I've got a 10 yr old detached garage that was built on a driveway pad. I'd like to convert it into shop with an insulated floor. I'm trying to figure out the best way to level the existing concrete - as the structure was built on a pad, there's about 5" slope across the existing floor. I've assumed self-leveling concrete is the answer, but 5" is a lot to concrete to add, and it will "climb" the wall in that lowest corner (not sure how else to describe it). What do ya'll recommend?
After leveling, I'm planning on using something like Dricore for a subfloor and then cork flooring on top of that. I've got some experience with subfloor installation, but I've never done any self-leveling concrete. Thanks in advance!!
