2 post lift on expansion cut line?

[slimcake]

So I have 6 plus inches of concrete in my floor but the way its looking is the inside of the one post is going to be on top of the expansion cut line. With two of the anchors being only 2 inches from the cut line. Do I need to worry?

I would not do it. I made sure I put my lift about 18 inches. If you have rebar in your floor, you could probably go closer to the natural crack line.

Consult the mfg. My guess is they would have you cut a pier in or plate the bottom, plate being wider for better anchoring.

Talk to the mfg, but I am going to say no.
I might say over the expansion like may be ok but the anchors 2" from the edge will be a no go.
I think you need a min of 6" from the edge

I think 2" is too close for expanding anchors but you might want to look into the epoxy anchor stuff. Iirc it let's you get closer to an edge but again, go by what the manufacturers say as your life depends on it

Be careful of this, seems too close to the edge and a crack waiting to happen. Metal support plates to spread to load and anchor them, anchor the post to the plates.
