My shop is in the basement of a old building and we never had a problem with it till they screwed up the drain line when they installed the light rail. not sure why it flooded tonight besides the very heavy rains we had for a bit. The floor is not flat and it seems my shop is on the high side and I only have a little bit of material with wet bottoms. I had dropped my shop insurance when I was so slow I could not afford it or house insurance. got the house insurance back so now I can't put off the shop insurance. Sorry about the pics it is fairly dark in there. my shop is clear in back and the water did not quite make it to the door.
