How much additional height will this solution add from the top of the slab to the bottom of the finished floor?

The slab heating cable sits in the middle of concrete pour. Here are the layers for this application from bottom to top:

  • 8-10" of compressed crushed rock aggregate
  • 2" polystyrene insulation
  • 2 - 3" layer of concrete
  • Rebar and/or reinforcing mesh
  • Attach slab heating cable to rebar/mesh
  • Final layer: 2-3" or concrete as final flooring surface
