Leveling a basement floor
I want to install an engineered floor in my basement, the floor is poured concrete in good condition. I have no moisture problems in the area I want to level.
The problem is that the floor slopes unevenly toward the floor drain as much as 4" in 13'. Slope also varies around the parimeter of the floor. I'm looking for the proper material to use to build up the floor. There is a floor leveling compound that is normally used as a bed for a shower stall base, there's also a self leveling material that when mixed with water seeks its own level. Both of these options are expensive, the second option the more expensive of the two. Another option would be concrete but just like the 1st option above minimum thickness problems arise. One other problem is about half the floor has linoleum tile which will have to come up. This is not a problem but the adhesive residue is. So what do you think, what is the best material/solution to this problem?
