A number of swimming pool builders in New Jersey are struggling with the grid requirement needed 3 feet beyond pool wall. On concrete pools one can extend the rebar out 3 ft before deck is installed. On inground vinyl liner pools, pavers are often used and it is cost prohibitive to add rebar for the 3 ft surface around pool or NEC gives the other option of #8AWG. That even is more expensive. The normal welded steel wire, that is often used in decks for vinyl liner pools is not specifically listed a meeting the grid requirement. Has anybody else been struggling with the grid material for vinyl or fiberglass swimming pool?
