Hi everyone --
My shop is an old shed from around 1870 or so, and it's resting on concrete over stone. The concrete is not too thick, has developed cracks, and they are large enough to complicate moving equipment.
About a decade ago, I cleared out one of the wider sections and filled it in with new concrete, though I'm no mason. I could do that for the wider one pictured below, but for the narrower crack, there's nothing to really clean out (except sawdust). I thought of epoxy, but I don't think that will work, as it would just seep into the crack and fall to the stones underneath.
Please let me know your thoughts.
Thanks,
Ned
