This is a slightly different building product. There is no foundation, as the supports are sleaved with plastic post protectors. The posts are between 2 and 3 feet in the ground. After the building is built, they pump the cement into the building, and it gets poured around the posts. It actually is a stronger system, and much more resistant to strong winds (i.e. we have hurricanes here). You should sww the cement coming in about a month.
