Construction/contractor question - flooring. Laminate over a concrete slab - I got a problem.

[Skip Intro]

Thought I'd give this a shot, google not being very helpful.

First of all, I know nothing about this stuff. I had a pipe burst, runined the carpet in my dining room, had to have it replaced. Got a couple of friends to put down laminate for me. Evidently a previous owner had tried to fix a crack in the concrete slab by pouring more concrete on top of the crack. But they didn't level it, so there is a "hump" in the slab. I never noticed it before, but now that the laminate is down, it is very noticable when you walk over the hump. It's in an area where one of the chairs sits on it, and I'm afraid the laminate will crack eventually.

Is there an easy fix?

Thanks.

1. no easy fix

that condition should have been discovered by whoever put down the flooring

2. What I feared. Let's say we pull up the flooring enough to get to the spot - then what?

How do you get rid of a lump of concrete?

4. guess you could grind or chip it down, depends on how much you need to remove

3. Take a floor buffer, put down some coarse sand and add

just enough water to make a slurry paste to grind the hump down flush. There's a real thin foam cushion that should be placed over the concrete to separate the laminate. PM me if this is confusing.
