there's a hole in my basement floor!!! *pics*
I recently posted about an unknown source of water in my basement. Today, my husband got home from work, and we decided to pull back the carpet to see if we could find the source.
We peeled the carpet back, and low and behold, there's a hole in my floor!
It's does not look like a drain hole. It's only about 1.5 inches in diameter. It has rough edges, and the edges have been painted basement floor grey, along with the rest of the basement floor.
When we shine a flashlight in there, we see foundation ants and sand. The sand is wet. There is a dark stain
The hole scares the crap out of me, because there is no fathomable reason for it to be there. It's close to an inside wall, and it's in a high point of the floor. I'm wondering if this is the source of my water problem that I experienced this past weekend.
Any ideas what this hole might be, and what it might be for?
Here are some pictures. I apologize if they are overly large, I just didn't want to loose any detail.
There is a quarter in some of them, for size reference.
The hole, and it's location against an inside wall. Do you think the discoloration on the floor is an indication of water coming up from the hole previously, and running alongside the bar?
The hole again. Notice on the underlay off to the side, how there is the brown stain? That is sand. I'm guessing that's a good indication that water has come up through that hole before?
The creepy inhabitants of the mysterious hole.
This tile is beside and behind the bar you saw in the first picture. Notice how the concrete is notched where the carpet trim is attached to the floor. The tiles are deformed in a sort of ridged pattern, lining up with those notches. Also, you can see the efflorescence on the tiles. The mystery for me here is, did the water really come up from the hole, and work it's way across the floor, under the tile, evaporate, leaving efflorescence?
Please...tell me your thoughts on this mystery! Any idea why there would be a hole like this placed randomly in the floor? Do you think this is where the water originated from??
