   I have a 15'x20'one and a half car garage.I'm making
   it into a small woodshop.I would like to put a plywood floor over the existing concrete pad that the building rests on.The building & pad are 25 yrs. old.The building is on my property behind my house which I just purchased 3 months ago.There is a 3/8" crack in the middle of the pad going from side to side.The pad slopes from right to left from zero on the right to as much as about 4" to 6" along the left wall with the lowest point where the crack meets the left wall.The previous owners (of 22 yrs.) recall there being some slope to the pad as well as the crack.The property looks as though there was fill put in at one point and the garage is on top of it.I would imagine that they didn't compact the soil before pouring the pad nor did they put proper drainage beneath---which I see no evidence of. The previous owners had the sill replaced 10 yrs. ago,they used P.T.6x6.They jacked the building up & formed up an 8" wide concrete foundation on the existing pad perimeter.This foundation goes from zero at one point on the right wall up to 6"+ on the left wall to compensate for the slope I talked about earlier.It seems the right thing to do would be to move the building and start over with a new pad w/ proper drainage and compacted soil but I can't afford that right now. My questions are;
   Can I pour a level concrete floor on top of what exists?
   What kind of concrete would be best?
   Should I just scribe floor joists to what exists?

   The head room now from the highest point of the concrete pad to the bottom of the ceiling joists is 8'.I'd like to save as much head room as possible.
