You are looking at stamped concrete my friends. Seriously. I was floored when I saw this and after a little research I found a link to a similar looking concrete stamp (click here). The applications are exciting to think about; deck, commercial floor/ office, or basement. Stained concrete and stamped can be a little pricier than standard poured concrete, but do make sure whoever you have install an application like this is well seasoned in installs like this one since it could be botched so easily. The above picture is from ASDierolf Concrete LLC from Texas and they know their stuff.
