My wife and I are Looking to re-do our patio, and trying to decide between natural thermal bluestone vs a concrete paver "slab" equivalent. Here in Ohio, I've only been able to find 3 total paver slabs that resemble natural thermal bluestone: Torino (Bluestone color) and Rivenstone (Bluestone color), both by Unilock, and Aberdeen (Azzuro) by Techo-Bloc. Initially, we really liked the look of Techo-Bloc's Aberdeen, but then we saw a 2nd installation, and the color had REALLY faded--so, we've kinda lost confidence in it. Unilock's Rivenstone looks pretty good, but it more resembles natural cleft Bluestone, which my wife doesn't like as well thermal. So, of the three, we think we like the Unilock Torino best. The problem we're finding, though, is that the product is so new that our local stores haven't sold any yet, so there are no installations we can go look at. (Our local store has a 4' x 5' sample installed on site, but that's all we've found.) If anybody out there has Unilock Torino on their patio, please post your review and any photos! Thanks!
