This is a paving stone patio. The material is techo bloc blu 60- shale gray color. There is a accent band of hera 6x9 pavers chocolate brown color. The walls are techo bloc -mini creta shale gray color

Thanks! I looked at the mini-creta block and it is very rough to the touch (such as it will remove skin if rubbed against with shorts). Have you worked with the other new block by Techo-Bloc called Brandon?

Brandon is a smoother finish for sure. You aren't likely to be scratched by the wall. Your body usually only makes contact with the cap for a seating wall. We use the piedemonte cap quite a bit, a nice smooth finish that works well with mini creta. The brandon is a nice product as well.
