Yesterday was very mild all day. The forecast said rain and the clouds agreed but it never actually rained until about 3 this morning, when it rained real good and now I’m dealing with mud again. Anyway…
Yesterday morning I had breakfast with S&L, and I took that opportunity…

…to do something I’ve been putting off all winter. I borrowed S’s jackhammer again.
Ever since last September I’ve been dealing with wet concrete on the south-ish side of Ian’s slab. It’s not caused by any problem in the water system, and given that last summer’s long soaky Monsoon popped a number of new springs here and there I am forced to conclude that that’s what’s going on here. It might go away by itself in the fullness of time, but Uncle Murphy says that’s not the way to bet. In the meantime…

It’s causing difficulty. So I asked Ian for permission to hammer a small hole in his floor in an out-of-the-way spot behind the bathroom door…

… to test the feasibility of installing a sump pump. Yesterday, after much procrastination, was the day.
I know I can install the sump without much difficulty but I had real misgivings about how hard it would be to make a big enough hole in the slab all the way down to dirt. I couldn’t remember how much reinforcement the slab had but I knew there was some. And we all know how much fun Murphy likes to have with that sort of thing.
But in the end…

…it was no trouble at all. I had a fist-size hole down to dirt in less than half an hour. Turns out jackhammers are a lot easier to work with when gravity is being your friend.
Now: The outcome of all this that I was hoping for was that the hole would fill with water overnight, or at least get good and wet. That would indicate a condition that a sump pump could actually help with.
Unfortunately…

…that’s not what happened. The sand under the slab is damp, certainly, but it was damp yesterday. It’s no wetter now than it was then.
I’m going to check it every morning for a week, and if the situation doesn’t change I’m going to have to conclude that the answer is No. And then I’ll fill the hole with cement and live with a wet slab, because a sump pump is the only possible solution to the problem I’ve been able to come up with.
