need additional repairs, like mudjacking.

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.

Whether resurfacing concrete is worth the cost depends on the condition of the underlying slab. Resurfacing can be a good option if the concrete is in decent condition with only minor issues like standard wear and tear, small cracks, chips, or discoloration. In these cases, resurfacing adds a protective layer that can extend the concrete's lifespan without the high cost of a full replacement.

However, if the concrete has significant damage—such as deep cracks, peeling, sinking, or is broken up—resurfacing may not be worth it. The new overlay is only as good as the concrete beneath it, and existing problems like peeling and cracks are likely to show through the new surface. In situations with severe damage, replacing the entire slab is often more cost-effective in the long run and will yield a better result.

To make the best decision, it's recommended to have a licensed concrete specialist inspect the damage and determine if resurfacing is the right choice for your situation.
