I have a large workbench which I inherited with my current home, and I'd like to replace it with one I'm currently building, mainly since the current one is pretty small, and the top of the bench has a massive crack, so it wouldn't be safe to bolt down my heavier tools to it.
I've removed the bench, but there are four large floor expanding anchor bolts stuck in the concrete, and they won't budge. What is the best way to deal with them?
I've read some blog entries on other sites recommending I just pound them down into the hole if there is extra space (there is), and just patch it with some quick-set cement. My concern with this is:
- There will be gaps between the hole radius and the anchor, and if water gets in there, floor damage in the future.
- The anchor is still there, and I just cover it up, I don't want someone else in the future (new owner if I sell, contractor, etc) drilling straight down into it and facing a potential injury from hitting the anchor.
I could chisel around them and patch up a much larger, cone shaped hole I'd be creating, but I'm trying to see if there are better alternatives.
