Best concrete resurfacing pros near Prewitt, NM

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

Rebar is an essential part of reinforcing a basement floor, as not having it can impact its structural integrity. It helps absorb the tension factors that contribute to cracks in your floor and strengthens its load-bearing capabilities by evenly distributing the weight. Not including rebar could lead to an unstable floor, so don’t skip it!

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.

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.
