Wet basement & foundation problems
First post here....I am going to try and provide as much info as I can so please bear with me.
Basically, I have a pretty bad water issue in my basement. We have an inside perminter wall drain system with 2 sump pumps that can handle a lot of the water problem, but for especially torrential rains this just does not cut it and I want to do more to fix the issue. This AM I found a few new cracks/holes in the foundation wall, water streaming out. This is along the wall where the drain system is not up against the wall itself because of part of the footer is exposed and they could not jackhammer into that of course. We also have what looks to be a double-wall foundation along a couple sides of basement, and there was water gushing through the slot created between these 2 wall structures...never saw this nearly so bad before. There are other random spots in the basement where there are leaky walls or wet spots on the floor seemingly from water coming up thru cracks in the concrete floor.
I am dealing with an almost 100 year old bungalow located at what is mostly the lowpoint on the street-- the backyard and next door neighbors are on higher ground. We get a LOT of rushing water (like a stream actually) through the yard that then goes along the property line with the other neighbor and then out to the street. I should mention another part of our fix will be to create a channel in the yard to help make the water flow more uniformly out of our yard and into the street.
We have downspouts that go away from the house and there does not appear to be an issue with the slope of the land next to the house. It seems the next step is to do something to the exterior of the house to address the water issues. Since this water issue deals with the foundation, it got me thinking about other issues we have.
I want to try and do everything that may be wrong at the same time, meaning figuring out whether our not-level areas of the house (also seems to be worse on this side of the house where almost all of the water action happens) can be fixed at the same time we are digging around the house to prevent the water from getting into the basement. Is this possible and what could/should we do? Thanks for taking the time to read!
