We did our lanai and outside patio with river rock (not done by the guy most people recommend but who we used lived in the Villages ad we saw their work in some of the stores years ago in Spanish Springs so we hired them. Worst decision I could have made. It looked nice for awhile, we did the maintenance of having it resealed or whatever it is they do. We experienced it coming loose there were always posse stones it discolored on us really bad and within about 4 years it was disgusting looking, thousands of dollars down the drain. We then because our neighbors had used them had Stone Creations rip it all up and do one of their designs and it has been so much better. I know Stone Creations these days get bad reviews but about 3 or 4 years ago when we did this they did a great job. We have had it resealed and it still looks great! So that's our experience
Now for a garage our neighbor had that garage flooring put in I think it interlocks and they love it and it looks beautiful!
