looks like some more detail is needed. It took 90 days to rehab, it's been over 180 days and a wall has wept 2x, but not enough to flow to a floor drain, and there is not mold present nor does the wall remain damp, so yes I would call it minor.
1. The soil is already graded out with no pooling at the foundation. It all pitches to the far side of the driveway, 14 feet away, where a french drain is installed running to the street. (I did have a friend who is a waterproofer look at it the time I witnessed the outside flood, and saw water inside, and he indicated installing a sump may not flow enough and also allow an easy spot for penetration)
2. There are gutters on a 24" overhang, and the driveway is 18" from the foundation. No water falls from the roof, and all of the drain tiles function.
3. I do not know how often the river overflows but both instances were over 3" in 1 hour (100yr flood amount), beyond capacity of the city storm system, and closed a few intersections in the neoghborhood.
4. The last time it rained there was a yard debris line present about 1 ft from the foundation on the low side ( drive is on the high side, about 2 ft of fall across property) this line is above where the storm water exits. So what I am saying it that the subsoil is super-saturated.
5. The basement wall is exposed block which is painted only. I don't know if Drylok would bond with a preexisting coat of paint on it. There is electric and a paneled center wall creating division from laundry and bathroom down there.
And to my original question, MANY landlords have some form of moisture, so what are they telling tenants, and what are they responsible for?
OBVIOUSLY, a french drain inside or outside isn't happening this week, or probably not until I turn the unit over to a new tenant. The area could be used as a playroom/poker room but wasn't marketed as such. In the mean time, do I tell them to use a mop and don't put valuables there? Refund some rent for the inconvenience? Tell him if he sees mold to contact me to remediate? Move them out and rip up the foundation on a hope it fixes the issue?
