A floating foundation can be safe. But not if you dig a giant hole next to it and pump out all the water. SF quietly settled and paid for most of the repairs.

Soil stability and it's ability to support a building depends a lot on water situation.
- trhway 5y ago>A floating foundation reminded - back at University i worked summers on construction mostly doing foundations in Siberia in permafrost zone. The most memorable part of the quick introduction to the profession there was when they showed us several buildings which didn't have piles deep enough - most of those you could easily spot from a distance by the building shape defects like tilting, bended roofline, etc... because if piles aren't deep enough the foundation pretty much becomes really "floating" during warm season after several cycles of freezing/thawing.
