Apologies in advance - I'm sure this has been asked & asked, but 2800+ hits on basement and roof is a bit overwhelming.
Old house, roof needs replacement - tabs coming off during high winds, hope to do this this fall after refi.
Wet spring (2nd wettest on record for area) and first time for water in basement. Gutters kinda clogged with roof material, so cleaned out. No rain since, unfortunately.
Possible that gutters drain into cistern next to house - brick and mortar walls, lid caved in during rainy spring. Have replaced one downspout (3 total on house) with a pvc tube that directs gutter output well away from house, 20ft or so into yard. 2nd has drain pipe on it, again directing well away from house, maybe 12 ft. 3rd might drain to cistern, I don't know for sure.
Water in basement seeping in from odd corners, flowing across floor to drain. Has to go through whole basement to get to drain. 2 areas definately coming from below. Basement is poured cement, several cracks around perimeter that could go through or not (never had water in basement except what came in through windows via high winds).
Been here ~9+ years. So about the cistern. I am pumping it dry (well away from house) then in the evening, I can pump again for 1.5-2 hours. I've checked, and it seems to NOT be a leak from our well - the pump doesn't run constantly, have turned water off and pressure tank stayed pressurized. Ground around house slopes ok, except gaping hole where cistern is.
What are the chances the roof is causing this problem?? I see dampness on the exterior basement wall just under (beneath, lower than) the siding but not from siding to ground, just up on the wall a bit - I have no idea what this is, where it is coming from. There is some efflorescence on one wall in basement, that has been there a while.
I need to get this sorted out because I think I'm gonna start to have problems if it doesn't dry out down there. Am running a dehumidifier to drain. It has dried out once (constant pumping cistern AM and PM until dry) but after our last rain a couple weeks ago, it's been wet again.
Water is seepage, less than 1/4 inch deep, but it is wet enough to splash in.
Need some guidance please! Sorry for long post, trying to get all nec. info included.
Thanks.
