Is It Better to Repair or Replace Uneven Concrete? 

Sometimes it seems easier to address the problem with your driveway by removing the slab entirely and installing a new one. This is sometimes the only option when the harm is irreparable. However, this is not always the case with your concrete driveway and sidewalk, and the appropriate fix can often do the trick. Additionally, the expense of rebuilding the concrete can be considerable. It depends on the size of the driveway and the underlying cause of the sinking in the first place. Unlike replacement, repairs address the underlying source of the problem and correct it.
