Flagstone over a Existing Concrete patio
We have a concrete patio which has some cracks on it that we would like to repair. We are also thinking of extending the patio. We do not want to rip up the existing concrete patio. We would like to put Flagstone over the existing patio. We live in PA. Does the Flagstone have to be cemented in, on top of the existing patio? Or can we just lay some sand over the concreted patio and then just lay the flagstone on top of that? Maybe we can use concrete just for holding down the flagstones on the edges? What do you recommend? Thank you for your time. By the way, you have a great website with lots of great information.
