17,000 dryer fires a year, when did you last clean the inside of the dryer near motor or the exhaust ducting?

That's an interesting article Gary.
Short answer.......don't place sand on top of the poly barrier before you place the concrete floor.
6 mil poly and then place the concrete..........that's it.
That article also talks about what many of us in concrete already know........that concrete acts like a sponge when exposed to moisture.
And check out the part about bricks being used on the outside of a home.........that is an eye opener.
Brick's act like concrete when it comes to moisture, but what's really interesting is when the bricks get wet and then the sun comes out and warms up those bricks........and what happens to that moisture.

Big thanks to everyone who answered!!!
hitting some of the points that need directly answered.
Size - approx 800 sq ft garage/workshop, 600 sq ft creative space, 600 sq ft living space, so 2000 sq ft total.
Material - I was thinking PVC, I know it may look messier, but it will probably seal better/easier. I am interested to hear your thoughts about materials though. Does anyone have strong feelings as to why one material may be better than the other. The only thing I know for sure is that it will be a plastic.
So, just to summarize, and see if I got it right this time.
1 - dig a big hole
2 - build the forms
3 - mark out where all the supply/dwv piping needs to go, and trench that out (how deep for this trench?)
4 - Lay a gravel bed in the piping trenches
5 - Install the pipe
6 - Have the local building inspector come out to witness the testing of the pipe (is this necessary? will they test supply and drainage?)
7 - Back fill the trenches (gravel? soil? mix?)
8 - Backfill rest of foundation with gravel
9 - Compact gravel
10 - Add vapor barrier
11 - Add rebar
12 - Place concrete.
13 - Install perimeter J bolts.
So am I somewhere close this time? or do we need to tear it apart again?
I appreciate all the help, I feel I have a better understanding already, but we might not quite be there yet...
