I would have done a layer of 3” x 3” #8 copper bonding mesh, a layer of rebar, a layer of steel mesh and a top layer of 3” x 3” #8 silver bonding mesh with each layer connected to the bonding wire in 100 places using exothermic welding, but that’s just me, I’m sure that your bonding will be fine.Yes both the thick rectangular chicken wire-y one and rebar. Tied into the grid at my request. The patio guy said that he found it odd that it wasn't a requirement here but he also thought it was a good idea.
