Where is the wiring and plumbing?
After the panels have been secured to the slab/footer and to each other, we spray paint color-coded lines for plumbing and wiring channels. We then use a propane torch to melt back a shallow channel in the EPS foam, under the mesh. Conduit (or Pex pipe) is then fished through the channels and secured to the foam. The shotcrete is then applied and the plumbing and wiring is entombed in concrete. The wiring, being in conduit, can be changed or expanded as needed.
