Have not been able to reliably dry the basement in 22 years. The basement needs to be dry. So I have started an interior perimeter drain.
Yeah, there are things that need to be done outside, but they have never been reliable before. No reason to believe outside work alone would work in the future (that definition of insanity thingy) so I'm doing the inside first because the basement needs to be habitable and the outside stuff will be done later.
The house is poorly located on the lot. It sits only a foot above the lowest point in the yard with most of the yard higher. The low side of the yard is on the side that only has three feet to the property line and pushing water away from that side just puts it in my neighbor's basement. I suspect he might have issues with that. There are big concrete steps on the front, paved driveway and carport on one side, concrete patio and basement steps on the back and three feet of property on the other side. Digging six-seven feet down to the footing outside is not going to happen.
The starting point is the sump I put in 20+ years ago. So far I've gotten about 20-25 feet dug out of 120 total planned. Since we measure droughts in hours this year, the trenches have already been tested and I'm comfortable that this path may actually work. The trench might be bigger, but I am intentionally keeping it smaller to reduce the stuff that has to be hauled out and material that has to be dragged in. The trench is lined with landscaping cloth in addition to the sock around the drain pipe to reduce silting of the trench itself because I noticed that the gravel bed around the sump has silted up solid.
Question: What is a cheap way to get water from behind the water proof membrane on the wall into the drain tile under the floor? Cheap is the operative word. Dimple membrane would be nice, but my heart (and money... but mostly my money) belongs to others. So I'm thinking 1) 6 mil sheet hung from the wall, 2)... 3) water goes into drain tile. Then build a frame wall over the sheet.
Second item: I've seen a number of posts about building a 4" frame wall offset 4" from the concrete foundation wall. That sounds like a lot and I don't want to do all this and end up with a basement closet. Old walls in my basement have aged badly because of the persistent water issues. So my plan was to use all treated lumber, ROXUL mineral wool insulation, blue board and maybe even cement fiberboard for the lower foot or two of the wall because I have to assume that no matter what I do, it will get wet again. Note that the planned use is utilitarian, not finely decorated.
