I need to fill an area, 50x70 raised 3' then put a 6" concrete floor measuring 40x60 on top of it. Must be atleast 3' per town code.

Crushed stone... What type of crushed stone, and how much will I need? Yards + tonnage

I always used 3/4" Gray, crushed stone. I've seen it called a bunch of different names.

And there's tons of calculators on the web to give you the "how much".

Also, I assume you're having it delivered, they'll tell you how much you need too.

Do you need to raise it 3' first? Or it is already raised?

If so, can't you raise it with compared backfill?

It needs to be raised 3' above surrounding grade. Pesky flood plain stuff :whistling

I thought about clay, and other things such as hard fill, but that can get ugly... So I figured 3' of stone would also make my 6" pad stronger...

I know there's calculators online, but, I don't know whack stone size I should go with...

Are you going to have a compaction test?

We use rock called 3/4- out here. Lots of fines.

Pretty easy to hit 95%.

400 yards +/-

Tonnage can vary depends how wet it is.

I would find out what's local. Around here granite gravel seems to be the fill of choice, when I was 200 miles north I had never seen it except for landscaping pathways.

Just shy of 400 cy like griz said. I get just under 800 ton of crushed stone, road base what ever you call it in your area. Stone could get pretty expensive just to run fill.

Find a close dirt job and see if they are heavy. They might load it and haul if you just pay the trucking?
