Hire An Operator
Make sure to hire an operator for digging up the foundation
This sort of foundation is done all the time. Any house with an attached garage, essentially has a hybred foundation: part slab and part crawl. What in particular are you asking about?
Of course, one problem with the scheme is that the two pieces don't move together. Not such a big problem for a garage, but can be a problem for a house.
will like to the pros and cons of this type of foundatoin. any experience working or dealing with this type of foundation. the long term reaction of this type of foundation. earth movement , foundating shifting.
the crawlspace is mostly for plumbing and hvac access.
