Pouring New Sidewalk over Existing Sidewalk
Pouring New Sidewalk over Existing Sidewalk
(OP)
I have a project where a contractor wants to pour new sidewalk over the existing. The existing is in fairly bad shape. He wants to place a layer of sand between the two. My idea was to make him put an epoxy coating over the existing sidewalk to keep the two layers from bonding to each other. Any ideas?

Concerning the proposed epoxy coating, placing new concrete directly on old concrete that is in poor condition is asking for trouble - whether the layes are bonded or unbonded.
