The use of a concrete backer rod is recommended for filling concrete cracks wider than 1/4-inch since these cracks are usually deep. The backer rod is inserted into the crack to minimize the amount of filler needed and make for a more uniform repair. However, if cracks are 1/2-inch or larger, consult a professional about how to repair cracked concrete …
