We wanted to have a heat storing solid floor so we opt for a 6" slab poured on 4" of closed cell foam. Prior to pouring, the 1" hydrant and 1 1/2"conduit were hand dug and placed. Drainage is directed to the bricked area with a 1"x4' slope to center from the walls. The bricked area, while ascetically pleasing also allows for access to service or replace utilities. The concrete was cured 30 days,etched, stained, and sealed.
We did not use the provided 4" steel channel for the base but rather used ripped composite decking to mount the walls directly to the concrete with Tapcon screws, sill foam was placed under the composite and the aluminum was chalked to it. The channel fasteners were modified to be screwed to the composite also.
