Fill it with concrete and you've got a poor mans bollard
And hammer at least one piece of rebar down through the bottom. Without the rebar, if you hit the post hard enough, the concrete will crack, and then you’ve got nothing more than the PVC pipe anyway. A piece of rebar down the center will greatly improve the strength of the whole thing. Having said that, if you’ve got a piece of steel pipe or conduit or something, you could save the price of the rebar, it just won’t last as long.
PVC will get brittle and fall apart when exposed to sunlight anyway.
Do you have any short pieces of 2 inch left over? Technically, you should not have any exposed romex inside the building, especially a garage. You could run a short piece of 2 inch from the panel up through the ceiling and try to fish those wires through it. Or 2 pieces of conduit. Problem is, your panel probably only has one large knock out in the top middle.Seems crazy to fill this hole in with concrete when the concrete around it is so screwed up, but I just don't have the money to rip up the concrete around it this close to Christmas.
This whole corner is kind of sunken down. I wanted to make it level with the rest of the concrete, but then it would have stuck up to high.
Maybe I'll dig up the other broken sections next year. Reminds me of a highway job where they cut up and repair the bad sections before pouring a new road surface over it.
The concrete's only 2-3 inches thick. I dug that hole 18-inches down and left an 8-inch space between the top of the stump and the bottom of the old concrete. I put in a layer of broken concrete at the bottom, then gravel, and then topped it with 4-inches of concrete. The bags of concrete that went in that hole weighed more than I do.
I guess I should start hooking these wires up.
