Rebars at pool slabs
Rebars at pool slabs
(OP)
Does ACI or any code require that rebars at pool slabs/walls should be epoxy coated? Would appreciate your inputs.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Rebars at pool slabs
ACI does not require or prohibit epoxy-coated bar for any use, and I have not seen a swimming pool specific guide or code. In structures, we mitigate chloride exposure by increasing cover depth and assuring proper mix quality; look through ACI 318 Chapter 4 and glance at Tables 4.2.1 and 4.3.1. It is also acceptable to use epoxy-coated bar to reduce any future corrosion.
Durability also depends on how the concrete is delivered, formed and finished. In order to act as an effective barrier, the concrete cover needs to be dense. The interior pool finish layer also provides a barrier to chloride penetration, and each layer of resistance adds to the time before corrosion initiates.
For elevated pools, I usually see a membrane between the structure and the concrete layer which forms the interior shape of the pool. This should protect the structural concrete from moisture and chlorides.
