The stem wall was successfully poured and stripped of formwork. Work started immediately on preparing the high mass storage area today. 2" of Dow Blueboard extruded polystyrene rigid insulation is shown being placed on top of bedrock in the following photos to insulate the storage area. Footing and stem wall will also be insulated in a similar manner.
I arrived from San Francisco for a site visit today to review details with Todd and meet with Terry, our concrete subcontractor, to review and approve the most effective strategy for minimizing and controlling cracking in the honed and stained concrete slab, which will be our finished floor.
The stem wall was poured with a 20% fly ash content.
Two inches of soil from our excavation pile is sprayed with water and compacted on top of bedrock to create a smooth and stable surface for the placement of insulation. The compaction process is shown in the video, below.
