Pool
Bond Beam
The reinforced concrete ring at the top of the pool shell that anchors coping, tile, and deck.
The bond beam is the structural collar at the top of a gunite pool. It's typically 8–12 inches thick with doubled rebar, designed to resist soil pressure pushing in and to provide a stable substrate for the waterline tile and coping. A weak bond beam telegraphs into cracked tile and lifted coping within a few years.
