Saturday Ed, Charlie and Chaz helped with the backfill, with Charlie's excavator getting the bulk of the work, trenching for Power, Septic, Water and the drain pipe off the perimeter drain, and the backfill. Nice to have brother-in-laws with equipment.
Compacting the base for the slab after two mixer deliveries of 14 yards each, and another 20 yards moved by hand from outside the foundation to the interior by rake, shovel and wheelbarrow (lots of them) over five days.
A break to smile at my chief cheerleader.
One inch rigid foam installed over the stone and all the seams taped. Perpendicular to this run will be the 2 inch rigid foam stacked in the corner for R15 total. Probably overkill with R23 walls down below 3', but the radiant heat will be more responsive.
Two inch rigid foam installed but awaiting a dry period to tape all the seams. Then it's time to lay out the rebar and PEX tubing for the radiant heat.
