diy stand on concrete floor with hump

I wrestle with this concept myself. My research has told me that a floor leveler can be used, but how they work and if they work on concrete i have no idea because I never went that route. I always used composite shims making sure they are placed directly under any structural supports of the stand, your "beams" going up and down. Always wondered how all the weight sitting on ships is affecting things. If I were in the position you are, get a bag of powder concrete or tile Thinset or whatever the compound is called (your hardware store will help you with what's best, sorry don't have a name for you just a concept) mix it in a bucket, apply where you need it to with a trowel, and when it dries you may need to do it once or twice more. I wish I had that luxury, i feel like that would be a really easy job, once floors are down it becomes harder. Good luck, leveling is important in the long run.

I'm no mason but from what I've read self leveling concrete is pretty difficult to work with.

I'd probably go with a stand with legs versus something with solid runners on the bottom and shim it appropriately.

I'd doubt the concrete would shift. I mean it's always a possibility in any basement especially if your in the north, but I wouldn't worry much about it

I shimmed a stand on an uneven cement basement floor. I used a steel rack with 4 legs and shimmed the feet with cut up pieces of 1/16" of flat metal stock. I was going to use wood shims, but I'm glad I used something more robust, and impervious to water

what i have done is lay cinder blocks down, build your frame, brace though out, 3\4 plywood on top. after you have this. you can level it using whatever, i used 2x4. then you can hold a board on one side and trace where the two boards meet. this is your cut line. sorry all i have is a video. but if you look at the stands of my tanks. you should be able to see. https://www.youtube.com/watch?v=w6-EGB--HKc

I'm thinking about pouring a pad on top of the floor. Maybe some rebar and mesh will keep the crack from transferring into the pad. I just did a concrete bar top so I have a bunch of forms and tools leftover.

Likely this is easier and much cheaper than self levelling. Giant pain in the behind to work with, especially for such a small job.

yes
