leveling out concrete slab kitchen floor

When I bought my Lustron home in 2006, the plumbing in the kitchen had needed to be repaired. The 'plumbers' the previous owners (a bank that didn't care) called in fixed the plumbing okay, but didn't do well with the floor.

They pulled up the vinyl tiles that were in the corner, fixed the pipes, and poured concrete to fill in. The problem I have is that they didn't take the time to level the concrete at all. By the time I moved into the house, the concrete was set. Now I have a huge lump in the corner of my kitchen. I'm looking to put in new flooring and I would like to know the easiest way to fix the lump in the flooring. I thought about using a leveling concrete compound, but there is almost 1/2" above the existing floor, which is already too close to the threshold.

Please help!

Thanks, Cathy

Re: leveling out concrete slab kitchen floor

I had a similar problem with a high spot when re-carpeting a room.
I built 3 sided box about 24" and 18" along the sides. One long
side was left open but had a heavy towel with lots of surplus folds
stapled on three sides. The top was a piece of 1/8" plexiglass.
I positioned the box over the work area with a shop vac hose
poking thru the curtain. I used a 4.5" grinder to take down the
concrete. The box contained a large part of the dust which the
shop vac picked up. Had to stop and clean the dust off of the
inside of the top (window) regularly. Used acoustic ear muffs to
deal with the noise.

Worked for me.

Thanks for the info. I'm not sure that is something I'd be able to do with a new cat in the house. I don't want to kill him and I don't know of anyone that would be able to keep him while I'm grinding away at the floor.

Do you think it would work if I chipped away the lump until it was below the floor grade and used the concrete leveler to fill in? I was hoping not to have to call in someone to do it for me. I'm too poor for that.

Thanks again,
