Like all building materials, concrete weakens with age due to temperature changes, moisture, and cracks that widen over time. Keep in mind that there are ways to keep your concrete strong by resealing it every two to three years, avoiding harsh cleaning chemicals, and addressing small cracks as quickly as possible.

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.

Concrete blemishes such as chipped steps or small cracks are fixable with patching. For bigger jobs, including driveway repair and cracks wider than a 1/4 of an inch, patches will only serve as a temporary fix. Resurfacing is ideal when the surface is showing more widespread wear—like if it’s pitted, rough, or has lots of cracks. Resurfacing gives your concrete a fresh, like-new appearance without needing a full replacement.

When the concrete is severely cracked, sinking, or otherwise structurally unsound, replacing it might be your best option. Replacement ensures the safety and longevity of the surface in this case.
