Bought slate here
I bought an Indian Autumn slate to use in my back yard from Emser tile about 5 years ago. It's gorgeous and pretty thick. It seemed like pretty good quality. The stuff on my BBQ island 5 years later still looks perfect. However, the stuff near my lawn is flaking up a storm. It's a bit disappointing, but not really Emser's fault or anything. We just need to constantly seal it. I wish that someone would have given me an FYI, this is a terrible idea lecture about having it so close to the lawn.
I remember we got a good price on the tile and that for some reason, we picked it up ourselves which was a bit of an ordeal. You can see their warehouse from Miramar Road. I think I even bought the tile over the phone after finding out that they carried it.
