Yeeeeah. So I picked up a jumping jack compactor. I found out I'm not as young n tough as I was. Going to load that baby right back up n bring it back.
I had a rubber tired backhoe and built a pad. The NW corner has 30" of fill. Glacier silt with rocks mostly some sand. The SE corner is excavated in 6" or so. Sand base, undisturbed compaction. SW corner has 12" fill, NE corner has 12" fill.
I have 10 yards of D1 on site. Plan on using it to level everything out. 2" deep minimum cap. I can use the plate compactor for a D1. And going to rent a ride on wheeled compactor. Smaller sized but should compact everything pretty good. I've compacted roads before. Turn the vibrator off just before you change directions so you don't dig a hole. You can move a little dirt around too.
I'm too torn up for the beat your body jumping jack compactor. And need the compaction capabilities of a heavier machine. I'll run a sprinkler on it for a couple days to make sure I have a base that will set up. The glacial silt will bind up tight.
Eventually it will be 28x40. Outer perimeter of slab will be 20" deep x24" wide. 3" in the field. Need to be 4" above grade n 14" below grade minimum 18". I'm adding another 2" to the thickness for additional strength. 4 bars of 5/8" rebar. Under the 3" thick slab will be 2ea 2" blueboard for 4" total making it R-20. Then 2" D1. Outer perimeter has 2" blueboard on it. 4" thick on the corners. Then a 2" blueboard laying flat, 1/4 bubble actually, from the edge of the cement 4' out.
In floor heating tubing will be stapled to the blueboard. Concrete reinforcement wire sheets will be in the center of the 3" of cement.
I usually don't have my compactor on site but will try n take some pictures today.
Hey,,Thanks again, really appreciate it. I'll, we'll, work it through.
Forward man always moving forward
