Considering that many homes have front-facing driveways, it is a good way to help improve your home's curb appeal.

The most common cause of concrete cracks is standing water, which, over time, works its way into the concrete and expands and contracts according to the temperature. Before you begin fixing the actual crack, think long and hard about how you can eliminate the cause of the problem. Preventing further damage is vital to the overall success of your repair job.
Then, rinse the area thoroughly, scrubbing with a wire brush to dislodge any loose, lingering particles.

Prevent future cracks in concrete by following a few tips from the pros. Disclosure: BobVila. You agree that BobVila. Often, an uneven sidewalk may be the result of a slab being raised rather than sunk. This, too, can create a hazard, especially when left untreated. Instead, most raised sidewalks can be fixed faster and far less expensively by using sidewalk leveling to raise the slabs on either side of the affected slab.
When carefully leveled by an experienced professional, this creates a gentle, even slope—again, avoiding replacement while thoroughly fixing the issue. Other times, an uneven sidewalk can resemble a teeter-totter.
One side lifts up, while the other sinks down. This is another case where a professional sidewalk leveler with the right tools and experience can know exactly where to drill holes and fill to a precise level in order to raise one side back to its proper position. Sidewalk replacement will almost always be more expensive and labor-intensive than repairing it through our sophisticated leveling process.
In short, sidewalk repair requires less labor, time, and materials than replacement. Replacing entire concrete sidewalk slabs means hiring a crew to break it up, remove it, set the foundation, and repour the concrete. This means you get stuck paying for quite a bit of material and hours of labor across a team of professionals. Find a local concrete repair specialist ». Concrete sidewalk leveling involves floating the slab up in small increments, which allows a controlled lift and provides the best protection for the concrete.
This is best handled by experienced professionals that understand the right mix of materials and equipment to use in order to protect the integrity of the concrete without any damage to nearby structures.
Here at A-1, our concrete sidewalk leveling process has been refined to a science. We drill a series of 1-inch diameter holes through the slab and hydraulically pump a limestone-based slurry beneath the slab. This material flows into all the voided areas and reestablishes the subsurface, effectively creating a new, stable sub-base.
Once any void is filled, our professional technicians slowly, and precisely raise the slab back into place. The concrete can be used immediately after the job is done. Not only do we provide a level concrete surface, but we also stabilize the base under the slab.
Take a look at these examples below to get a sense for how our concrete leveling process works, and the results you can expect.
