It's underground. There is one wall crack that was blackjacked and hasn't caused an issue since 2007-08 when we had two 50-year floods in a row. Last August's IL hurricane/derecho cracked my basement floor from wall-to-wall, like a spider web. The middle of the floor is humped up. Last night I swept water south toward the lowest spot, the main floor drain, the water kept flowing back at me, to the north and east. Rusty clumps of gunk came up through the floor drain last summer. I paid Roto-Rooter $200, he cleaned the main drain and the one coming from the washing machine, one-year warranty. He had to come back a week ago. I need an engineer or home inspector, concrete fixer came to look but it's not his gig. It was the storm. I have city storm sewer running through my property, literally, it goes under my deck and then to a manhole cover, that goes down 62 feet into my ravine to drain. I don't think it's draining right, been begging for them to check it. Two years after I moved here the city street crew spent two days cleaning that out, 35 years ago. They had to lower an end loader/back hoe? down via a towing company's winch to clear it out at the bottom so it'd drain. In June 2010 a derecho took down 100+ trees in my ravine, I think it might be blocked again, but I'm just a girl, right?
