I have a two post car lift to install in my shop, obviously the posts need to be perfectly vertical. The problem is, the entire floor slopes toward the center floor drain.
The base of the posts are 24" square, the floor drops about .25" over that distance, where the lift will be mounted.
My three idea's for a fix so far are...
1. A tapered shim under the base.
I want the base to be fully supported, so the shim or shims would have to be quite large. I have not come up with a reasonable way to produce such a shim yet.
2. Build a form and pour some type of harding filler where the base sits.
I don't know what, if any material would strong enough to do the job at less than .25" thick.
3. Using a masonry wheel, grind the concrete level under the base.
This is the method I am leaning toward now, but I don't like the idea of making the floor thinner under the base.
Any and all thoughts or suggestions on how to accomplish this, are appreciated.
