They can be the biggest culprit of water under your slabs. Notice how the caulking is slightly lower than the concrete slab around it. This protects the caulk from wear and tear of people walking and driving over it.
In this guide, you will learn the steps that can, and should, be taken to help extend the life of your concrete and keep your home safe and beautiful for years to come. These include the types of caulk to use, as well as best practices for getting those concrete driveway cracks repaired and long-lasting. Concrete driveway crack repair is not all that different than any other concrete crack repair, except for one big difference; the size of the cracks. Because driveway slabs are normally much bigger than sidewalks and other concrete areas, the cracks can be longer, and oftentimes wider.
When we talk about concrete driveway crack repair, we are typically talking about two processes. The first is concrete leveling, and the second is caulking and sometimes grinding the crack. We discuss concrete leveling in-depth on other pages of this site here's a detailed guide on what is involved in concrete leveling but for our purposes, we first want to get any slabs that are out of level from each other back into alignment.
This involves a process of pumping some material under the lower slab and gently lifting it until it is the same level as the slabs around it.
This could involve intact slabs that have sunk at expansion joints or slabs that have broken and partially sunk on one side of the crack. Depending on how out of level your driveway is, this could be simply moving one slab, or it could involve lifting and leveling nearly every slab in the driveway.
Once the slabs are leveled with each other, then the cracks or expansion joints are filled with a flexible caulk to keep water from flowing under the slab. This is the primary purpose of concrete driveway crack repair. If water is flowing under your driveway, it is only a matter of time before the slabs will begin to sink. This is precisely why we always recommend caulking the cracks and joints after we level your concrete slabs.
With the right tools, material, and patience, caulking your concrete driveway cracks is something you can do yourself. In the end, you may want to hire an experienced professional discussed more below but if you're the handy, do-it-yourself type then this might be a project you can tackle as a weekend project.
Once the cleaner has been applied, a high pressure nozzle is attached to the washer and the surface is thoroughly cleaned. Be sure to clean out the cracks out as well, removing any dirt or loose concrete so the patching material will adhere to the concrete. After allowing the material to dry overnight, a much thinner batch of resurfacer is mixed up.
Before applying it, wet the concrete down to prevent it from drying out too quickly. Once everything is ready, the resurfacer is spread on the slab using a rubber squeegee. Getting a nice even coat without lap mark can take a bit of practice. When the resurfacer starts to set up, a broom with an extended handle can be used to give the fresh concrete surface texture and prevent it from becoming slippery when wet.
The resurfacer can handle foot traffic after it has set up for about six hours, and cars can drive on it once it has cured for 24 hours.

Thank you, Wayne. To prepare concrete acid etching and pressure watching is the best option. Muriatic Acid is commonly found at most larger hardware stores, paint supply stores, lumber companies, swimming pool supply stores, Wal-Mart, Kmart, etc.
See our advanced instructions for how to acid etch concrete. Take extra time to clean out all the cracks and crevices you may see, no matter how small or thin. You want your concrete patching to have a good surface to adhere to.
