I have anchor rods to support sidewalk in the condominium building I live in. They were found to not be sealed on one of the sides of the building. We had poor drainage on one side and seepage occurred from the location of only the holes for the rods. Had it dug up on that side, holes for rods found not to be sealed. Should the remaining sidewalk rods be dug up cut off and sealed as advised by the contractor we hired. Anchor rods are below sidewalk level and support from underneath.
