Part of my basement floor has a ridiculous pitch - about 2" in 6 ft. The sump pit is also in this area. How can I level it?

2 in 72 is a bit much. You need a little to make the sump work, of course, but I’d imagine only half of that would be needed.

If you’re serious about trying to get to less slope, you could try to form up around the sump opening about an inch or so and lay in some new patch mix. The worst case is to break up the whole area and pour new, but that’s a ridiculous amount of effort.

I’m sure there are some expert mudders here who can tell you exactly how to pull this off.

Thanks, Cowboy Truckr. The floor is completely sealed around the sump pit because of the radon mitigation system. Radon gas can't get out; water won't be able to get in. So, I don't think floor pitch plays much of a role anymore in sump operation.

Self leveling compound is the way to go here. Just be sure to prime the floor first with the manufacturers recommended primer. If you don't the leveling may not stick right and start to crumble down the road.

Will self-leveling compound harden enough to be used as a wear surface? The floor will eventually be painted.

Wear surface as in foot traffic "YES" ,I put a 4'x4' pad on where my house and addition meet,wood sub floor then about 2" of leveling cement then tiled it 3 yrs ago. This catches 99% of my house traffic and has held up great.
