Thank you gentlemen. My wireless router took a dive, and I couldn't find my book, since I don't use it much any more. Unfortunately for all of you, I'm back on- line..[:-tong2]

The house I inspected yesterday had a slab floor in the garage, with crawlspace below (wood framed structure). The slab sloped back in towards the house. (oops). I can't wait to see how they will correct this one.

Besides the garage slab floor issue, the entire roof is going to be ripped off and replaced. Bummer.

They may be able to install a drain at the back of the garage?

BTW, I'm told garage floor drains are the only way to go out on the prairies. Prevents the door from freezing to the slab.
