Oops! found an error in my diagram. The second interface should actually read:
<- interface between capillary fringe zone 1 and unsaturated zone

Please forgive the wall of text. This is really me kind of thinking out loud as I try to understand what might be going on outside my basement wall in the context of subject matter that is new to me. I appreciate folks pointing out any errors they may see in my thinking.
Oldestguy, thanks again...
So just to clarify, you are saying that if the crack at 6ft is "fine" enough to create capillary attraction (i.e. suction) greater than that of the soil then water can leak into the basement through the crack even though the water table is well below the 6ft crack level. Is that correct?
If so...
Your introduction of the term "perched" had me heading to Google. [smile] So my search introduced me to the wonderful world of hydrology and partial differential equations. Fascinating stuff! Being an EE, I especially appreciated the analogy between Darcy's Law and Ohm's Law. So I do want to get...
I understand when your fixing a problem on the job you don't have time to conduct a science experiment (time=money). As a homeowner, I don't have such constraints. :) Can I ask you to speculate? what does the spoil/groundwater science say on the matter? If the drain tile is clogged does the...
Thanks BigH. I actually might try that when I get to the solution stage. However, I'm the type of guy that likes to get a detailed understanding of the actual problem first hence my questions about how water might build up around my basement wall and how the use of a dip tube down to the footer...
My sump pit has two 4" black corrugated drain pipes entering it which I suspect form the exterior perimeter drain tile system. During heavy rains only one pipe drains water into the sump pit. I have never seen anything draining from the other pipe. I suspect it is this pipe that is supposed to...
That sounds like a much simpler and elegant solution! :)
I suspect a portion of my exterior drain tile is clogged but I was trying to get a feel for how much a working drain tile system would limit the hydrostatic pressure. I have a small leak in the corner of the north basement wall that only...
I am looking to measure the hydrostatic pressure at the outside of my homes basement walls. The basement has poured concrete walls with the north side of the basement completely below ground level but with the south basement wall above ground level with a walk-out basement door and no stairs.
I...
