That's really funny. I've been getting ready to get some bids for the
front
of my shop. It will be just like yours except for the drain. Right down to
the old foundation in the way and sloping the grade.
Today I find out our big forklift threw a rod, see my glote post. With a
new forklift, a pad and a level lot...loading trucks won't be such a PIA!
ANOTHER problem permanently solved, only a few thousand more to go.
Good luck with your job!
