I'm thinking about installing ceramic tile over a concrete basement floor. The floor is flat for almost all of its expanse, but within a couple feet of the corners it starts to curl upward, and ends up higher by almost an inch.
The tile that I am thinking of using looks like wood planks, and is 6 inches wide by 24 inches long.
How do I overcome the problem in the upward-curling corners?
I personally would break out my grinder with a diamond wheel on it and grind it down. Being the grinder is round you would have to chisel the corner out. This can be dusty so you would need a vacuum. My grinder has a dust guard with a vacuum attachment, so if you can get a grinder with a diamond grinding wheel on it I would do that. If you can't rent a grinder with a vac attachment just have someone hold the hose right by the wheel as it grinds. Be ready for some dust and get some dust masks.
