Smoothing stucco over Neopor
Mark and Mike from Massey Masonry apply stucco to our foundation exterior. The stucco is specially formulated to adhere to EPS foam insulation.
Attaching Neopor insulation blocks to the foundation exterior
Neopor insulation blocks are fitted and screwed onto furring strips. After the attachment , gaps will be filled with expanding foam insulation. The application of these blocks will complete the envelope of insulation running under the slab and footing, then up the exterior of the poured concrete foundation. The foundation and slab are completely insulated from ground contact and thermal bridging.

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.

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.
Order of backfill around the foundation
Course stone over the footing drain, followed by landscape fabric and gravel.
Poking out from under
These five conduits extend under the footing and emerge in the utility room. Going under the footing avoids piercing the wall. This is where we will run TV, telephone and electrical service.
