Patch concrete to make it level
Hi! I have some concrete around the house that is sloped to carry water away. I need a temporary fix that should last about a year, before I remodel the whole area.
What I need to do is to create a couple of areas each one about 1' x 1' that are perfectly level, so I can bolt down some posts and keep them vertical.
I think I'll need to add about one inch of concrete on the 'deepest' spot.
After cleaning carefully with a pressure washer and building a small "box" around the areas I want to level, which procedure should I follow? Can I just use regular concrete mix or should I get something special for this purpose?

I would look at concrete repair or resurfacing compounds. They are intended to work as a thin layer and to bond well to existing concrete while I think regular concrete would soon crack and break free from the old.

You don't say what kind of posts or what they will be used for. New concrete, especially that thin will not have nearly the strength as the old existing concrete. If there is any side load or vibration as in a fence post, I think it will crush and crumble. Is it possible to use an adjustable standoff or shim the bolts with washers? If you do go with concrete, I remember seeing a product called Cement All by Rapid Set at HD. Fast setting, high early strength, feather to 0". Never used it though.

I have most often seen pillars like that poured first with their footers then the slab is poured afterwards. The pillars are not really an important detail but they do indicate that there is a footer underneath for supporting a load. The metal brackets to attach a column can be put almost anywhere on a concrete slab but the key is what's underneath to support the load.

When you say you want them level, do you mean each pad is level to each other, or just each pad is level on top?
You shouldn't need to level them to each other as you can cut the posts off the right height similar building a deck.

"A temporary structure to lift 300 lb. from the roof of my car"? Why such a permanent solution to a temporary problem?
Get 3 strong neighbors and a 6-pack of quality beer--the entire job can be done in less than 10 minutes. Each man (counting yourself) only has to lift 75 lb.

Because I'd need to do it when I like, maybe once a week, before and after going camping, etc
The temporary is because I am going to build a garage tall enough for the truck to enter and I will have the lifting mechanism there once its done, but it will take approximately a year.
