how to replace hearth?

kingindcNovember 22, 2010

We are in the process of replacing the tile on our fireplace hearth with a piece of granite. The hearth is level with the fireplace box and the hardwood floor in the living room. I removed the tile and the grout down to the original concrete pad, and I've ordered a piece of granite, but I'm stumped on what to do next. The concrete pad is not level, and the opening in the floor is deeper than the granite slab. I don't know if I need to shim it somehow before I install the granite (with wood? or something fireproof?), or if I need to pour more concrete or add some other substance to make a perfectly level surface to the correct depth.

If anyone has any advice for me, I'd really appreciate it!

Whatever you do, the material you use must be fireproof. By definition, the hearth is that zone that could catch fire if it contains flammable material.
