Concrete Leveling

[GearBeer]

There's a sunken area in my workshop (~1/2" deep, 2' diameter) approximately where my welding table will be. I was going to fill it with leveling cement, but I've been told that I should skim coat the entire floor if I do this. Is this true? Is there a better solution (aside from leaving it low, like I'm thinking now).

Is the rest of the floor in solid, sound, condition?

What reason was given for that advise?

I have a similar issue in my garage. One corner is cracked and sloping. Drops about 6" from "slab grade". I am planning on jacking it up with some car jacks, backfilling under it with loose mix concrete, then skim coating the whole thing to prep for epoxy and to re-establish the slope since I get standing water near the doors.

The whole floor's in pretty good condition. It's freshly ground and crack-free.

The reasoning for skim coating the whole thing was presented to me as an issue of absorbtion quality.

Weld a 1/2" shim under one of the table legs so it doesn't wobble and forget it.

Wolverine has a product called trowelEase that is an epoxy/sand. Works well for an issue like you describe, but it is a little bit of a PITA to work with. I have also used a primer + concrete product on something similar (that was not epoxy coated) that worked well and was seamless.

rasit,

That's exactly where I'm at right now. I'm a little concerned that it will collect water, but that's what a squeegee's for, right?
