Spin Zone / Leveling a concrete slab
« on: June 03, 2016, 07:24:55 AM »I am laying a high-quality laminate floating floor in my first home. I am doing the work myself. For those not familiar, this is the click-lock type flooring that comes in planks and locks together. It's gone quite well, except for a spot in the living room. The flatness of the subfloor is an important factor in the success of laying a floating floor. I say flat vs. level because uniformly out of level is fine, but changes in flatness beyond a certain tolerance are a problem. Too much variation in flatness can cause issues, including spots with a soft feel, and/or future problems with buckling or weakening of the locking mechanism.
Well, I've got a spot in the living room near the rear French doors that somehow I didn't notice before laying the floor. I have one of two problems - a high spot a few feet from the door, and/or a sloping toward the door. Sorta' like this, I think: --^-...||.
This job has been interesting and I am happy to do it. I'm not sure I'd do it again, though. So, has anyone had experience "leveling" a concrete floor? Unfortunately I'd have to pull up about 12 rows of flooring to do it. I know there is self-leveling compound but I have no experience with it. Plus, if what I have is a high spot rather than a low spot, I'm not sure if SLC is the answer. Probably grinding down the high spot is what'd be needed then, and I'm not prepared to do that.
Would a concrete contractor be the best to hire if I wanted to take care of this?
