Yet another 2-post concrete anchor question

[AdmiralSenn]

Sorry if this is a duplicate - I did some searching but didn't quite get my question answered.

I am exploring acquiring a MaxJax for my garage. I live in a rented house so this is subject to the approval of the landlords. They are receptive to the idea but I need to offer some assurances regarding the condition of the floor when I leave. I have offered to pay for and/or personally execute any refinishing or repair needed but I'd like some more info to help convince them.

Is there a particular type of anchor you would recommend that would allow for relatively straightforward removal/concealment in the future? I have told the landlords that the plan would be to hammer the anchors below the surface and thin pour concrete and/or epoxy to fill the holes before repainting or refinishing.

I'm assuming that there's no such thing as a removable anchor that's also safe enough to hold a lift, so I guess I also want to know if, say, epoxy anchors would make the floor recovery process significantly more difficult, for example.

I did find a few threads regarding drilling out or cutting out the anchors with torches but this seems to be a hit or miss option.

Would appreciate any info you guys can share. I'm still in the early process of planning this (haven't even measured my slab thickness yet) so any knowledge is good knowledge.

Thanks!

Just use the mechanical non-epoxy anchors. When you drill the holes make sure to go completely through the concrete. When you remove the lift, pound the anchors through the concrete and fill the holes. Fairly straight forward and easy.

^^^THIS^^^ You always want to drill thru. If an anchor ever screws up during installation you can pound it thru into the gravel beneath and try a new one. In your case, it removes the anchor from the concrete to provide enough depth to properly add hydraulic cement or non-shrinking high strength grout.

Clean the holes with water and a round brush or rag to aid in bonding.

Drill a test hole before you purchase the lift to determine how thick the concrete is.

Use Powers wedge bolts.
