The Foundation

Step 1: Several concrete pillars were sunk to bedrock to provide a firm and stable footing for the house.
Step 2: The dirt between the pillars was replaced with a concrete/gravel/sand/dirt mix to provide lateral stability.
Step 3: A flat slab of concrete was poured on top of the pillars and will serve as the platform for the house as well as the sub-floor.
Step 4: Footers (side walls) were poured to elevate the house from the slab (and ground level).
NOTE: Extensive reinforcement bars are used since we live in an earthquake prone area (Pacific Ring of Fire) and on the sid eof a volcano (Mount Fuji)!
NOTE: You can see all the rain we have been having, and that has slowed the construction down. We have just started the Rainy Season in our area of Japan!
