Hi,
I would like to have red brick surround the concrete back yard, like in the picture below. How thick is the concrete I have to have under the red brick? I was going to do a little bit to hold the bricks in place, by digging it down slightly, then throw some concrete, then place the bricks on top. My brother told me I have to have at least between 2" to 3" of concrete because this is a walk path. What do you, the experts, think?
Thanks.
