It's almost time to pour the heated slab. Here's a footprint of the preparations for the slab. A previous post gives a nice overview of the foundation footprint.
Features include:
- A 4' perimeter of 2'' Styrofoam SM around the outside walls (light blue)
- A pantry area and storage area under the stairs which is to be unheated (dark blue)
- Manifold box (dark red)
- Compacted 1/2'' clear stone to fill the foundation
- 6 mm or thicker polyethylene vapor barrier
- 2'' Styrofoam SM
- Rebar grid to reinforce concrete and hold tubing in place
- 3 closed loop Pex tubing tied to rebar with plastic ties and attached to slab manifold
- 4'' poured concrete slab
