Site overview on foam installation day.
The foam is brilliant white from the clear sun, making it hard to see inside the foundation.
Hand saw through 5 3/8″ EPS.
Fitting the 5 3/8″ x 4′ x16′ blocks.
South end corner foam installation detail.
The revealed square of concrete will be filled up to level with the top slab concrete pour. It will support a structural column inside the house.
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.
Course stone over the footing drain, followed by landscape fabric and gravel.
Strong winds overnight blew our neatly stacked EPS foam all over the field.
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.
This is the first opportunity to get a sense of inside space in our new house. This view is looking South to the lower level sliding door entrance. The ground beyond will be excavated out after the completion of the foundation.
Dan and Rich install rebar for the inside of the lower level 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.
The footing and South end frost wall have been brought up to level, ready for the foundation walls.
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.
