Structural fill required?

[farmerjohn1324]

I was doing some research on using fill for house pads. Apparently, it's always best to pour foundations on undisturbed soil. In this case, I have to bring in fill. I need over 3 feet depth of fill.


I read that I should compact it every 6-10".


I also read that I should use something called "structural fill" which is specifically designed for this purpose. I read that coal ash (fly ash) is the best type of structural fill to use.


The foundation is going to be 46'8" x 88'.


What do you think of this?

This is just east of Orlando, FL.

You are going to have to have a permit for the slab and plumbing, so you'll also have to prove the compaction, and unless you are also a licensed compaction contractor, YELLOW PAGES.
