Self leveling and 2 post lift

[sampwell]

Hello everyone
Im not very good in english but i will do my best to explain my problem

I have a floor but it not have a good slope, 2 spot on the floor i have stagnant water, dont go to the drain.
maybe like 1/2" and 3/4" too low.

Someone tell me it VERY hard to remove 3/4" on concrete and recommend me too add selfleveling compound where the water is stagant.

But, i will install a 2 post lift 10 000lbs or 12 000lbs exactly where the stagnant water is.
Can i install the 2 post lift on a leveling compound ?

Thanks

I would probably want to place on thick metal shims so it is bearing down on the floor securely, then bring the floor up to what is desired.

I would also run this question by the lift manufacturer to see what they recommend.

Welcome to the GJ forum!

Lift manufacturers usually specify a minimum concrete thickness for lifts. Most garages do not have a thick enough concrete floor to meet the requirements, so people end up removing an area of concrete where the posts will go and pour the required depth of concrete. Do you know the required thickness for the lift you plan to install and the thickness of the floor that is there?

Any lift that you install will need shimming. Those shims generally come with the lift (just little discs of metal) so you might be able to just shim it depending on how deep the depression is.
If you're installing it yourself make sure you have the required PSI concrete and thickness.

My Bendpak requires 4 1/2" and I had that in my residential garage. But depending on where you are in the world that might vary.

Also you'll need space away from the wall (nearest end point of concrete) to install your lift.

I have 6 to 7 inch of concrete at 4600 psi with 5/8 rebar and wiremesh

It juste because the lift will where the concrete is just little too low like 1/2 inch and the water stay there.
i want to add material on the concrete for the water go to the drain.

but the 2 post will be installed at this place. just want sure if i add selfleveling stuff its safe for the lift.

but i like the idea of mike93lx, maybe cut steel same form of the base the thickness i need

I would prefer to raise the concrete at the low spots. I am thinking that water will keep accumulating there so your lift post, and more importantly the fasteners, will get wet. Eventually they will rust. My only question is whether self leveling compound is strong enough. I know it won't be stressed but will it crush? Self leveling compound is usually used to level a floor which will be covered w/ carpet, tile, or some type of flooring so there is no real load on it. I would find a couple of brands of the compound available locally and call the manufacturer.
