Concrete foundation questions

[Sean]

Seems like most of the building areas/houses I've seen in HPP have have been ripped by the dozer. Not saying the entire lot, but at least the house pad. A contractor and I were discussing this and he told me that those volleyball sized pieces of lava are typically not compacted any more than what you get from the dozer running over them. That seemed pretty surprising to me. From an engineering viewpoint that doesn't count as compaction, just compression, and if it was just crushing big rock into little rock I'd call it consolidation. Proper compaction requires different sizes to fill all of the voids, proper material, proper moisture content and someone who knows what they are doing.

I can hear a hollow sound and a vibration in the posts supporting the roof on my patio that shouldn't be there, but I guess if it's the way it's done, then it's the way it's done...
