Minor hairline cracks in your concrete may not look pretty, but they’re often not serious. It’s when concrete cracks are larger—wide enough that you can slide a credit card into it—that you need to worry. If you monitor a crack and can trace its active expansion over time, you’ll definitely want to call in a pro to inspect it and, potentially, repair it. Want to prevent cracks in your garage and driveway concrete in the future? Stay on top of sealing. Here’s how to seal your concrete garage floor and driveway.

No, wet concrete will not bond to dry concrete without an additional bonding agent. The common alternative is adding a sand or gravel layer under a concrete slab to enhance bonding and create a stable foundation. The right choice depends on the height and thickness of your two slabs, local laws, and the use of the specific concrete slab.

Small cracks should be filled with a flexible crack filler, like a rubberized asphalt-emulsion crack filler or a flexible masonry crack filler. Larger cracks need something a bit more solid to prevent further movement and to avoid having to use too much of the flexible filler. For concrete, you can use a concrete backer rod while asphalt can handle sand, gravel, or even dirt.

Concrete leveling is absolutely worth it if you have sunken concrete slabs and want to restore them to level, especially if the slab is part of your home foundation. Concrete leveling is less than half the price of replacing concrete sidewalks, patios, walkways, and pool decks, and it’s about a quarter of the cost of replacing a foundation. If you also treat the underlying problem, it can be a worthwhile and permanent solution.
