The deck extends over the edge of the foundation, overlapping the 10″ blocks of Neopor insulation that that will attach to the foundation wall below. 
The underside of the cantilever is sealed to make the shell of the house airtight.
The underside of each beam is glued with OSI SF-450 adhesive. The bead runs along the perimeter of the connection point. The screws go through in the middle to avoid breaking the bead seal. 
The two-by-four lumber under the soffit is an attachment point for the Neopor blocks of rigid foam insulation. The blocks will be notched out to fit. All gaps will be filled with spray foam insulation.

Pouring the slab
Rain has caused delay. The slab is poured at the first opportunity of clear weather.
4” of concrete poured on 10″ of EPS foam.
Dan Gregg brought in extra hands for the slab pour.
Dan and Rich from Dan Gregg foundations.
Clearing our in-floor electrical outlet.
Slab finishing.
Edge polishing.
Dan Gregg spent the day polishing the floor. 
The finished slab with expansion joints cut in place.
The rain returned at the end of the day.
Lily testing our foam insulation
Color coding against backfill
Turquoise = spray coat waterproofing Rub-R-Wall. Dark gray = 10″ blocks of dark gray Neopor. Pink = vertical strips of pink XPS blocking the seams, board and batten style.
Blowing in the wind
Strong winds overnight blew our neatly stacked EPS foam all over the field.
Stacks of rigid foam insulation
The blocks are 10 inches thick by 14 feet long. After the foundation is sealed, the blocks will be attached to the outside of the wall from the footing up to the sill. This will complete the outside layer of insulation that completely separates the foundation from the surrounding soil. Blocks will also go under the slab. The white foam is EPS. The darker blocks are Neopor from BASF, a graphite-enhanced EPS with higher R-value.
Vapor barrier running over footing and under walls
For perfect air sealing, moisture control and maximum energy efficiency. A 10 mil plastic sheet extends from under the lower floor slab (not yet poured). The sheet passes over the footing and under the yet to be constructed wall (rebar shown in place). Outside, the sheet will help seal the foundation wall.
Frost wall is insulated and backfilled
The footing and South end frost wall have been brought up to level, ready for the foundation walls.
Applying insulation to the frost wall
Bill Stratton general contractor and crew surround the South end frost wall with rigid foam insulation. There will be complete insulation between the foundation and the surrounding soil.Waiting for the pour
