Best concrete resurfacing pros near Thatcher, UT

No, hairline cracks in concrete are generally not a problem as they do not impact the strength and longevity of the concrete. Generally, cracks less than 0.3 millimeter wide don’t impact the structure. Hairline cracks can grow over time and weaken the structure, such as in a home foundation. Some hairline cracks can also cause leaks in a foundation. It’s important to watch the cracks to see if they grow. Contact a concrete contractor if you notice cracks exceeding 0.3 millimeter wide.

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.

The average cost to repair a concrete driveway ranges from approximately $830 to $2,800, with a typical project costing around $1,765. The price varies widely depending on the type and extent of the damage. Minor crack repairs can be as low as $0.10 to $0.15 per linear foot and may be a DIY project. More significant repairs are priced per square foot: replacing a damaged slab costs about $6 to $14, while raising or leveling sunken concrete costs $3 to $25. Resurfacing is another option, costing around $3 to $5 per square foot. Factors influencing the total price include the size of the affected area, whether reinforcement is needed, and labor costs.

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.
