In the final stages of finishing a room in our walk-out basement. This particular room has a long history, as it was originally a garage. Thus, it has a slight pitch from the back of the room towards the wall that once contained the garage door (which is now a sliding glass door).
Unfortunately, there is a ridge down the center of the room where the concrete bows up about 3/8" of an inch over a 2' wide strip. I believe that this kind of ridge will cause issues when laying the laminate flooring.
My initial thought was to use self-leveling compound. However, being self-leveling, it will run down and pool quite thick at the front of the room, and require a significant amount to do (and might even go higher than the threshold of the sliding glass door).
I am unsure as to what type of product I could use that would be trawl on, and thick enough not to run, yet bond well with the underlying slab. Any thoughts on the best way to flatten a concrete floor that has a pitch in one direction that must be maintained?
