Is driveway leveling a long-term solution? 

Yes, driveway leveling, especially when done with polyurethane injection, is a long-term solution to uneven concrete. This method not only raises and levels the concrete but also stabilizes the soil beneath, reducing the likelihood of future settling. However, the longevity of the repair can also depend on addressing the underlying issues that caused the unevenness, such as improving drainage around the driveway.
