Radix 2: Thanks for helping me clarify the error in construction.
Dr Stan: Thanks for the advice. If I understand you have set your garage up like a basement with the sump pump. I may have to go that route someday. I believe I am going to dig it down to bottom of slab/footer (God only knows what they put in), clean it and use some form of waterproofing, likely a combination of Drylok, roof cement (tar) poly and 1/4" styrofoam to above grade with a piece of flashing in a z configuration set in place with Sonolastic sealant. After this, I will have need to get the water away, probably via a French drain, but it will have to go about 50' across the minefield known as a water maple's root system. Still cannot go back and put a poly barrier under the slab which would stop the hydrostatic pressure from pushing vapor into the building.
OP: Sorry to have hijacked your thread.
