After the sidewalk has been evaluated, it is important to determine the cause of your sidewalk problems so that an appropriate repair plan can be implemented. Rather than simply cutting out and replacing each location, examine the situation on an individual basis. It simply does not make sense to approach your sidewalks with a single replacement repair method. Today there is a wide variety of sidewalk repair technologies available, that when implemented correctly, can result in major savings of both time and money. There are three primary repair methods, each having their own distinct advantages and limitations.
Concrete replacement is the traditional method used to repair sidewalks.
Concrete replacement involves cutting, removing and repouring the concrete. However, it is very costly and can usually be avoided in most situations. Concrete raising is another repair method. It lifts the slab back to its original position by pumping material under the sidewalk through drilled holes in the slab. Although it is less costly than replacement, it is only effective on sunken sidewalks, and it is not offered in many areas.
